在Windows上安装GDAL的问题。无法更新pip

我在Windows10上运行Python 2.7（ArcGIS提供的默认版本）和Python 3.5。我一直在尝试使用二进制安装GDAL，但我不断收到以下错误：在Windows上安装GDAL的问题。无法更新pip

Complete output from command python setup.py egg_info:

You should consider upgrading via the 'python -m pip install --upgrade pip' command.

然后我尝试更新的点子，这是我成功的2.7版本做了，但是当我尝试做3.5版本我收到以下错误相同的过程：

我一直在寻找很多网站和论坛的答案，我很确定造成这个错误的是我用户名中的e的特殊字符。有没有办法运行安装代码，使编码“错误”得到纠正？最明显的方法是更改我的用户文件夹的名称，但这很可能对PC有害。

如果我的假设是错误的，还有什么可能导致这个问题？

而不是复杂化，Python被卸载，然后重新安装在主驱动器中的独占目录。
