I'm trying to get Compass installed on a 2020 Mac Book Pro running Big Sur (11.5.2).
When I try and run:
gem install compass
I get the error:
You don't have write permissions for the /Library/Ruby/Gems/2.6.0 directory
If I try and run:
sudo gem install compass
I get the error:
ERROR: Error installing compass:
ERROR: Failed to build gem native extension.
current directory: /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.4/ext/ffi_c
I've tried installing and updating Ruby.
I've tried updating the system Ruby, but the system doesn't allow a more recent version than the below:

Anyone have any ideas on how to get Compass installed?
This really decomposes to two issues, as you noticed with the sudo call.
(1) You're trying to write gems to the protected directory for your system Ruby.
In most development environments, it's best to install a Ruby version manager that allows you to install multiple Rubies side-by-side for different projects. Purely subjectively, I'd recommend rbenv to manage only Ruby, or asdf to manage Ruby versions along with other languages versions. However, the question of which Ruby version manager to use is very well tread already, so you can pick the solution that's best for your needs with existing information.
(2) You're installing a gem with native extensions, which means that you need the underlying C libraries installed on your system to build correctly (assuming you're using CRuby, the default Ruby implementation). You'll need to install libffi-dev on your machine to build that gem correctly. Based on this question, it seems a simple brew install libffi should work for that.
Lastly, I'll suggest that it's idiomatic to use the bundler gem to manage gems per-project with Ruby. I'd reconsider if you really want to run this gem system-wide, or if it might vary versions across multiple projects.
After installing pik and changing my Ruby version to 2.0.0, bundler no long works properly

Gem::InstallError: The 'atomic' native gem requires installed build tools.
Please update your PATH to include build tools or download the DevKit

An error occurred while installing atomic (1.1.14), and Bundler cannot continue.
Make sure that `gem install atomic -v '1.1.14'` succeeds before bundling.
Installing the devkit from Ruby Installer sort of defeats the reason why I went to the trouble of installing pik. How can I fix this, so that in the future, I can easily update ruby using pik and still have everything working?
I had the same problem - if you follow the instructions listed (ie installing devkit and following their directions [they don't actually tell you to use rubyinstaller]), you'll be fine. Also make sure that during the init phase of the Devkit instructions that it doesn't miss any of your ruby installations.
A note though, it seems that pik can't specify the x64 version of 2.0.0, so you may run into problems if that's the case. In the end I had to use the rubyinstaller for the x64 version of ruby, and then ran the x64 version of the devkit.
Hope this helps.
I think Josh' answer is probably right, but I actually installed Ubuntu as a VM in the end, just so I could use RVM.
RVM is a thousand times better than Pik, and it installs the DevKit. It's so good it's genuinely worth installing Ubuntu just so you can use it.
I need to use ruby 1.8.6 to run a legacy script. I've installed NetBeans 6.9.1 and I'm trying to use the fast debugger but when I try to install it I get:

This is probably because the ruby version is too old, but is there a way to tell Netbeans to use a different version for ruby-debug-ide. I can install withouth problems ruby-debug-ide 0.10.0.
I'm using Ubuntu 10.04
In order to use ruby-debug-ide 0.4.9 with Ruby 1.8.6, you have to install ruby-debug-base 0.10.3 and linecache 0.45.
To know and manage your gems in Netbeans :

I've installed a instantrail2.0. I want to install watir 1.65
First I installed watir-1.6.5.gem it said 302 fetching http://gems.r....
then I downlord a rubygems-update-1.3.7.gem and type
gem install --local rubygems-update-1.3.7.gem
successfully installed.
then I type in update_rubygems
next I type in gem install watir-1.6.5.gem
but it appears ERROR:Failed to build gem native extension
I searched and found an answer that 1.3.7 doesn't support win32.
then I type
gem install sqlite3-ruby -v 1.3.0 gem install watir-1.6.5.gem
ERROR:Failed to build gem native extension
gem install sqlite3-ruby -v 1.2.3 gem install watir-1.6.5.gem
ERROR:Failed to build gem native extension
How can I do next??
use a more current version of Watir
I second Zeljko, going with the latest versions of rubygems and watir totally makes sense. If you must stick to older gems, try installing Ruby DevKit and then do the gem install to see if that helps.
What version of Ruby are you using? You should be using Ruby 1.8.6 with that version of Watir. I am also wondering if part of your problem is that you are doing a local install, instead of installing from internet. Local installs of Watir are difficult because of all of its dependencies.
Update: Check out this follow-up question: Gem Update on Windows - is it broken?
On Windows, when I do this:
gem install sqlite3-ruby
I get the following error:

