I am trying to install gem (mechanize) on my computer by running the following commands:
>> gem install mechanize --platform=ruby >> gem install mechanize
Error
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)
displayed when I try to set gems (mechanize). And run the command prompt as Administrator .
I installed DevKit using the commands below (config.xml was changed due to a reason)
ruby dk.rb init ruby dk.rb install
Is there any way to fix this error? Thanks in advance.
Here is the OS information:
- OS Version: Win7 64bit
- Ruby version: 2.0.0p195 x64
- DevKit Version: DevKit-mingw64-64-4.7.2-20130224-1432-sfx

According to Troubleshooting , I will remove AutoRun from Regedit ( HKCU \ Software \ Microsoft \ Command Processor ), but it still cannot work!
