Flask 交互式调试器损坏

问题描述

我想弄清楚为什么 Flask 交互式调试器不工作.我的模板应用程序是准系统，只有一个错误:

I'm trying to figure out why the Flask interactive debugger isn't working. My template application is barebones, with a single error:

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    print missing_variable #Error
    return 'Hello World!'

if __name__ == '__main__':
    app.run(host='0.0.0.0', debug=True)

但是调试器捕获了错误，但给了我一个非交互式页面并抱怨缺少 Javascript:

But the debugger catches the error, but gives me a non-interactive page and complains about a lack of Javascript:

调试器在您的 WSGI 应用程序中捕获到异常.您现在可以查看导致错误的回溯.如果您启用 JavaScript，您还可以使用其他功能，例如代码执行(如果启用了 evalex 功能)、自动粘贴异常等等.

我没有禁用 Javascript，所以我不确定为什么交互式调试器坏了.谢谢！

I haven't disabled Javascript, so I'm not sure why this the interactive debugger is broken. Thanks!

我在远程主机上运行它并通过 SSH 隧道查看它.是否有可能以这种方式禁用 Javascript?

I'm running this on a remote host and viewing this over an SSH tunnel. Is it possible that Javascript is disabled in this way?

推荐答案

解决方案是没有找到调试器提供的作为 Werkzeug 套件一部分的静态文件.只需卸载/重新安装 Flask 和 Werkzeug 即可解决此问题.感谢所有回答的人！

The solution was that none of the static files provided by the debugger as part of the Werkzeug suite were being found. Simply uninstalling/reinstalling Flask and Werkzeug fixed this issue. Thanks for everyone who answered!
