I'm working on a Ruby project that requires the use of a few gems. I'm a bit confused, since I thought I already had bundler installed on my Mac. I tried installing it just now and got the following error:
Leias-MacBook-Pro:spec leia$ gem install bundler
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.
I then tried using --user-install, a trick I picked up from browsing Stack Overflow.
Leias-MacBook-Pro:spec leia$ gem install bundler --user-install
WARNING: You don't have /Users/leia/.gem/ruby/2.3.0/bin in your PATH, gem executables will not run.
Successfully installed bundler-2.0.2
Parsing documentation for bundler-2.0.2
Done installing documentation for bundler after 5 seconds
1 gem installed
Now, I kind of need the gem executables to run, so I opened my .bash_profile and dropped the following code in:
export PATH=/Users/leia/.gem/ruby/2.3.0/bin:$PATH
But no matter how I try to fix it, bundle still won't run. The gem I'm installing is rspec, and I definitely need to be able to run those executables. Am I doing something wrong here? I've tried to follow tutorials and Google similar issues, but I can't figure out what the problem is. Any pointers or suggestions?

I am trying to learn sass so I can develop my front end skills a little bit more because that is what I hope to be some day. The only thing is I can't get sass to work.
Whenever I run the sass --watch . command it returns this error.
>>> Sass is watching for changes. Press Ctrl-C to stop.
write ./test.css
LoadError: no such file to load -- rb-fsevent
Use --trace for backtrace.
I did a bit of research on this error and it was suggested on this site to just simply install the rb-fsevent file that is missing so I ran the gem install rb-fsevent command and then got this error.
Fetching: rb-fsevent-0.9.4.gem (100%)
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
so I did a bit of research on THIS error and it was suggested agin on this site to just run the install with sudo. So i did just that I didn't get an error so i was quite excited because I have been fighting with this for a while so i want back to the start of this question and ran the --watch command and got the same exact error. Can anyone help me fix this?
Your first error is because Ruby can't load the rb-fsevent gem. This could be because the gem is not installed. Trying to install the gem was a good idea.
Your second error is because you are trying to install the gem to a directory that you do not have permissions for. Using sudo to do the install is an acceptable solution. You can also do gem install --user-install to install to your home directory.
You are still getting the first error because even though the gem is installed, Ruby cannot load it. This could be because sudo installed the gem with the wrong permissions, or installed it to the wrong location, or Ruby is looking for it in the wrong location.
Thus your solution would be to
Locate the gem files you installed
Check that their permissions allow you to read them
Check ruby -e 'p $LOAD_PATH' to see if Ruby is looking in the right place for the gem
Found today I couldn't get my 'jekyll server' to start, so I preceded to reinstall 'jekyll' but I get this error...
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
Then I tried 'sudo gem install jekyll' and it worked!
Can anyone explain what's going on?
Thanks!
Use rbenv to setup a ruby binary that is in your home dir (a writable path).
You get that error because you lack write permissions to the System dir. Don't try to get write perms there - that's just asking for trouble. Instead, install a ruby version manager.
rbenv is linked above. Some like RVM. You can google for the arguments that pro/con each. rbenv is "more unix-like" and that is a good reason on its own.
It is installing system wide , you can force a single user install as follow
gem install jekyll --user-install
I am getting an error on jruby (linux) when installing the
"trinidad_diagnostics_extension" gem (though this question is not about trinidad). A chain of dependencies is
generating the error:
"trinidad_diagnostics_extension" depends on "jruby-lint >= 0.3.0"
"jruby-lint >= 0.3.0" in turn depends on "nokogiri >= 1.5.0.beta.4"
Before attempting to install "trinidad_diagnostics_extension", the relevant
part of my gem list looks like this:
$gem list
nokogiri (1.5.9 java)
jruby-lint (0.4.1)
As you can see, the needed dependencies seem already to be met. Nonetheless,
after adding gem 'trinidad_diagnostics_extension' to my Gemfile and then
running jruby -S bundle install, the bundler attempts to install nokogiri
(1.6.0.rc1), and during this installation fails with the following error:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
... bunch of omitted output here
nokogiri.c:42:18: fatal error: util.h: No such file or directory
compilation terminated.
make: *** [nokogiri.o] Error 1
Gem files will remain installed in /home/jg/.rvm/gems/jruby-1.7.3/gems/nokogiri-1.6.0.rc1 for inspection.
Results logged to /home/jg/.rvm/gems/jruby-1.7.3/gems/nokogiri-1.6.0.rc1/ext/nokogiri/gem_make.out
Why is bundler trying to install nokogiri when that dependency is already met?
How can I fix this? Successfully installing nokogiri 1.6 or making the trinidad extension aware that 1.6 does not need to be installed would both be fine solutions.
In case it's relevant I have JRUBY_OPTS=-Xcext.enabled=true
UPDATE
I was able to get it work by first installing the gem outside of bundler:
jruby -S gem install trinidad_diagnostics_extension
And then the bundle command worked fine, since it was already installed. So I got it working by I am still confused by why I had to install it outside of bundler and why that would matter, and would like some insight if anyone has it.
1.6.0.pre1 does not exist for the Java platform, for uninteresting reasons. That said, you should only get prereleases if you specifically ask for them.
I get an error while trying to install the ffi gem:

Building native extensions. This could take a while...

