sudo easy_install pip ImportError: No module named extern Mac OS X

在 Mac OS X 裡,預設沒有 pip 指令可以使用。

執行 sudo easy_install pip 結果:

Traceback (most recent call last):
 File "/usr/local/bin/easy_install", line 11, in <module>
 load_entry_point('setuptools==33.1.1', 'console_scripts', 'easy_install')()

ImportError: No module named extern

改執行 brew install python

結果是:

Warning: python 2.7.13_1 is already installed

解法:

https://pip.readthedocs.io/en/stable/installing/

先執行 :

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

 

再執行

sudo python get-pip.py

 

就有 pip 指令可以用了。
