Flask debugger configuration fails (Window) with "could not import" message #1634
Description
2018.4.0 release.
Windows 10
Also reported as microsoft/vscode#48972.
Repro steps:
- Create a "hello.py" with code like the following:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_flask():
return '<html><body>Hello, <strong>Flask</strong>!</body></html>'
if __name__ == '__main__':
app.run('localhost', 5555)- Run the app under the Python: Current File configuration. Result: success.
- Run the app under the Python: Flask configuration. Result:
D:\py\Flask>cd d:\py\Flask && cmd /C "set "FLASK_APP=D:\py\Flask/app.py" && set "PYTHONIOENCODING=UTF-8" && set "PYTHONUNBUFFERED=1" && d:\py\Flask\env\Scripts\python.exe

* Serving Flask app "D:\py\Flask/app.py"
* Environment: production
WARNING: Do not use the development server in a production environment.
Use a production WSGI server instead.
* Debug mode: off
Usage: python -m flask run [OPTIONS]
Error: Could not import "D".
Seems like a problem parsing the path.
