我尝试使用pip install twilio，也尝试使用$sudo pip install twilio，一直出现以下错误，在其他地方找不到解决方案，请帮助：

你的操作系统是什么？
@Zcode Mac OS Sierra 10.12.5

标签： python python-2.7 python-3.x pip

【解决方案1】：

再次安装python：

brew install python

然后尝试：

pip install twilio or sudo pip install twilio

【解决方案2】：

想通了。显然，我在 Mac OS 附带的默认 Python 2.7 之上安装了 Python 3.6。所以每次我做pip install twilio 时，它都会在 Python3 中安装 pip 时查看默认的 2.7 库。所以我能够通过运行来解决它：

Python3 pip install twilio
