heroku python入门教程EISDIR错误

Question

按照Heroku的Python入门教程，我遇到了一个错误

当我运行:

heroku local web

我得到错误:

internal/fs/utils.js:269
throw err;
^

}

Answer 1

这个错误是由于我使用。env作为我的python venv文件夹

python3.9 -m venv .env --prompt='heroku-getting-started'

看起来heroku的python入门期望.env是这个

$ cat .env
TIMES=2

我最终将python venv移动到.venv，错误消失了
