ERROR: Loading command: install (LoadError)

安裝gem install bundler的時候提示報錯

ERROR:  Loading command: install (LoadError)
    no such file to load -- zlib
ERROR:  While executing gem ... (NameError)
    uninitialized constant Gem::Commands::InstallCommand

 

根據提示是缺少了zlib庫

然後安裝yum install zlib*

再次運行gem install bundler  還是報錯

原來ruby有自身提供的zlib包

進入ruby目錄

然後在

cd ext/zlib

ruby ./extconf.rb

make

make install

 

再次運行gem install bundler  

ok
