烧瓶调试在 Anaconda 下不起作用

2022-01-10 00:00:00 python flask anaconda

问题描述

我在使用 Flask 的标准开发环境中工作，但无法让调试工作正常进行.

I'm working in a standard development environment with Flask and am having trouble getting the debug to work.

只使用标准的 Hello World，出现如下错误:

Just using the standard Hello World, with an error like so:

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    err
    return "Hello World!"

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

我的应用程序中断，但没有动态调试，我收到以下错误消息:

My application breaks, but there is no dynamic debugging and I get the following error message:

If you enable JavaScript you can also use additional features such as code 
execution (if the evalex feature is enabled), automatic pasting of the 
exceptions and much more.

我启用了 JavaScript，但不知道为什么会收到此错误.有什么想法吗?

I have JavaScript enabled, and don't know why I'm receiving this error. Any ideas?

我在这里找到了类似的帖子.Flask 似乎找不到几个文件.

I found this similar post here. It appears that Flask can't find a few files.

127.0.0.1 - - [23/Feb/2014 22:04:37] "GET /?__debugger__=yes&cmd=resource&f=style.css HTTP/1.1" 404 -

我正在使用 Anaconda 并已删除并重新安装了 Flask 和 Werzeug，但问题仍然存在.

I am using Anaconda and have removed and reinstalled both Flask and Werzeug, but am still having the issue.

解决方案

你也可以卸载 conda 包

You can also uninstall the conda packages

conda remove flask
conda remove werkzeug

然后只需 pip install 这两个

Then just pip install both of those

pip install flask
pip install werkzeug

使用 conda 3.4.2 对我有用

That worked for me using conda 3.4.2
