I've been trying to upgrade my OpenCV2 to OpenCV3 on my macOS Sierra 10.12.5, using homebrew and also have its bindings for both Python2 and Python3.
Following the excellent guide at pyimagesearch, I got to run
brew install opencv3 --with-contrib --with-python3 --HEAD
(I first uninstalled OpenCV, just for clarity and to avoid any potential conflicts). Now, the guide explains that --with-contrib is downloading additional stuff, which is good to have; --with-python3 is downloading the bindings for Python3 (those for Python2 are automatically there); --HEAD is pulling the Github branch version rather than the tagged release, which is a workaround to a problem related to the QKIT Apple library.
My problem is I get a
Error: Directory not empty - (/usr/local/Cellar/numpy/1.13.1, /usr/local/Cellar/numpy/1.13.1.tmp)
A brew doctor tells me Numpy is not linked but I'm not exactly sure what'd be the best way to proceed here. Wouldn't want to break something.
At this point, I just tested installing just the bindings for Python2, as in
brew install opencv3 --with-contrib --HEAD
and this leads me to this other problem:
Error: No such file or directory - /private/tmp/opencv3-20170714-55298-snr5jb/3rdparty/ippicv/downloader.cmake,
which is solved with if I instead run
brew install opencv3 --with-contrib
This last one works, I got OpenCV3 for Python2. Apparently I don't have the HEAD issue.
Now though, I still want the bindings for Python3 as well and due to the Numpy error above I'm not sure how to proceed? It seems like it's trying to install Numpy as a dependency, which I have already.
brew install opencv3 --with-contrib --with-python3 --HEAD
Instead of :
brew install opencv3 --with-contrib --with-python3 --without-numpy
and See this :

I installed lua on my OSX 10.10 machine using brew install lua. The version that got installed was 5.2.4. LuaRocks was installed along with the lua package. But when i run luarocks install <package_name> i get Error: ##HOMEBREW_PREFIX## does not exist and your user does not have write permissions in. i tried using sudo luarocks install <package_name> as well, but it gives the same error. How to fix this ?
Please Help.
Thanks
This was a bug in the way we relocate text files to ensure wider bottle portability for non-/usr/local users.
It was resolved a couple of weeks back, July 31st I believe. Presuming your Homebrew is in a standard location, if you do:
rm /usr/local/etc/luarocks52/config-5.2.lua && brew update && brew reinstall lua
The problem should be resolved now. Apologies!
I had the same problem when using the luarocks when installed with homebrew, try installing luarocks again like this:
$ wget http://luarocks.org/releases/luarocks-2.2.1.tar.gz
$ tar zxpf luarocks-2.2.1.tar.gz
$ cd luarocks-2.2.1
$ ./configure; sudo make bootstrap
I took this code snippet from here: https://luarocks.org/
I managed to install all the modules that I required without problems after doing this.
I'm attempting to re-install Ruby 1.9.3 with a patch that will allow me to use ruby-debug.
When following the instructions and running
rvm reinstall 1.9.3 --patch debug --force-autoconf
It runs through and after applying the patch spits out:
rvm requires autoreconf to install the selected ruby interpreter however autoreconf was not found in the PATH.
Unfortunately, googling around for how to install autoreconf on OS X v10.7 (Lion) (or much information about it at all) seems to be a dead end.
If you are using Homebrew, try
brew install automake
Which should also install autoconf and allow rvm to finish installing.
If you want to do this using MacPorts instead of Homebrew, you can do:
sudo port install automake autoconf libtool
I had the same problem and this solved it for me.
If you're using brew, then the autoreconf utility is part of the autoconf package, so install it via:
brew install autoconf
If the problem persists, consider either reinstall or link it again. Use locate autoreconf to find out where it is.
Also check if /usr/local/bin/autoreconf exists (and is linked into the right place), and you've the /usr/local/bin path added in your /etc/paths file.
By downloading the .pkg file from MacPorts and installing it, it does the trick for me.
I had a similar problem, but because Homebrew moved away from the Cellar directory, but for some reasons binaries of this package were still there.
I reinstalled autoconf with the following command and autoreconf is in the right PATH now: brew reinstall autoconf
I solved my autoreconf problem adding the path to my shell:
sudo pico /etc/paths
then I added the line
/sw/bin
where I found the autoreconf and autoconf files and saved everything.
Since then I can use autoreconf without any problems.
According to rvm requirements, "For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba'"
I am completely new and am not familiar with terminal commands. How can I install libksba without using homebrew?
