可以“安装宝石”被配置为在默认情况下在/ usr / bin /之外安装可执行文件？ [英] Can "gem install" be configured to install executables outside /usr/bin/ by default?

问题描述

默认情况下，当 sudo gem install thegemname 时，它会将可执行文件安装到 / usr / bin / p>

有没有办法改变它？例如，要将它们安装到 / usr / local / ruby​​gems / bin （或任何其他路径）？

该路径似乎没有被硬编码到gemspec文件中，所以我不明白为什么这不应该是可能的（尽管我对Ruby / Gems的经验很少）

解决方案

请参阅 http：// www。 rubygems.org/read/chapter/11 并指定一个定义gemhome变量的〜/ .gemrc 。

例如：

  gemhome：/ usr / local / ruby​​gems 
  

您也可以将此文件放置在 / etc / gemrc中

您也可以设置 GEM_HOME env-variable ：

  $ export GEM_HOME = / tmp / gemtest 
 $ gem install bundler 
 $ ls / tmp / gemtest / bin / 
 bundle 
  

By default, when you sudo gem install thegemname it will install executables into /usr/bin/

Is there a way to change this? For example, to install them into /usr/local/rubygems/bin (or any other path)?

The path doesn't seem to be hard-coded into the gemspec file, so I don't see why this shouldn't be possible (although I have very little experience with Ruby/Gems)

解决方案

See http://www.rubygems.org/read/chapter/11 and specify a ~/.gemrc which defines a gemhome variable.

For example:

gemhome: /usr/local/rubygems

You can also place this file in /etc/gemrc

Alternatively you can set the GEM_HOME env-variable:

$ export GEM_HOME=/tmp/gemtest
$ gem install bundler
$ ls /tmp/gemtest/bin/
bundle
