windws 10 下升级 pip ,升级时下载安装包,卸载原有pip成功,在安装新pip包时因种种原因安装失败会导致pip被卸载,本文记录修复方法 。

常见原因

  • Windows 中anaconda文件夹没有为users用户开放全部控制权限
  • 在更新pip时命令为(这是错误的命令):
1
pip install -U pip

此时pip从服务器下载了最新的pip安装包,卸载了原来的pip,但是没有权限安装新的pip

导致使用此命令更新pip后无pip可用

正确命令shell

  • 在选项中加入 --user
1
pip install --upgrade pip --user

修复命令

1
2