Please help!!!
I just installed libksba and its dependency libgpg-error from source and I can assure you that installing Homebrew and then installing libksba is much more straightforward. With Homebrew, you'll spend far less time dealing with terminal commands and the likelihood of success is considerably higher. It is popular for a reason.
For the benefit of future visitors, here are instructions to compile and install libgpg-error and libksba from source via bash without Homebrew:
cd /usr/local/src
curl -O ftp://ftp.gnupg.org/gcrypt/libgpg-error/libgpg-error-1.9.tar.gz
tar -xvf libgpg-error-1.9.tar.gz
cd libgpg-error-1.9/
./configure
make
make install
cd ..
curl -O ftp://ftp.gnupg.org/gcrypt/libksba/libksba-1.2.0.tar.bz2
tar -xvf libksba-1.2.0.tar.bz2
cd libksba-1.2.0/
./configure
make
make install
you need to install the command line tools of xcode. Then you don't need to install libksba.

When I try do install rmagick I get the following error message:
Can't install RMagick 2.13.1. Can't find MagickWand.h.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
I'm on Mac OSX 10.6.8, ruby 1.9.2p290, rvm 1.10.2.
Can anyone help me please to solve this problem.
If you're on Ubuntu, installing this package is what fixed it for me:
sudo apt-get install libmagickwand-dev
It looks like ImageMagick 7 changed include file path.
On building rmagick, since it includes file as wand/MagickWand.h There are no workarounds. It looks like sticking with ImageMagick 6 for now.
On Mac OS X (I tested on Sierra), I used HomeBrew's versions tap like:
brew tap homebrew/versions
brew install imagemagick#6
Then, use the path shown on above installation:
PKG_CONFIG_PATH=/usr/local/opt/imagemagick#6/lib/pkgconfig gem install rmagick
To install with ImageMagick 6.
I didn't want to mess with environment variables since I wanted bundler to be able to compile this gem on its own on a CI machine. Instead, I used Homebrew to install pkg-config:
brew install pkgconfig
and the next time I tried compiling the RMagick gem it found the header file without issue.
(This is pkg-config 0.28, ImageMagick 6.8.0-10, and RMagick 2.13.2, all on Mountain Lion.)
I had a similar issue with running
$ gem install rmagick
First of all, do you have imagemagick installed? If you're not sure, run
$ convert --version
If you do, you probably either installed it with fink or macports (maybe homebrew?). What is happening is that rvm can't find the imagemagick directory.
After reading
https://superuser.com/questions/361435/i-have-compiled-imagemagick-on-my-centos-and-rmagick-wont-install
I exported the imagemagick path by adding
$ export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH"
to my ~/.bash_profile, sourcing the new profile, then running:
gem install rmagick
It worked for me after I did this.
fix this setting the include path of your current imagemagick installation:
Install ImageMagick with brew
brew install imagemagick
find library
$ mdfind MagickWand.h
/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/wand/MagickWand.h
Install rmagick gem
$ C_INCLUDE_PATH=/path/MagickWand.h gem install rmagick
example:
$ C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/ gem install rmagick
I marked this as a favorite because it seems to come back to bite me with every new system I need to install RMagick on (and time has passed and version numbers have rolled).
Mac OS X 10.8.4
rvm 1.22.3
ruby-2.0.0-p247
Xcode 4.6.3 developer tools installed
$ brew install imagemagick
==> /usr/local/Cellar/imagemagick/6.8.6-3
$ brew install pkgconfig
==> /usr/local/Cellar/pkg-config/0.28
$ C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.6-3/include/ImageMagick-6 PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.6-3/lib/pkgconfig/ gem install rmagick
Successfully installed rmagick-2.13.2
Many thanks to everyone who added helpful answers above!
Mac users using brew
If you can use v6 of ImageMagick instead of 7, you can try this
brew install imagemagick#6 --force && brew link imagemagick#6 --force
Note this will unlink your existing IM installation, so be careful if you have other projects on your machine using ImageMagick without problems.
For my own and others edification, I got past the error about the magicwand.h by using the suggestion xonico. MDFind plus the C_INCLUDE_PATH. However, it then gave me an error about MagickCore.pc. My final command to get this working had to include both like so:
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/ PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/lib/pkgconfig/ gem install rmagick
Obviously your paths will vary depending on whether you're using brew like me and what version of imagemagick you were installing. Also, xcode command line tools did have to be installed, as others have mentioned.
