提问by bigpotato

Hi I've been having a probably trying to install the Ruby gem bundle. I follow the directions gem install bundleafter I receive this message, but it still doesn't work when I type bundle -v. I also type

嗨，我一直在尝试安装 Ruby gem 包。gem install bundle收到此消息后，我按照说明进行操作，但是当我输入bundle -v. 我也打字

which bundleand receive

which bundle并接收

/Users/edmundmai/.rvm/bin/bundle

so it exists!! So why does it not work!! Is there something wrong with the mysterious $PATH that I don't get? (I'm a noob).

所以它存在！！那么为什么它不起作用！！我不明白的神秘 $PATH 有什么问题吗？（我是菜鸟）。

Here's my .bash_profile:

这是我的 .bash_profile：

PATH=$PATH:~/bin
export PATH
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

Here's my .bashrc :

这是我的 .bashrc ：

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" 

Here's my gem env:

这是我的宝石环境：

UPDATE So after trying to go through the RoR tutorial again, I repeated a few of the steps from earlier in the chapter in one of my two terminal windows (let's call them Terminal #1 and Terminal #2). Terminal #2 still doesn't work (the command line isn't on any directory, just the default directory) while Terminal #1 (at my sample_app directory) works. I think rvm get head && rvm reloadmight be the key? But does that mean I have to run that every time I open my terminal? Check out my terminal #1 commands for before and after (I deleted some of the output so that it would be more clear what my input lines were):

更新 因此，在再次尝试阅读 RoR 教程之后，我在我的两个终端窗口之一（让我们称它们为终端 #1 和终端 #2）中重复了本章前面的一些步骤。终端 #2 仍然无法工作（命令行不在任何目录中，只是默认目录）而终端 #1（在我的 sample_app 目录中）工作。我想rvm get head && rvm reload可能是关键？但这是否意味着我每次打开终端时都必须运行它？查看我的终端 #1 之前和之后的命令（我删除了一些输出，以便更清楚我的输入行是什么）：

I'm extremely unclear as to what the $PATH does. If you guys need any more info, feel free to tell me and I'll provide it.

我非常不清楚 $PATH 的作用。如果你们需要更多信息，请随时告诉我，我会提供。

I think this is the problem: You have bundler installed to a specific gemset, which is why it's only available when you're in your app's directory (I'm assuming there's a .rvmrcfile in there).

我认为这是问题所在：您已将 bundler 安装到特定的gemset，这就是为什么它仅在您位于应用程序目录中时才可用（我假设那里有一个.rvmrc文件）。

You have a few options:

您有几个选择：

1. Install bundlerto a global gemset. rvm gemset use global && gem install bundler
2. If you have Homebrew installed, just do brew install rubyand avoid rvm altogether. (There's also rbenv and ry as alternatives to rvm, but I just use 1.9.3 across all my apps, so Homebrew is fine.)

1. 安装bundler到全局 gemset。rvm gemset use global && gem install bundler
2. 如果您安装了 Homebrew，请brew install ruby完全避免使用 rvm。（还有 rbenv 和 ry 作为 rvm 的替代品，但我只在所有应用程序中使用 1.9.3，所以 Homebrew 很好。）

For reference, $PATHis a shell environmental variable containing a list of directories that hold executables (e.g., echo, ls, vim, etc.). It's intrinsic to shells.

作为参考，$PATH是包含目录的列表，保持可执行文件（例如，壳环境变量echo，ls，vim等等）。它是贝壳的固有特性。

Sometimes it is just that you are not sourcing rvm correctly, because you are not in a login shell (using screen?). Type

有时只是您没有正确采购 rvm，因为您不在登录 shell 中（使用屏幕？）。类型

    source ~/.rvm/scripts/rvm

And use any bundle command.

并使用任何 bundle 命令。

Add the following line to ~/.bashrcfile

将以下行添加到~/.bashrc文件

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

then reload the file:

然后重新加载文件：

$ source ~/.bashrc

Even i had same problem,

即使我有同样的问题，

In server rvm was not selected as default.So

在服务器 rvm 中没有选择为默认值。所以

rvm use 1.9.3 --default

gem install bundler

solved my problem

解决了我的问题

(Problem occurs only when using rvm)

（只有使用rvm时才会出现问题）

回答by Eric Brooke

If you are using rvm create a separate gemset, which are self-contained bundles of gems.

如果您使用 rvm，请创建一个单独的 gemset，它们是自包含的 gem 包。

rvm use 1.9.3@myApplicationNameHere --create --default

• myApplicationNameHere = change this to your application name
• create = creates a gemset
• default = means use this version of ruby and gemset as default

• myApplicationNameHere = 将此更改为您的应用程序名称
• create = 创建一个 gemset
• default = 表示使用这个版本的 ruby​​ 和 gemset 作为默认值
