Problem resolution Cocoapods not working correctly after MAC OS upgrade to 10.11 (OS X eicaption)

Went home last night after the upgrade system to 10.11, downloaded a whole night after finally downloaded in the morning, brought to the company in the morning, want to check a third-party library, but encountered a problem:

guoyufudeMacBook-Pro:~ GuoYufu$ pod search VKVideoPlayer
-bash: pod: command not found

Then try:

guoyufudeMacBook-Pro:~ GuoYufu$ gem sources -l
*** CURRENT SOURCES ***

http://ruby.taobao.org/

This is true.

Continue to try:

guoyufudeMacBook-Pro:~ GuoYufu$ pods help
-bash: pods: command not found

It is then basically determined that the system upgrade causes cocoapods not to function properly. Continue to find the solution:

1. First consider reinstalling the Cocoapods:

guoyufudeMacBook-Pro:~ GuoYufu$ sudo gem install cocoapods
Password:
ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/pod

Failed.

2. Continue to find the solution according to the error information, run the found:

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

Tips:

Successfully installed cocoapods-0.38.2
Parsing documentation for cocoapods-0.38.2
1 gem installed

Did it succeed?

Try:

Pod Search Vkvideoplayer

can be performed normally.

Try to update the version of Cocoapods:

guoyufudeMacBook-Pro:~ GuoYufu$ sudo gem install cocoapods
Password:
ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/pod

or an error.

3. Simply follow the initial steps to install it all over again:

Brew Install Ruby

sudo gem install Cocoapods

Finally no more error.