Thanks for everyone's posts on this! I am plussing your answers since it contributed to mine!
For Ubuntu:
sudo apt-get install imagemagick libmagickwand-dev
gem install rmagick
I had a problem after update to Maverics.
It have lost a lot of linkings.
In my case I had to refresh links to pkg-config
brew unlink pkg-config
brew link pkg-config
Then installing rmagick worked like a charm.
I updated to Mountain Lion and started getting this same problem. I had to re-install brew, XCode, the XCode tools - pretty much the whole environment!
I eventually solved this problem using the answer from phopkins above...
brew install pkgconfig
Once that was successfully completed (I had to delete some old symlinks first) then I was able to successfully install the RMagick gem
This worked for me on Mac OsX
Install Imagemagick:
brew remove imagemagick
brew install imagemagick
Make sure pkg-config is correctly linked:
brew uninstall pkg-config
brew install pkg-config
brew unlink pkg-config && brew link pkg-config
Install gem
gem install rmagick
For Ubuntu users:
It will never done directly on Ubuntu. You should first install packages to run this command...:
sudo apt-get install libmagickwand-dev
...and then do install:
gem install rmagick
You may get the same issue, for that, Try clearing your apt repository and removing any broken packages first:
sudo apt-get update
sudo apt-get autoclean
sudo apt-get clean
sudo apt-get autoremove
If the system identifies any broken packages, forcefully remove them (replace package_name with your own):
sudo dpkg --remove -force --force-remove-reinstreq package_name
Then re-install any missing packages again. :)
An issue for me was that rmagick is out of date and not updated regularly. If you have too new of an ImageMagick version, then it might not be compatible. Check your version of ImageMagick using the following:
$ convert --version
If the ImageMagick version is > 7, it is not compatable with rmagick. The user will get errors such as
Can't install RMagick 2.16.0. Can't find MagickWand.h.
*** extconf.rb failed ***
Go back to version six of ImageMagick until they update rmagick to be compatible with version seven of ImageMagick. Someone has hosted the appropriate version(6) in a separate gem - 'imagemagick#6'.
If you need rmagick to work but currently have an imagemagick version 7 or higher, here are the steps to switch:
$ gem install imagemagick#6
$ brew unlink imagemagick
$ brew link imagemagick#6 --force
Helped me on Debian Wheezy 64bit
apt-get install libmagickcore-dev libmagickwand-dev
Try reinstalling both Imagemagick and PkgConfig. That should fix it for Mavericks
brew update && brew upgrade
brew reinstall imagemagick
brew reinstall pkgconfig
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick gem install rmagick
I was really struggling with this on OS X Mountain Lion (after upgrading from Lion) and none of the suggestions regarding C_INCLUDE_PATH, PKG_CONFIG_PATH, ln'ing various files, etc., were working. On the same day I upgraded to Mountain Lion, I also upgraded XCode to 4.5.2, but I didn't really think too much of this.
Eventually I stopped trying to install RMagick and had to pass on the work to a colleague.
Then, by chance, I found that I was trying to use bundle install on another project and I wasn't able to install the json gem because "make" could not be found. I checked into that and found you need to go to XCode -> Preferences -> Downloads and install the command line tools to get make working again. The json gem installed fine.
Then I paused...and tried
gem install rmagick
One more time. It worked perfectly.
for a rails based application, I found this
sudo apt-get install -y libmagickwand-6-headers
C_INCLUDE_PATH=/usr/include/ImageMagick-6 gem install rmagick
bundle update rmagick
bundle install
worked on debian jessie
I ran into this because I'd run OS X's Migration Assistant and nothing was relinked after the migration. You need to check the output of Wand-config --ldflags --libs. In my case it gave:
$ Wand-config --ldflags --libs
/usr/local/bin/Wand-config: line 50: pkg-config: command not found
/usr/local/bin/Wand-config: line 53: pkg-config: command not found
After relinking pkg-config, libpng, and libfreetype, that became:
$ Wand-config --ldflags --libs
-L/usr/local/Cellar/imagemagick/6.8.8-9/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16
-L/usr/local/Cellar/imagemagick/6.8.8-9/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16
And then:
$ gem install rmagick

Package MagickCore was not found in the pkg-config search path.
Perhaps you should add the directory containing `MagickCore.pc'
then:
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
in my .bashrc file to pick up MagickCore.pc, then created two symlinks:
ln -s /usr/local/include/ImageMagick/wand /usr/local/include/ImageMagick-6/wand
ln -s /usr/local/include/ImageMagick/magick /usr/local/include/ImageMagick-6/magick
Now:
$ gem install rmagick
Building native extensions. This could take a while...

