我正在尝试安装tweepy（扩展名为oauthlib），在尝试安装时出现以下错误：
Collecting requests-oauthlib>=0.4.1 (from tweepy)
Using cached requests_oauthlib-0.7.0-py2.py3-none-any.whl
Collecting oauthlib>=0.6.2 (from requests-oauthlib>=0.4.1->tweepy)
Using cached oauthlib-2.0.0.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):

AttributeError: module 'pkg_resources' has no attribute 'safe_name'
有趣的是，
/private/var/folders/t7/751h0y1102z99ysr6659yjcr0000gn/T/pip-build-aoklhwtw/oauthlib/文件夹不存在，所以我可以甚至都不要删除它/仔细看看。
你知道是什么引起的吗？
最佳答案
找到了解决办法。我不得不升级setuptools，所以：
$ sudo pip3 install --upgrade setuptools
