安裝cocoapods(踩坑)

今天安裝cocoapods遇到一些坑：

ERROR: Error installing cocoapods: activesupport requires Ruby version >= 2.2

在網上搜集到的解決辦法：

1.移除現有的Ruby

gem sources –remove https://rubygems.org/

2.使用淘寶鏡像

gem sources -a https://ruby.taobao.org/

3.驗證當前ruby版本

gem sources -l

成功後提示：

* CURRENT SOURCES *
https://ruby.taobao.org/

4.開始安裝cocoapods

sudo gem install cocoapods

這時候提示：

Fetching: i18n-0.7.0.gem (100%)

Successfully installed i18n-0.7.0

Fetching: thread_safe-0.3.5.gem (100%)

Fetching: activesupport-5.0.0.gem (100%)

ERROR: Error installing cocoapods:

activesupport requires Ruby version >= 2.2.2.

這個地方很坑，以前安裝cocoapods一直是沒有這個問題的，這裏提示Ruby版本要大於或等於2.2.2

因而查看ruby版本：

ruby -v

ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]

果真這裏就要升級Ruby版本啦

查看目前的全部ruby版本：

rvm list known

若是提示command not found 請先安裝rvm

curl -L get.rvm.io | bash -s stable

若是已安裝會列出全部的ruby版本：

這裏咱們安裝2.2.2:

rvm install 2.2.2

終端運行結果：（若是直接成功請繞過homebrew的卸載安裝）

回車：

It appears Homebrew is already installed. If your intent is to reinstall you should do the following before running this installer again:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

The current contents of /usr/local are .git Requirements installation failed with status: 1.

這裏執行：

ruby -e 「$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)」

卸載home-brew

這樣ruby2.2.2就安裝好了

如今就能夠安裝cocoapods啦：

sudo gem install cocoapods

看看這樣cocoapods就安裝成功了
