bundle:找不到命令

Question

我通过以下教程正确安装了vps,ubuntu 10.04,rails 3,ruby和mysql.如果我运行bundle check或bundle install我收到错误'-bash:bundle:command not found'.从gem list --local我看到'bundler(1.0.2,1.0.0)'已安装.

我不知道出了什么问题......

gem environment 收益:

 RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.7
  - RUBY VERSION: 1.8.7 (2010-04-19 patchlevel 253) [i686-linux]
  - INSTALLATION DIRECTORY: /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8
  - RUBY EXECUTABLE: /opt/ruby-enterprise-1.8.7-2010.02/bin/ruby
  - EXECUTABLE DIRECTORY: /opt/ruby-enterprise-1.8.7-2010.02/bin
  - RUBYGEMS PLATFORMS:

  - GEM PATHS:
     - /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8
     - /root/.gem/ruby/1.8
  - GEM CONFIGURATION:
     - :update_sources => true

     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:

并echo $PATH返回:

/opt/myruby/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/bin/gem:/opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/:/root/.gem/ruby/1.8

并which gem返回:

/usr/bin/gem

locate bundle 收益:

/opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/

我的问题是我做了:

sudo gem install bundler

所以我安装了root而不是我自己.所以我以root身份卸载,然后安装为我自己:

sudo gem uninstall bundler
gem install bundler
rbenv rehash

(如果你使用rbenv的最后一个命令)

它奏效了."正确的"路径是在.bashrc(或其他壳轮廓),至少根据

$PATH
=> zsh: /Users/myself/.rbenv/shims:/Users/myself/.rbenv/bin: ... etc

但它期待它为我自己安装 - 而不是为root.在我的情况下,它的合法安装地点在~/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/bundler

您需要将ruby gem可执行文件目录添加到路径中

export PATH=$PATH:/opt/ruby-enterprise-1.8.7-2010.02/bin

Answer 3

...也适用于Debian GNU/Linux 6.0 :)

export PATH=$PATH:/var/lib/gems/1.8/bin

Answer 4

我这样做了(Ubuntu最新截至2013年3月[我认为:)]):

sudo gem install bundler

归功于Ray Baxter.

如果你需要gem,我用这种方式安装Ruby(虽然这是长期征税):

mkdir /tmp/ruby && cd /tmp/ruby
wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p327.tar.gz
tar xfvz ruby-1.9.3-p327.tar.gz
cd ruby-1.9.3-p327
./configure
make
sudo make install

可能发行版验证路径是将其添加到您的 .bashrc 或 .zshrc，无论您的 shell 是什么：

PATH="$(ruby -e 'print Gem.default_dir')/bin:$PATH"

或者如果您已在用户范围内安装了 gem，请使用：

PATH="$(ruby -e 'print Gem.user_dir')/bin:$PATH"
