Please help!
/usr/local/bin/ruby-build: line 387: make: command not found means rbenv can't compile Ruby because the necessary tools aren't available.
Have you installed Xcode?
Have you installed its associated command-line applications? That's the second step needed, and is found inside the Xcode application.
Have you recently updated Xcode? If so, you might need to update the command-line tools too.

I am trying to run command
rbenv install 2.0.0-p247
I tried to follow several steps by googling the errors that I faced but I am still not able to resolve the error
I got this error

Ruby 2.0.0 is very much past its end of life, so I'm assuming you have a specific reason you need install it. Otherwise, you are much better off installing a modern, supported version such as 2.7.x or 3.0.x.
Older versions of ruby were built with openssl#1.0. After 1.0 went end of life, ruby-build had a breaking change to require openssl#1.1. This means that ruby versions < 2.4 can no longer be installed/built directly using ruby-build (i.e., rbenv). This GitHub issue has details.
Homebrew has removed its openssl#1.0 formula, but you can still install it via an rbenv tap. The following might work for you, though the comments in the issue report mixed results depending on the version of Command Line Tools being used.
brew install rbenv/tap/openssl#1.0
RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl#1.0)" 2.0.0-p247
Note: if you are running on an M1 (Apple Silicon) Mac, you might be out of luck. AFIK, there's no intention of getting openssl#1.0 to to work on Apple Silicon.
When I try to create a new rails project on my PowerPC Mac OS X with ruby-2.4.2 and rails-5.1, it started to download and install various gems and during the build step of nokogiri-1.10 I got
cc1: error: unrecognized command line option "-Wno-array-bounds"
during the compilation of libxml2.9.9. I modified the
~/.chefdk/gem/ruby/2.1.0/gems/nokogiri-1.10.1/ext/nokogiri/tmp/powerpc-apple-darwin9.8.0/ports/libxml2/2.9.9/libxml2-2.9.9/Makefile
to comment out the error causing -Wno-array-bounds option and remade the project but it gave the same error again. I guess it's reverting back the original Makefile. How can I install nokogiri with a modified Makefile?
I am frustrated with installing OpenCV 2.4.6.1 on My MacBook Pro Mountain Lion, I've tried so many ways using MacPort, CMake, Cuda to no avail.
I followed the instruction from this site http://sadeepj.blogspot.sg/2012/03/installing-and-configuring-opencv-to.html to install and configure OpenCV in MacOS X. However, when I run in the command line '$ make' it always results in error at [30%].

Does anybody know how to resolve this?
Thank you very much in advance :)
I have figured out how to solve this and posted it here: https://sites.google.com/site/yonasstephenfyp2013/updates/tutorialinstallingopencvonmacosxmountainlion
the essence of solving this is using the right version of OpenCV. At the time I installed, the stable version was OpenCV 2.4.3. Don't go for the latest version because it might be compatible yet with the new MacOS OS
you could just skip the performance tests for now. (you can always build them later, once this got solved)
add:
-D BUILD_PERF_TESTS=OFF
to your cmake cmdline
[edit]
looks you're having issues #3191 and 3179
both of them are fixed in 2.4 now https://github.com/Itseez/opencv/pull/1228 , https://github.com/Itseez/opencv/pull/1244
when did you download the code ? might consider getting a fresh copy ?
I am trying to install PL/R 8.3.0.13.1 on my MacBook Pro running OS X 10.7.5, Postgres 9.2 and R 2.15.2. I have found on the web a nice step-by-step guide for Windows but I can't find anything similar for Mac.
I got stuck when I run this command [as official documentation] ( http://www.joeconway.com/plr/doc/plr-install.html ):
USE_PGXS=1 make
Output:
make: pkg-config: Command not found
make: pkg-config: Command not found
make: pkg-config: Command not found
make: pkg-config: Command not found
make: pkg-config: Command not found
*** Cannot build PL/R because R_HOME cannot be found.
*** Refer to the documentation for details.
Clearly that means I need to create somehow R_HOME, variable and/or location...
Any idea how to do it?
The error message is actually a bit confusing. If you look at the Makefile of PL/R, the logic is that it uses R_HOME to find R when set, otherwise it tries pkg-config. You have neither set, so it bails out.
I recommend going the pkg-config route if possible. The R_HOME route appears to assume an R installation scheme that might not be universally applicable. Perhaps it applies to builds straight from source.
The above applies to all platforms. Now on OS X, it depends on how you installed R. For example, if you used MacPorts, it would go something like this:
sudo port install pkgconfig
sudo port install R
and then build PL/R itself:
make USE_PGXS=1
But that will break because PL/R does not expect that MacPorts separates the R headers into two separate directories (architecture-dependent and -independent I suppose).
Homebrew might work better, but the principle is the same.
You need to figure out what you should set your PLR environment R_HOME variable. In a terminal session I get this
computername:~ username$ R RHOME #only enter stuff after"$"
/Library/Frameworks/R.framework/Resources
This is at the bottom of that page you linked to:
"Tip: R_HOME must be defined in the environment of the user under which PostgreSQL is started, before the postmaster is started. Otherwise PL/R will refuse to load. See plr_environ(), which allows examination of the environment available to the PostgreSQL postmaster process. "
This is from a webpage describing the problem and offering a fix:
To fix: Add a "R_HOME = '/usr/lib/R' " to /etc/postgresql/version/cluster/environmen
Example Fix for version 8.1:
$ sudo -s
# echo -e "\nR_HOME = '/usr/lib/R'" >> /etc/postgresql/8.1/main/environment
# exit
To Test:
$ sudo /etc/init.d/postgresql-8.1 restart
$ sudo -u postgres psql plr_test
plr_test=# select test();
test

This has been driving me crazy for 2 days.
I have been trying to install psycopg2 using easy_install and no matter what I try (i.e using gcc-4.0 instead of the snow leopard default one) I always get the same error:
error: Setup script exited with error: command '/usr/bin/gcc-4.0' failed with exit status 1
Please see: http://dpaste.com/hold/228252/
I have googled that error so many times and nothing I have found seem to help.
Looks like you're missing a dependency, the development files for libpq. The relevant log part is here:
In file included from psycopg/psycopgmodule.c:32In file included from psycopg/psycopgmodule.c:32:
./psycopg/psycopg.h:31:22: error: libpq-fe.h: No such file or directory
Try installing libpq development files and then rerun easy_install. You may hit another missing dependency; pay attention to the first error that GCC spits out.
Link http://dpaste.com/hold/228252/ seems to be dead, this is how I solved this problem (Mac OS X 10.6, virtualenv).
If pip fails with this message, just take a look to build folder in your virtual environment. You should edit setup.cfg file there, particularly include_dirs and library_dirs. In first one set your include folders, my option was:
include_dirs=/opt/local/include/postgresql84:/opt/local/include/postgresql84/server
and most likely you will need to set library_dirs to correct location as well:
library_dirs=/opt/local/lib/postgresql84.
probably you should install postgresql-devel first
yum -y install postgresql-devel
