Bundler: Command not found
提问by raphael_turtle
I am hosting on a vps, ubuntu 10.04, rails 3, ruby and mysql installed correctly by following some tutorials. If I run bundle checkor bundle installI get the error '-bash: bundle: command not found'. From gem list --localI see 'bundler (1.0.2, 1.0.0)' is installed.
我在 vps、ubuntu 10.04、rails 3、ruby 和 mysql 上托管，按照一些教程正确安装。如果我运行bundle check或bundle install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。
I don't know what's going wrong...

You need to add the ruby gem executable directory to your path
您需要将 ruby gem 可执行目录添加到您的路径中
export PATH=$PATH:/opt/ruby-enterprise-1.8.7-2010.02/bin

My problem was that I did:
我的问题是我做了：
sudo gem install bundler
So I had installed as root rather than as myself. So I uninstalled as root, then installed as myself:
所以我以 root 而不是我自己的身份安装。所以我以 root 身份卸载，然后以我自己的身份安装：
sudo gem uninstall bundler
gem install bundler
rbenv rehash
(last command for if you are using rbenv)
（如果您使用 rbenv 的最后一条命令）
And it worked. The "correct" path wasin .bashrc(or other shell profile), at least according to
它奏效了。“正确的”路径是在.bashrc（或其他外壳配置文件），至少根据
$PATH
=> zsh: /Users/myself/.rbenv/shims:/Users/myself/.rbenv/bin: ... etc
but it was expecting it to be installed for myself - not for root. In my case, its rightful installation place is in ~/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/bundler
但它希望它是为我自己安装的——而不是为 root 安装的。就我而言，它的正确安装位置在~/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/bundler

I did this (Ubuntu latest as of March 2013 [ I think :) ]):
我这样做了（Ubuntu 最新的截至 2013 年 3 月 [我认为 :)]）：
sudo gem install bundler

If you need gem, I installed Ruby this way (though this is chronically taxing):
如果您需要 gem，我会以这种方式安装 Ruby（尽管这会长期造成负担）：
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

My solution was to make sure I selected a version of Ruby for that repo.
我的解决方案是确保我为该存储库选择了一个 Ruby 版本。
Example: chruby 2.2.2or rvm use 2.2.2
示例：chruby 2.2.2或rvm use 2.2.2
λ bundle install
zsh: command not found: bundle
λ ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
### Notice the system Ruby version isn't included in chruby
λ chruby
ruby-1.9.3-p551
ruby-2.1.2
ruby-2.2.1
### Select a version via your version manager
λ chruby 1.9.3
### Ensure your version manager properly selects a version (*)
λ chruby
* ruby-1.9.3-p551
ruby-2.1.2
ruby-2.2.1
λ bundle install

Probably distro-proof path is adding this to your .bashrc or .zshrc, whatever your shell is :
无论您的 shell 是什么，可能都是防发行版的路径将它添加到您的 .bashrc 或 .zshrc 中：
PATH="$(ruby -e 'print Gem.default_dir')/bin:$PATH"
or if you have installed your gems user-wide, use :
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"

On my Arch Linux install, gems were installed to the ~/.gem/ruby/2.6.0/bindirectory if installed as user, or /root/.gem/ruby/2.6.0/binif installed via sudo. Just append the appropriate one to your $PATHenvironment variable:
在我的 Arch Linux 安装中，~/.gem/ruby/2.6.0/bin如果以用户身份安装，或者/root/.gem/ruby/2.6.0/bin通过sudo. 只需将适当的附加到您的$PATH环境变量中：
export PATH=$PATH:/home/your_username/.gem/ruby/2.6.0/bin

Step 1:Make sure you are on path actual workspace.For example, workspace/blog $: Step2:Enter the command: gem install bundler. Step 3: You should be all set to bundle install or bundle update by now
第1步：确保你在路径实际工作区。例如，workspace/blog $: Step2：输入命令：gem install bundler。第 3 步：您现在应该都设置为捆绑安装或捆绑更新
