CocoaPod升级(以及ERROR: While executing gem ... (Errno::EPERM)解决办法)

最近pods  0.39.0 升级1.1.1  ,发现一个坑,好纠结,好歹最后解决了

过程如下:

本来我想直接执行:

$ sudo gem install cocoapods   // 安装cocoapods

遇到一个错误:

ERROR:  While executing gem ... (Errno::EPERM)

Operation not permitted - /usr/bin/pod

卧槽,这什么鬼?然后就找解决办法,各种升级命令都不行,无奈之下,就采取先卸载再安装了!

======================正文======================

卸载Pod:

step1:

which pod:

查看pod命令所在路径,比如为/usr/local/bin/pod,

然后执行

rm -rf /usr/local/bin/pod

将pod命令移除

step2:

执行

gem list | grep cocoapods

查看所有与cocoapods相关的已安装的组件,

然后挨个卸载

我这里的执行结果是:

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)

然后我就挨个执行:

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: 重新安装pod

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

所以,在命令中我们必须指定安装到/usr/bin/pods下,这样就可正常安装成功:

执行:

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

安装成功

step4: 查看新安装的pod版本:

pod --version

1.1.1