Same thing happens with the hpricot gem. I seem to remember these gems installed just fine on < 1.0 gems, but now I'm on 1.2.0, things have gone screwy.
I have also tried this:
gem install sqlite3-ruby --platform Win32
Needless to say, this doesn't work either (same error)
Does anyone know what is going on here and how to fix this?
Update: Check out this follow-up question: Gem Update on Windows - is it broken?
As Nathan suggests, this does appear to be related to the fact that the latest versions of the sqlite3-ruby and hpricot gems don't appear to have Windows versions. Here's what to do when faced with this situation (note, the name of the gem is automatically wildcarded, so you can type just sql and get a list of all gems beginning with sql):
$ gem list --remote --all sqlite
*** REMOTE GEMS ***
sqlite (2.0.1, 2.0.0, 1.3.1, 1.3.0, 1.2.9.1, 1.2.0, 1.1.3, 1.1.2, 1.1.1, 1.1)
sqlite-ruby (2.2.3, 2.2.2, 2.2.1, 2.2.0, 2.1.0, 2.0.3, 2.0.2)
sqlite3-ruby (1.2.4, 1.2.3, 1.2.2, 1.2.1, 1.2.0, 1.1.0, 1.0.1, 1.0.0, 0.9.0, 0.6.0, 0.5.0)
Then you can choose the version you would like to install:
gem install sqlite3-ruby -v 1.2.3
To successfully install hpricot, I did this:
gem install hpricot -v 0.6
Annoyingly, doing a gem update tries to update the gems to their latest, broken-on-Windows, versions. When the update routine encounters an error, it ditches you out of the whole process. There's a (hacky) solution to this problem here.
So, is this issue a bug in gems? Should gems not automatically detect the platform and install the latest compatible version?
I had the same problem on Ubuntu, this solved the problem for me:
http://newsgroups.derkeiler.com/Archive/Comp/comp.lang.ruby/2008-08/msg00339.html
first from sqlite.org(http://www.sqlite.org/download.html)
download ->
Precompiled Binaries: sqlite-dll-win32-x86-3071700.zip
and Source Code: sqlite-autoconf-3071700.tar.gz
then extract as:
-include
--sqlite3.h
--sqlite3ext.h
-lib
--shell.c
--sqlite3.c
--sqlite3.def
--sqlite3.dll
last install gem like:
gem install sqlite3 --platform=ruby -- --with-sqlite3-include=path\to\include
--with-sqlite3-lib=path\to\lib --no-ri --no-rdoc
Good luck!
Is it possible that the newest version has not yet been ported to Win32 yet? Since this particular gem does have bindings to compiled code, it would require a platform-specific gem. If I force installation of version 1.2.3 rather than the current 1.2.4, the platform-specific version does install, but when I allow gem to try to install the current version, I get the generic 1.2.4 version (in the gems library folder, it lacks the -x86-mswin32 suffix that the other sqlite3-ruby folders have in their names.
Maybe someone else can answer how gem handles platform specific gems. Are separate gems uploaded for each platform and the gem software selects which one to pull down?
I also ran into this problem. It's worth knowing that the difference between 1.2.3 and 1.2.4 is not significant. Here are the 1.2.4. release notes:
Release Name: 1.2.4
Notes: This release only updates the
generated C file to reflect the
compatibility changes that were made
to the SWIG file. Binary builds (e.g.,
Windows) are not affected, and need no
update. In general, you will not need
this update unless you are using a
version of Ruby prior to 1.8.6.
(source: 1.2.4. release notes)
Hope that helps others!
I had the same problem on Windows and I have installe MinGW
http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/MinGW%205.1.6/MinGW-5.1.6.exe/download
and the problem has gone :-)
