pip说我会考虑升级。当我这样做并使用

时

python -m pip install --upgrade pip

我收到以下UnicodeDecode错误消息：

You are using pip version 7.1.2, however version 8.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

我在Windows 10计算机上运行32位版本的Python 3。我不知道这是否与它有任何关系，但我在我的系统上安装了VisualStudio，版本10。现在它已被删除。

亲切的问候约翰

Answer 1

感谢blackpingus，你的回答帮助我找到了问题。

问题是'ö'字符，这是我在Windows上使用的名称。因此，此名称也放在系统路径中。

该问题的解决方法是使用另一个用户帐户安装该软件包，该帐户的名称中没有任何“变性”。

从头开始，找到＆＃34;命令提示符
右键单击＆＃34;命令提示符＆＃34;
以管理员身份运行
提示时提供用户名和密码
现在你可以升级pip：python -m pip install --upgrade pip
