Question

在提出这个问题之前，我搜索了SO，找到了几个相关的链接：UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 13: ordinal not in range(128), regarding reading in files

但它们对我的帖子没有用，所有这些都是关于程序的，但我的是用于安装。

安装点子后，查看点子列表：

C:\Users\中jin>pip list
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
pip (9.0.1)
setuptools (28.8.0)

当我安装django使用pip时，我收到了以下错误：

C:\Users\中jin>pip install django
Collecting django

我在Windows10和python 2.7。

Answer 1

我怀疑您的临时目录在实际路径中包含非ASCII 7位字符。

如果您在Windows上，请确保将环境变量％TEMP％设置为仅使用其完整路径的目录，A-Za-z0-9范围内的值不带重音字符，符号等等。

注意

在Windows 10和python 2.7.13上，我刚刚测试并得到了：
