Cocopods的卸载与重新安装

前段时间用HomeBrew把Cocopods升级到 1.0.0.beta.3，今天在项目中执行 pod update 时提示了错误。

{% highlight java %} [!] Invalid Podfile file: [!] The specification of link_with in the Podfile is now unsupported, please use target blocks instead.. {% endhighlight %} 查找的结果是版本太高，所以需要降低Cocoapods的版本来解决第三方库的兼容问题。

• 移除pod组件

{% highlight shell %} $ which pod // 查看安装path，输出/usr/local/bin/pod $ sudo rm -rf /usr/local/bin/pod // 移除安装包 {% endhighlight %}

• 移除 RubyGems 中的 Cocoapods程序包

查看gems本地程序包 {% highlight shell %} $ gem list {% endhighlight %} 输出 {% highlight shell %} *** LOCAL GEMS ***
