pip 安装模块失败问题

问题1:

ERROR: Could not find a version that satisfies the requirement xlwt (from vers

ions: none)

ERROR: No matching distribution found for xlwt

原因:网络问题或者是pip版本需要更新

pip升级:python -m pip install --upgrade pip

网络问题更换金镜像源:pip install https://pypi.tuna.tsinghua.edu.cn/simple 模块名

按照上述操作后,出现了问题2

报错: ERROR: Cannot unpack file c:usersadmini~1appdatalocal emppip-unpack-uwt0

assimple (downloaded from c:usersadmini~1appdatalocal emppip-req-build-7m

zbzm, content-type: text/html; charset=utf-8); cannot detect archive format

ERROR: Cannot determine archive format of c:usersadmini~1appdatalocal empp

ip-req-build-7mzbzm

使用以下命令安装成功:pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn 模块名
