如何解决此问题(在Windows中)?
答案 0 :(得分:3)
如果你收到像pip这样的错误:错误:没有这样的选项: - hash,你使用的Pip版本太旧了,请使用以下命令进行升级:
$ pip install --upgrade pip
在Windows上,推荐的命令是:
python -m pip install --upgrade pip
更新后,如果再次出现此错误, 使用" - no-cache-dir "升级/安装时:
pip --no-cache-dir install YOUR-PACKAGENAME
或
pip --no-cache-dir install --upgrade YOUR-PACKAGENAME
散列不同的一个很好的理由是,如果您使用现有散列未涵盖的平台,则可以使用带有轮子的包。
