Flask:ModuleNotFoundError:没有名为“SocketServer”的模块

Question

我有一个奇怪的错误，我以前从未见过

我使用flask编写了一个小型http web服务器，当我运行时，出现了下面的错误

我使用的是虚拟环境，我的python版本是3.8

可能是什么

from flask import Flask, request

app = Flask(__name__)


@app.route("/")
def index():
    print(request.get_json())


if __name__ == "__main__":
    app.run(debug=True)

python tools/fake.pyTraceback (most recent call last):
  File "/home/ubuntu/workspace/otc/venv/lib/python3.8/site-packages/werkzeug/serving.py", line 58, in <module>
    from http.server import BaseHTTPRequestHandler
ModuleNotFoundError: No module named 'http.server'; 'http' is not a package

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "tools/fake.py", line 1, in <module>
    from flask import Flask, request

    import SocketServer as socketserver
ModuleNotFoundError: No module named 'SocketServer'```

Answer 1

这也许对你有帮助 `

pip uninstall Flask

pip uninstall Werkzeug

pip install Flask

pip install Werkzeug

`

Answer 2

问题来自第一次回溯：

ModuleNotFoundError: No module named 'http.server'; 'http' is not a package

您需要将http.py文件重命名为其他文件，因为它正在重写标准库http模块。要修复它，您需要执行以下操作：

• 将文件http.py重命名为其他文件
• 删除项目中的.pyc文件

find . -name "*.pyc" -delete

• 再次运行程序

Python3使用socketserver，全部小写。Python2使用SocketServer
