使用Ruby企业版，gem没有安装在我所期望的地方 [英] Using Ruby Enterprise Edition, gems are not installed where I would expect

问题描述

我刚刚安装了Ruby Enterprise Edition，并为它安装了一些宝石。股票Ruby 1.8.6也安装在服务器上。

我添加了 /opt/ruby-enterprise-1.8.6-20090201/bin 到我的 PATH / usr / bin 的头部，其中 ruby 和 gem live。

code>证实了这一点：

/opt/ruby-enterprise-1.8.6-20090201/bin/gem



gem install some_gem

它们最终位于 /usr/lib/ruby/gems/1.8/gems / 而不是 /opt/ruby-enterprise-1.8.6-20090201/lib/ruby/gems/1.8/gems / 。

但是如果我使用 /opt/ruby-enterprise-1.8.6-20090201/bin/gem install some_gem 它 进入REE的gem目录。

我不明白。有一些配置选项，我必须改变？我 在这里使用sudo。也许这跟它有关系？

解决方案

这里有一个很好的解释：

sudo变更PATH - 为什么？

这里假设你使用的是Ubuntu。 sudo确实改变了ubuntu下的路径。

/ usr / bin /中的gem可能是/usr/bin/gem1.8的符号链接。我做的是符号链接ruby-enterprise的gem到/ usr / bin / ree-gem，像这样：

sudo ln -s /opt/ruby-enterprise-1.8.6 -20090201 / bin / gem / usr / bin / ree-gem

然后我只用：

sudo ree-gem安装some_gem

专门为ree安装gem。如果你没有使用ruby 1.8.6 ruby​​gem，你可以将REE的gem链接到/ usr / bin / gem中： -enterprise-1.8.6-20090201 / bin / gem / usr / bin / gem

I have just installed Ruby Enterprise Edition and am installing some gems for it. Stock Ruby 1.8.6 is also installed on the server.

I have added /opt/ruby-enterprise-1.8.6-20090201/bin to my PATH a head of /usr/bin where ruby and gem live.

which gem confirms this:

/opt/ruby-enterprise-1.8.6-20090201/bin/gem

However, when I install gems like this:

gem install some_gem

They end up in /usr/lib/ruby/gems/1.8/gems/ instead of /opt/ruby-enterprise-1.8.6-20090201/lib/ruby/gems/1.8/gems/.

But if I use /opt/ruby-enterprise-1.8.6-20090201/bin/gem install some_gem it does go into REE's gem directory.

I don't get it. Is there some config option I have to change? I am using sudo here. Maybe that has something to do with it?

解决方案

There's a good explanation of what's going on here:

sudo changes PATH - why?

This assumes you're using Ubuntu. sudo does change the path under ubuntu.

The gem you have in /usr/bin/ is probably a symlink to /usr/bin/gem1.8. What I did was symlink ruby-enterprise's gem to /usr/bin/ree-gem like this:

sudo ln -s /opt/ruby-enterprise-1.8.6-20090201/bin/gem /usr/bin/ree-gem

then I just use:

sudo ree-gem install some_gem

to install gems specifically for ree. If you're not using the ruby 1.8.6 rubygem, you can symlink REE's gem to /usr/bin/gem instead:

sudo ln -s /opt/ruby-enterprise-1.8.6-20090201/bin/gem /usr/bin/gem
