Flask 应用设置问题：PyCharm 运行时配置

如何解决Flask 应用设置问题：PyCharm 运行时配置

我不明白错误信息 Cant find {0}

我可以使用

从命令行运行flask项目

export FLASK_APP=app.py
export FLASK_ENV=development
export FLASK_DEBUG=true
python3 -m flask run

但遇到不同的问题：

  File "/Users/miranda/.local/share/virtualenvs/backend-6tST30Wu/lib/python3.8/site-packages/MysqLdb/__init__.py",line 18,in <module>
    from . import _MysqL
ImportError: dlopen(/Users/miranda/.local/share/virtualenvs/backend-6tST30Wu/lib/python3.8/site-packages/MysqLdb/_MysqL.cpython-38-darwin.so,2): Library not loaded: @rpath/libMysqLclient.21.dylib

  Reason: image not found

编辑

找到了 macOS MysqL lib 问题的答案 Library not loaded: libmysqlclient.16.dylib error when trying to run 'rails server' on OS X 10.6 with mysql2 gem

暂时放弃 pycharm。
