我对尝试让Flask运行感到非常沮丧。我尝试过安装多种方式，但无论如何，我都会遇到一些问题，而不知道如何或为什么。
下面是一个搞乱的示例。这是我的参考：http://flask.pocoo.org/docs/quickstart/

答案 0 :(得分：4)
正如错误所说 - 你的hello.py代码中有一个非ASCII字符，但你还没有声明编码。您可以通过在声明编码的第一行或第二行中为源代码添加注释来解决此问题。例如，如果您的文件以UTF-8保存：
# coding: utf-8
有关详细信息，请参阅PEP 0263。

尝试使用python的easy_install
$python easy_install Flask
