卸载后无法安装可可豆荚，导致错误 [英] Cannot install cocoa pods after uninstalling, results in error

问题描述

我删除了可可豆荚，因为它声称它已安装，但一直说未找到命令包。当试图重新安装cocoapods（ sudo gem install cocoa pods -v ）时出现此错误：

I removed cocoa pods because it claimed it had installed, but kept saying the command pod wasn't found afterward. When trying to reinstall cocoapods (sudo gem install cocoa pods -v) I get this error:

错误：执行gem时...（Errno :: EPERM）
不允许操作 - / usr / bin / pod

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

任何想法？

推荐答案

正如Ramesh Ramchandaran在下面指出的那样，这是一种更清洁的方式，而不是获取围绕OS X的安全功能。

As it has been pointed out below by Ramesh Ramchandaran, this is a cleaner way of doing it, instead of getting around the Security features of OS X.

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

原始答案

我假设你正在运行OS X 10.11。

Original Answer

I'm assuming you're running OS X 10.11.

这种情况正在发生，因为Apple已经在新安装上启用了rootless。

This is happening because Apple has enabled rootless on the new install.

如果是ou类型：

sudo nvram boot-args="rootless=0"; sudo reboot

在 terminal.app 中，你的计算机将在禁用时重启。

in terminal.app, your computer will reboot with it disabled.

完成后，输入：

sudo gem install cocoapods -V

-V 用于详细，如果发生任何错误，将吐出。

the -V is for verbose and will spit out any errors if they happen.
