解析多个版本的rubygems

概述我有什么看起来像我的机器上安装的多个版本的 rubygems,当我的宝石列表我看到我的所有宝石,但当我去运行脚本,我收到错误消息,如 Missing these required gems: SystemTimer 是否有任何方法可以删除所有版本的rubygems而不是一个？理想情况下,我希望能够访问我的程序中出现在宝石列表下的所有宝石. 来自宝石环境        – RUBY EXECUT 我有什么看起来像我的机器上安装的多个版本的 rubygems,当我的宝石列表我看到我的所有宝石,但当我去运行脚本,我收到错误消息,如

Missing these required gems:  SystemTimer

是否有任何方法可以删除所有版本的rubygems而不是一个？理想情况下,我希望能够访问我的程序中出现在宝石列表下的所有宝石.

如果我跑：

请注意上面我手动调用ruby ** / System / library / Frameworks / Ruby.framework / Versions / 1.8 /usr/bin/ruby​​ **这是我的/usr/bin/ruby​​符号链接到的文件,我的GEM_PATH也设置为/System/library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8

@R_502_6120@ 我觉得你可能使用的不同版本的ruby比ruby宝石更多.无论是ruby还是ruby都不知道在哪里寻找你的宝石.

请参阅gem installation guide以确保您的环境配置为使用gem.

如果您在按照说明 *** 作后仍然遇到问题,请确保您没有安装多个版本的ruby.如果有多个版本的Ruby可用,请确保您的脚本调用与gem相同的Ruby版本.这是通过将RUBY_EXECUtable的gem环境列表与脚本的shebang行进行比较来完成的.仔细检查以遵循任何符号链接,因为大多数基于分发的ruby安装会将/usr/bin/ruby​​符号链接到/usr/bin/ruby1.8

您还应该检查您的gem是否由运行该脚本的同一用户安装.

如果您在没有root权限的情况下运行gem install,则新gem将安装在您的主目录中.如果您正在运行依赖于这些gem作为另一个用户的脚本.那些已安装的宝石将无法找到.但是,如果您的gem由root用户安装并且另一个用户正在运行需要这些gem的脚本,则没有问题.

我从Ruby转向Ruby Enterprise Edition时遇到了这个问题.我发现我必须使用REE的gem实例再次安装我所需的所有宝石.
