Rails的错误 - '需要'：没有这样的文件加载 - ruby​​gems（LoadError） [英] Rails Error - `require': no such file to load -- rubygems (LoadError)

问题描述

我最近在RVM上安装了一些指令来安装 ruby​​-debug ，我想这可能会导致一些问题。我找到说明的链接在这里： http://beginrescueend.com/support/troubleshooting/

I recently followed some instructions with RVM to install ruby-debug and I think it might have caused some problems. The link that I found the instructions are here: http://beginrescueend.com/support/troubleshooting/

我用来安装的命令如下：

The commands I used to install are the following:

$ rvm reinstall 1.9.3 --patch debug --force-autoconf
$ gem install ruby-debug19 -- --with-ruby-include="${MY_RUBY_HOME/rubies/src}"

现在，当我尝试启动rails服务器时，收到以下错误：

Now, when I try to start the rails server, I receive the following error:

./bundler_stubs/rails:13:in `require': no such file to load -- rubygems (LoadError)
from ./bundler_stubs/rails:13

这个问题会让我相信我安装了多个版本的rails：一个href =https://stackoverflow.com/questions/2896485/no-such-file-to-load-rubygems-loaderror>没有这样的文件加载 - ruby​​gems（LoadError）

This SO question would lead me to believe that I have more than one version of rails installed: no such file to load -- rubygems (LoadError)

然而，当我运行 whic h -a ruby​​ 作为选定的答案建议，我只收到 / usr / bin / ruby​​ 。任何想法在这里做什么？

However, when I run which -a ruby as the selected answer suggests, I only receive /usr/bin/ruby. Any thoughts on what to do here?

推荐答案

在使用它之前，您需要显式激活已安装的Ruby版本。

You need to explicitly activate the installed Ruby version before using it.

rvm use 1.9.3

ruby​​ 现在应该指向新版本。

which ruby should now point to the new version.

您可以使用

You can set a default Ruby version with

rvm --default 1.9.3

另一种选择是在项目文件夹中激活Ruby版本。这可以通过在那里放置一个.rvmrc文件来实现。例如：

Another option is to have that Ruby version activated in your project folder. This can be achieved by placing a .rvmrc file there. E.g.

echo "rvm use 1.9.3" >> /project/folder/.rvmrc

现在您需要安装所有宝石（包括rubygems，rails等等）为特定的（rvm）Ruby版本，例如

Now you will need to install all your gems (including rubygems, rails etc.) for that particular (rvm) Ruby version, e.g.

gem install ruby-debug19
