通过gem install mechanize安装gem时显示错误"RUBYOPT中的无效切换:-F(RuntimeError)"

Question

我试图通过以下命令在我的计算机上安装gem(mechanize):

>> gem install mechanize --platform=ruby
>> gem install mechanize

错误

ERROR:  Error installing mechanize:
        ERROR: Failed to build gem native extension.

    "C:/Program Files/Ruby200-x64/bin/ruby.exe" extconf.rb
C:/Program Files/Ruby200-x64/bin/ruby.exe: invalid switch in RUBYOPT: -F (RuntimeError)

在我尝试安装宝石时显示(机械化).并以管理员身份运行命令行.

我通过以下命令安装了DevKit(config.xml已经修改了原因)

ruby dk.rb init
ruby dk.rb install

有没有什么方法可以解决这个错误？提前致谢.

这里有一些OS信息:

• 操作系统版本:Win7 64位
• Ruby版本:2.0.0p195 x64
• DevKit版本:DevKit-mingw64-64-4.7.2-20130224-1432-sfx
• GEM版本:2.0.3
• Ruby安装位置:C:/ Program Files/Ruby200-x64

根据故障排除,我将从Regedit(HKCU\Software\Microsoft\Command Processor)中删除AutoRun ,但它仍然无法正常工作!

Answer 1

我找到了原因.只是因为Ruby的安装路径中有一个空格

RUBY EXECUTABLE: "C:/Program Files/Ruby200-x64/bin/ruby.exe"

将Ruby重新安装到不包含空格的路径,将修复此错误.

当然,AutoRun应该从HKCU\Software\Microsoft\Command Processor和中删除HKLM\Software\Microsoft\Command Processor.

那很重要!
