Python pip安装问题-安装Twilio时出现回溯错误

Question

我尝试使用pip install twilio，也尝试使用$sudo pip install twilio，但一直收到以下错误，在其他地方找不到解决方案，请帮助：

Answer 1

重新安装python：

brew install python

然后尝试：

pip install twilio or sudo pip install twilio

Answer 2

我想通了。显然，我在Mac附带的默认Python2.7上安装了Python3.6。所以每次当我在Python3中安装pip时，当我执行pip install twilio时，它会查找默认的2.7库。所以我可以通过运行以下命令来解决这个问题：

Python3 pip install twilio
