标签: rubygems

我不使用我在我的机器或我处理的服务器中安装的gems的RI或RDoc输出(我使用其他文档方法).

我安装的每个gem默认安装RI和RDoc文档,因为我忘了设置--no-ri --no-rdoc.

有没有办法让这两个标志成为默认值？

如何从系统中删除RVM(Ruby版本管理器)？

尝试安装gem(gem install mygem)或更新RubyGems(gem update --system)失败,出现此错误:

ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

任何人都知道如何解决这个问题？

我在尝试mysql2为Rails 安装gem 时遇到了一些问题.当我尝试通过运行安装它bundle install或gem install mysql2它给我以下错误:

安装mysql2时出错:错误:无法构建gem原生扩展.

我该如何修复并成功安装mysql2？

我想从最新的GitHub源安装gem.

我该怎么做呢？

我正在使用Fedora 14,我安装并运行了MySQL和MySQL服务器5.1.42.现在我尝试以root用户身份执行此操作:

gem install mysql

但我得到这个错误:

Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h


Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.

这有什么不对？在安装ruby 1.8.7.和最新的rubygems 1.3.7.

对于上下文,它在具有防火墙的远程服务器上.我正在通过代理设置我的环境.我有ruby 1.8.7.当我尝试宝石安装..

sudo gem install --http-proxy <host address>:<port> json

我收到以下错误:

Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h

由于我不确定问题是什么,我用Google搜索并找到了这些

• gem install:无法构建gem原生扩展(找不到头文件) - 这里的说明似乎特定于正在安装的gem.

• 如何安装json gem - 无法构建gem native扩展 这似乎是略有不同的错误.

任何提示？谢谢!

我想要Bundler加载本地gem.那有选择吗？或者我是否必须将gem文件夹移动到.bundle目录中？

如果我将.gem文件下载到计算机中的文件夹,我可以稍后使用它安装gem install吗？

在终端上运行brew命令时出现此错误.需要帮助解决.
