标签: python cygwin pip simplejson

在Windows 10和64位Cygwin中安装了所有python软件包。然后我使用python -m ensurepip安装了pip。

之后pip install --upgrade simplejson就像这样出错了

$ pip install --upgrade simplejson

simplejson已通过CygWin安装提供,但升级出错了。

答案 0 :(得分:0)

我假设您已经尝试通过安装程序安装simplejson,当您已经通过pip安装它时。这样做会导致问题。

如果您不知道如何手动删除pip版本以及Cygwin版本,我建议您寻求帮助。

OFF主题:(我仍然想知道为什么没有" pip3"在我的Cygwin上并且那个pip安装到2.7,即使在python3下运行。毁了我的Cygwin设置,它有最近没有备份... 叹息现在要清除Python的东西......)
