當我嘗試去安裝 python-memcache的時候就會出現一些奇怪的問題

pip3 install python-memcached

Collecting python-memcached
Using cached python-memcached-1.58.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):

----------------------------------------

Command “python setup.py egg_info” failed with error code 1 in /private/var/folders/lj/lzh02v9s14vbcn90m2qc5x600000gn/T/pip-build-aekw3i_w/python-memcached/

這個報錯資訊雖然比較發雜最後都 出現了索引問題 但是這個問題 真的很常見

解決方法：

pip3.   install --upgrade setuptools
