安裝Pod時提示ERROR: While executing gem ... (Errno::EPERM) Operation not permitted - /usr/bin/pod

環境：OSX EI 10.11.1

昨天切換gem源后，招待pod安裝沒有任何問題，也可以正常用
$ gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/
$ sudo gem install cocoapods

今天再使用的時候，在一個項目下執行pod install時半天死活沒反應，無奈就ctrl+c了強制退出了。然后再執行的時候就出現錯誤：

Library/Ruby/Site/2.0.0/rubygems/dependency.rb:318:in `to_specs': Could not find 'cocoapods' (>= 0) among 33 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/xianlong/.gem/ruby/2.0.0:/Library/Ruby/Gems/2.0.0:/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/gems/2.0.0', execute `gem env` for more information
from /Library/Ruby/Site/2.0.0/rubygems/dependency.rb:327:in `to_spec'
from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_gem.rb:64:in `gem'
from /usr/local/bin/pod:22:in `<main>'

 

分析可能是因為強制退出程序導致的配置被損壞。於是把pod卸載，重新安裝后就ok了。

卸載Pod:

step1:

which pod: 查看pod命令所在路徑,比如為/usr/local/bin/pod，然后執行 rm -rf /usr/local/bin/pod 將pod命令移除

 

step2:

執行gem list | grep cocoapods  查看所有與cocoapods相關的已安裝的組件，然后挨個卸載

我這里的執行結果是：

cocoapods-core (0.39.0)

cocoapods-downloader (0.9.3)

cocoapods-plugins (0.4.2)

cocoapods-search (0.1.0)

cocoapods-stats (0.6.2)

cocoapods-trunk (0.6.4)

cocoapods-try (0.5.1)

 

然后我就挨個執行：

gem uninstall cocoapods-core

gem uninstall cocoapods-downloader

gem uninstall cocoapods-plugins

gem uninstall cocoapods-search

gem uninstall cocoapods-stats

gem uninstall cocoapods-trunk

gem uninstall cocoapods-try

 

step3: 重新安裝pod

執行sudo gem install cocoapods， 提示出錯：While executing gem ... (Errno::EPERM)     Operation not permitted - /usr/bin/pod

在命令中指定安裝到/usr/bin/pods下即可正常安裝成功：

sudo gem install -n /usr/local/bin  cocoapods 

安裝成功，

 

step4: 查看新安裝的pod版本：

pod --version

0.39.0
