我正在尝试使用 Brython 在 python 中导入PSAW库，我有以下代码：

<!DOCTYPE html>
<html>

    <head>
        <script type="text/javascript" src="brython.js"></script>
        <script type="text/javascript" src="brython_stdlib.js"></script>
    </head>

    <body onload="brython()">

        <script type="text/python">
        from browser import document
        document <= "Hello world !"
        </script>

    </body>
</html>

这可以正常工作，但是当我像这样添加 PSAW 时：

<!DOCTYPE html>
<html>

    <head>
        <script type="text/javascript" src="brython.js"></script>
        <script type="text/javascript" src="brython_stdlib.js"></script>
    </head>

    <body onload="brython()">

        <script type="text/python">
        from browser import document
        import PushshiftAPI
        document <= "Hello world !"
        </script>

    </body>
</html>

我在chrome中收到以下错误：

GET http://localhost:8000/requests.py?v=1571453029466 404 (File not found)
Error 404 means that Python module requests was not found at url http://localhost:8000/requests.py

Traceback (most recent call last):
ImportError: No module named requests

我认为这意味着它需要 Brython 无法找到的其他模块，但我不确定如何确定需要哪些模块以及如何正确添加它们。这是我的文件目录：

更新：

我在虚拟环境中安装了 PSAW 和 PRAW 并将所有包复制到目录中，如下所示：

但是，尝试导入请求时我仍然收到以下问题

Traceback (most recent call last):
AttributeError: 'NoneType' object has no attribute 'load_module'

    at method (brython.js:5321)

知道这里发生了什么吗？

404 错误表示“找不到文件”。您的浏览器正在尝试访问位于“ http://localhost:8000/requests/__init__.py?v=1571453029904 ”（以及回溯中的其他位置）的库，但找不到它。尝试在浏览器中访问 URL。它会返回一个文件吗？如果在那里找不到文件，Brython 也无法找到。尝试重新排列您的文件系统，直到您可以在浏览器中访问 .py 文件
