Gem安装在windows上失败。mkmf.log找不到-lX11

Question

我正在尝试为我的rails框架安装rmagick gem。我已经安装了imagemagick，并在系统变量中设置了lib和include path

但在安装gem install rmagick -- '--with-opt-dir="c:\RailsInstaller\ImageMagick-6.7.9-Q8"‘时，我仍然收到错误。

gem命令

C:\sites\redmine> gem install rmagick -- '--with-opt-dir="c:\RailsInstaller\ImageMagick-6.7.9-Q8"'
gem.bat : ERROR:  While executing gem ... (OptionParser::InvalidOption)
At line:1 char:4
+ gem <<<<  install rmagick -- '--with-opt-dir="c:\RailsInstaller\ImageMagick-6
.7.9-Q8"'
    + CategoryInfo          : NotSpecified: (ERROR:  While e...:InvalidOption) 
   :String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

    invalid option: --with-opt-dir=c:\RailsInstaller\ImageMagick-6.7.9-Q8

mkmf.log文件说

从日志中可以看出，devkit无法定位ImageMagick，但我已经将其设置为PATH = C:\RailsInstaller\ImageMagick-6.7.9-Q8

Answer 1

你有没有考虑过用nitrous io进行开发？在windows中开发rails要困难得多，因为有许多错误你必须处理，而其他人不需要处理，而且也没有太多的文档/支持。大多数答案可以归结为"windows和rails不能混合“。
