Python Can'；t在windows上升级pip

我是python和包管理系统pip的新手。我已经在Windows7上安装了Python2.7.10，并检查了它包含的pip版本-PIP7.0.1。我决定升级pip并进入

python -m pip install -U pip

但我有这个错误

我试着进去

pip install --upgrade pip

但是我得到了相同的结果。

您的windows用户名是否包含非ascii字符

如果是这样，您需要从exe安装pip，或者更改用户

您的系统上是否安装了python 3？请尝试卸载，然后安装。我找到了解决方案。你很接近。我的windows用户名不包含非ascii字符，但我的计算机名包含非ascii字符。这就是原因
