我试图通过pip安装SQLAlchemy。但是,我失败了。
我的操作系统是Windows 10中文版,我使用的是Python 3.6.0。
我在互联网上搜索了我的问题并得到了许多解决方案,我说我可以将sys.setdefaultencoding添加到某个文件中。但是我使用的是Python3。
我还发现issue on Github这似乎是我的问题。但是将我的代码页更改为866或65001根本不起作用......
以下是信息:

打开\ python36 \ lib \ site-packages \ pip \ compat__init __。py 75 return s.decode(' utf_8 ')更改为
返回s.decode(' cp936 ')
其他: chcp cmd显示当前代码页

我解决了这个问题,在“\ python36 \ lib \ site-packages \ pip \ compat__init __。py”中更改了75行(感谢之前的评论)
return s.decode('latin1')
。