boom everything works fine.
At arch linux, after installing imagemagick#6, gem wasn't able to install package rmagick and got error below.
Can't install RMagick 2.16.0. Can't find MagickWand.h
Worked for me using below steps
added pkgconfig path to .bashrc
export PKG_CONFIG_PATH="/usr/lib/imagemagick6/pkgconfig"
Created two symlinks as below
ln -s /usr/include/ImageMagick-6/wand /usr/include/ImageMagick-6/wand
ln -s /usr/local/include/ImageMagick/magick /usr/include/ImageMagick-6/magick
There are some variants to this problem. Mostly the case is dealing with a legacy application that run older versions of ruby.
rmagick has a dependancy on imagemagick... but not just any. If you've gone too far ahead, it may be wise to backtrack:
brew uninstall imagemagick
Then proceed with an appropriate version
brew install imagemagick#6
then you path needs to be adjusted and forced upon homebrew
export PATH="/usr/local/opt/imagemagick#6/bin:$PATH"
brew link --force imagemagick#6
then you can install rmagick to most recent or versioned
gem install rmagick -v '2.15.4' --source 'https://rubygems.org/'
I had a hard time getting this same issue to work when I had a default ImageMagick install on OSX 10.8 (no homebrew or macports). No combination of the suggestions in this thread or threads linked to from this thread worked for me (modifying the paths for my local install of course).
I simply deleted the default ImageMagick 6 install, and then reinstalled with macports. My rmagick install worked immediately after with no other changes.
on OSX Maverick 10.9.1
it took me ages to figure it out but I solved these issues the following way:
nano /etc/paths
changed:
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
into:
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
that that local stuff, like 'brew' is loaded first.
now I hit 'brew doctor' into the terminal, to see if there's something messed up
if you get the following output
Your system is ready to brew.
everthing is fine. if not ti will tell you what to do. Like kick out unbrewed stuff, broken libs, clean symlinks and whatnot.
When you are ready to brew, you need ghostscript(for pdfs), libpng, imagemagick via brew.
then you can happily type : 'gem install rmagick', in case you did't kill your ruby setup. But thats easy to reinstall via your cleaned up brew.
PS:
another helpful command is: 'which convert', to show you what version of imagemagick is used by the system.
as well as --version
so if you installed git via brew and do 'git --version' and it returns some apple git version, your load path is broken...
On Mac OS X 10.9, try to update your Xcode if there's a warning about it.
$ brew doctor
I you found some warning, do:
$ sudo /Developer/Library/uninstall-developer-folder
Then try:
$ bundle install
again
That worked fine for me.
On CentOS 6.5 x64, it was pretty easy:
yum install ImageMagick ImageMagick-devel
gem install rmagick -v '2.13.2'
I was able to fix this by upgrading to 2.13.2
All brew options failed to install rmagick 2.13.1 on yosemite 10.10
this worked
get the latest RVM
\curl -sSL https://get.rvm.io | bash -s stable --ruby
rvm install 2.1.1
rvm use 2.1.1
download and install the package file
http://cactuslab.com/imagemagick
(I used pacifist to install)
Confirm location of MagickCore.pc file
mdfind magickcore.pc
eg. /opt/ImageMagick/lib/pkgconfig/MagickCore.pc
Manually download rmagick-2.15.2.gem file
https://rubygems.org/gems/rmagick/versions/2.15.2
from that dir
sudo C_INCLUDE_PATH=/opt/ImageMagick/include/ImageMagick-6/ PKG_CONFIG_PATH=/opt/ImageMagick/lib/pkgconfig gem install --local rmagick-2.15.2.gem
If you are having issues with bundle installer still complaining about 2.13.1
In your gem file / gem.lock file upgrade ALL dependencies
rmagick (2.13.1) - > rmagick (>= 2.15.2)
Got same error for alpine 3.9 image build. It comes with ImageMagick 7.0.8.38-r0
To fix that you either use alpine 3.5 with ImageMagick 6.9.6.8-r1:
FROM alpine:3.5
Or install ImageMagick 6.9.6.8-r1 with package repository for 3.5:
RUN apk add imagemagick-dev=6.9.6.8-r1 --repository http://dl-3.alpinelinux.org/alpine/v3.5/main/
There is an open issue in rmagick repo regarding failed builds for ImageMagick 7.0.x. so hopefully it will be fixed soon.
