rubygems-bundler && Noexec
Let's stop using
bundle exec, kthx.
Introduction of the 1.0.0 release: http://niczsoft.com/2012/05/rubygems-bundler-integration-gem-1-0-0/
gem install rubygems-bundler
Next run (once):
And you're done!
It's no more required to modify
just remove the old entry to be sure it works as expected.
In case you need to use your own
you can define it in
~/.gemrc to override the default:
custom_shebang: $env <your_custom_shebang_program>
Though you can let noexec do it's own thing and rely on looking up your binary via your Gemfile, you can also specify which binaries you want included or excluded. Create a .noexec.yaml file along side any Gemfiles you want to use. Then, to enable (or disable) the usage of your particular binary into your bundle, add an include or exclude section. For example:
In case you need explicitly skip loading
Bundler.setup, prefix your command with
The old method is still available and might kick in if your tools use
NOEXEC environment variable:
NOEXEC=0 rails new app NOEXEC=skip gist
skip will disable the gem, this method is deprecated and will be removed with 1.2.0.
Things not going the way you'd like? Try your command again with
NOEXEC_DEBUG=1 set and create a ticket. I'll fix it right away!
If you do not get relatively fast an answer make sure to leave an email to secure an later answer.
How does this work (ruby_noexec_wrapper)
It modifies gem wrappers shebang to load
Then, when you run gem binaries, it takes a look at your working directory,
and every directory above it until it can find a
If the executable you're running is present in your Gemfile,
it switches to using that
Gemfile instead (via
Rubygems and Bundler integration, makes executable wrappers generated by rubygems aware of bundler.
rubygems-bundler was merged with noexec gem in version 0.9.0.
rubygems-bundler-uninstaller gem uninstall rubygems-bundler
this will set all gems to
/usr/bin/env ruby which is one of the safest choices (especially when using rvm).
In case of rvm additional steps will ensure this gem is removed and not installed again:
rvm get stable --without-gems=rubygems-bundler rvm all-gemsets do gem uninstall --all --executables rubygems-bundler
