pip安装Python包出现错误是可能是系统没有更新或者出现了bug。
解决方法:
在unix和macos,配置文件为:$HOME/.pip/pip.conf,在windows上,配置文件为:%HOME%\pip\pip.ini。
把所有要安装的包写在一个文件里面,比如requirement.txt(每个包写一行,顶行头写),然后pip安装的时候只需要加参数“-r requirement.txt”即可。
进入目录下使用命令:virtualenv env。
source env/bin/activate,这时候你会发现命令行前面会多出个(env)标识,这表明你已经进入了虚拟环境了。
写个简单的hello.py验证:#!/usr/bin/pythonfrom flask import Flaskapp = Flask(__name__)
@app.route('/', methods = ['GET', 'POST'])def hello():return 'Hello world!'if __name__ == '__main__':app.run(),就可以了。

这是python3.4吗?
网上找到的是要替换文件D:\Program Files\Anaconda3\lib\site-packages\pip\_vendor\pkg_resources\__init__.py
你先把这个文件备份一下,然后用这个网页下的文件进行替换
https://bitbucket.org/minrk/setuptools/src/e7d8f68ea7c603638562cf8278daa5d16e699f4e/pkg_resources/__init__.py
不过我还没实践过,楼主小心点测试吧。

这个应该是pip版本和python版本兼容造成的,你可以升级下pip,或者升级下python。