I'm getting frequent errors of all kinds while installing gems with native extensions, so I assume that there's something broken with my Ubuntu installation, but I've no idea what. I'll post any information you need to diagnose the problem.
EDIT: When I cd to the ffi gem (mentioned in the second but last line), and run the rake line in line 6, I get "Could not find RubyGem rake-compiler".
After gem i rake-compiler, and run rake again, I get this:
configure: error: source directory already configured; run "make distclean" there first
make: *** [/home/mdemare/.rvm/gems/ruby-1.9.2-p136/gems/ffi-1.0.6/build/x86_64-linux/ffi_c/1.9.2/libffi/.libs/libffi_convenience.a] Error 1

Update:
These are my rake gemspecs:
~ - 10:59>find ~/.rvm/ -name 'rake-0.8.7.gemspec'
~/.rvm/gems/ruby-1.9.2-p136/specifications/rake-0.8.7.gemspec
~/.rvm/gems/ruby-1.9.2-p136#global/specifications/rake-0.8.7.gemspec
~/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/gems/1.9.1/specifications/rake-0.8.7.gemspec
The last one is where gem looks, but that gemspec is different from the first one, and doesn't include the executable. Copying the long one doesn't quite solve the problem though - I get a file not found for the rake executable.
This caused me a ton of aggravation at the Boston Hack Day when trying to install Vagrant (for which FFI is a dependency). I ended up wasting so much time that I switched machines to work around the problem.
After the fact, I found a hack that works (although I'm sure there's a better solution). The file that the error message is complaining about
~/.rvm/gems/ruby-1.9.2-p180/bin/rake
differs from other similar copies in that it's missing path setup stuff at the head, so I copied these lines from one of the files that had them:
[genericized per #danv's answer below. Thanks for the improvement!]
ENV['GEM_HOME']=ENV['GEM_HOME'] || '~/.rvm/gems/ruby-1.9.2-p180'
ENV['GEM_PATH']=ENV['GEM_PATH'] || '~/.rvm/gems/ruby-1.9.2-p180:~/.rvm/gems/ruby-1.9.2-p180#global'
ENV['PATH']='~/.rvm/gems/ruby-1.9.2-p180/bin:~/.rvm/gems/ruby-1.9.2-p180#global/bin:~/.rvm/rubies/ruby-1.9.2-p180/bin:' + ENV['PATH']
That fixed it for me. This was a new Ubuntu 10.10 install with no default Ruby installation (which could be part of the problem) and Ruby 1.9.2 installed using RVM. Lots of other gems installed fine, including those requiring native compilation, so the problem is something specific to FFI.
I had a similar problem, and a workaround at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=529663 helped me.
In short, try to install the gem with:
$ rake=/usr/bin/rake gem install ffi
#Tom Morris - Tried your method and it worked fine.
I inserted your path specs (modified - see below) into ~/.rvm/gems/ruby-1.9.2-p180/bin/rake after line 12.
I modified the path specs so they are generic using ~ for the user home:
ENV['GEM_HOME']=ENV['GEM_HOME'] || "~/.rvm/gems/ruby-1.9.2-p180"
ENV['GEM_PATH']=ENV['GEM_PATH'] || "~/.rvm/gems/ruby-1.9.2-p180:~/.rvm/gems/ruby-1.9.2-p180#global"
ENV['PATH']="~/.rvm/gems/ruby-1.9.2-p180/bin:~/.rvm/gems/ruby-1.9.2-p180#global/bin:~/.rvm/rubies/ruby-1.9.2-p180/bin:"+ ENV['PATH']
Thanks for finding this fix!
Thanks #Tim Morris and #danv, your answers / comments helped. I adjusted for my setup, which is based more towards a superuser environment. Now this is what /usr/local/rvm/gems/ruby-1.9.2-p180/bin/rake looks like on my server:
require 'rubygems'
version = ">= 0"
ENV['GEM_HOME']=ENV['GEM_HOME'] || "/usr/local/rvm/gems/ruby-1.9.2-p180"
ENV['GEM_PATH']=ENV['GEM_PATH'] || "/usr/local/rvm/gems/ruby-1.9.2-p180:/usr/local/rvm/gems/ruby-1.9.2-p180#global"
if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then
version = $1
ARGV.shift
end
gem 'rake', version
load Gem.bin_path('rake', 'rake', version)
The installer attempts to run rake but fails when it isn't found:
can't find gem rake ([">= 0"]) with executable rake (Gem::GemNotFoundException)
You need to install the rake gem: gem install rake.
I installed Bundler on a pre-Rails 3 application and am trying to use it to install gems. My Gemfile contains the following lines:
source :rubygems
[...]
gem "RubyInline", "3.8.1"
However, when I run bundle install I get this error:
Fetching source index for http://rubygems.org/
Could not find gem 'RubyInline', required by 'memcache-client (= 1.6.3)', in any of the sources
The gem appears on the rubygems website:
http://rubygems.org/gems/RubyInline
Why is it giving me an error then?
I'm afraid this resolved itself after changes to fix other issues, and I'm not sure what the fix was. The source of several other issues was wrong permissions on various gems/binaries.
This kind of issue for me seems to be resolved on occasion by applying
bundle update
before
bundle install
The effect is to resolve old dependencies from when the bundle was originally produced and hence a gem that has been superseded (or whatever) will no longer be in the Gemfile.
