Flask 找不到应用程序文件 [英] Flask can't find app file

问题描述

在 Flask 官方教程的第 2 步中，Flask 找不到我的应用程序文件，因为它在 ../venv/Scripts/ 而不是我运行命令的位置.我怎样才能告诉 Flask 在正确的地方寻找?

In Step 2 of the official Flask tutorial, Flask cannot find my app file because it's looking in ../venv/Scripts/ instead of where I run the command. How can I tell Flask to look in the right place?

(venv) C:UsersTomVCodesflaskr_tutorial>flask run
 * Serving Flask app "flaskr"
 * Forcing debug mode on
 * Restarting with stat
c:users	omvcodesflaskr_tutorialvenvscriptspython.exe: can't open file 'C:UsersTomVCodesflaskr_tutorialvenvScriptsflask': [Errno 2] No such file or directory

推荐答案

根据这个 github issue 似乎有一个错误:

There seems to a bug according to this github issue:

https://github.com/pallets/flask/issues/1829

作为一种解决方法，您可以这样做

As a workaround you can do

>python -m flask run

您还可以在本教程后面的初始化数据库(第 4 步)时使用 >python -m flask initdb.

You can also use >python -m flask initdb later in the tutorial, when initializing the database (step 4).
