捆绑软件安装后，宝石不在本地宝石中 [英] Gems not in Local Gems after bundle install

问题描述

新机器.新安装了rbenv.新安装了rbenv-gemset.新安装的ruby-2.0.0.新的Rails 4.0.0应用程序.

New machine. New rbenv install. New rbenv-gemset install. New ruby-2.0.0 install. New rails 4.0.0 app.

当我

$ bundle install

从Rails应用程序目录中，我得到

from the rails app directory, I get

Your bundle is complete!
It was installed into ./vendor/bundle

但是，如果我那么

$ gem list

据说没有安装的宝石都没有出现.

none of the gems that were supposedly installed show up.

我跑了

$ rbenv rehash

为什么会这样?

其他信息:

$ which bundle
/usr/local/var/rbenv/shims/bundle
$ rbenv which bundle
/usr/local/var/rbenv/versions/2.0.0-p247/bin/bundle
$ rbenv which ruby
/usr/local/var/rbenv/versions/2.0.0-p247/bin/ruby
$ ruby --version
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0]
$ rbenv gemset active
blog
$ which rails
/usr/local/var/rbenv/shims/rails

推荐答案

您在此应用中的默认设置是安装到vendor/bundle.您可以通过安装gems后出现的It was installed into ./vendor/bundle文字来说明这一点.

Your default in this app is to install to vendor/bundle. You can tell this by It was installed into ./vendor/bundle text which appears after gems installation.

捆绑程序文档指定您必须通过--system才能在系统位置安装:

Bundler documentation specifies that you have to pass --system to install in system location:

--system: Install to the system location ($BUNDLE_PATH or $GEM_HOME) even
          if the bundle was previously installed somewhere else for this
          application

更多的解释是，不使用bundle exec时，您的红宝石只知道使用--system选项安装的宝石.您可以从vendor/bundle或运行bundle exec gem list或(如Casper注意到的)bundle list选择的任何路径中查看宝石.现在，您是要在系统位置还是在应用程序目录中放置宝石.

More explanation is that your ruby knows only about gems installed with --system option when not using bundle exec. You can see your gems from vendor/bundle or whatever path you've chosen by running bundle exec gem list or (as Casper noticed) bundle list. Now it is your choice whether you want your gems in system location or in application directory.
