I found a similar unsolved discussion that might be relevant to your issue: Error on docker-api-1 [1].
The ImportError for the 'gevent' and 'flask_cors' modules when running the Flask application in PyCharm's Debug Configurations is likely due to the modules not being installed in your Python environment.
To resolve these issues, you need to install the missing modules. You can do this by running the following commands in your terminal:
pip install gevent
pip install flask_corsAdditionally, ensure that your PyCharm Debug Configuration is correctly set up to use the appropriate Python interpreter and environment variables. Here is an example configuration that you can use as a reference:
{
"version": "0.2.0",
"configurations": [
{
"name": "Python: Flask",
"type": "debugpy",
"request": "launch",
"python": "${workspaceFolder}/.venv/bin/python",
"cwd": "${workspaceFolder}",
"envFile": ".env",
"module": "flask",
"justMyCode": true,
"jinja": true,
"env": {
"FLASK_APP": "app.py",
"GEVENT_SUPPORT": "True"
},
"args": [
"run",
"--host=0.0.0.0",
"--port=5001"
]
},
{
"name": "Python: Celery",
"type": "debugpy",
"request": "launch",
"python": "${workspaceFolder}/.venv/bin/python",
"cwd": "${workspaceFolder}",
"module": "celery",
"justMyCode": true,
"envFile": ".env",
"console": "integratedTerminal",
"env": {
"FLASK_APP": "app.py",
"FLASK_DEBUG": "1",
"GEVENT_SUPPORT": "True"
},
"args": [
"-A",
"app.celery",
"worker",
"-P",
"gevent",
"-c",
"1",
"--loglevel",
"info",
"-Q",
"dataset,generation,mail,ops_trace,app_deletion"
]
},
]
}These commands and configurations should help resolve the ImportError when you run your Flask application in PyCharm's Debug Configurations [2][3].

When I started locally with source code, using Pycharm's Debug Configurations, the following error occurred
this is problem：

but when i change environment variables ,this is new problem: FLASK_APP = app.py FLASK_ENV = development FLASK_DEBUG = 1 In folder /Users/qixiaodong/project/dify/api /Users/qixiaodong/.pyenv/versions/3.10.0/bin/python3 -X pycache_prefix=/Users/qixiaodong/Library/Caches/JetBrains/PyCharm2024.2/cpython-cache /Applications/PyCharm.app/Contents/plugins/python-ce/helpers/pydev/pydevd.py --module --multiprocess --qt-support=auto --client 127.0.0.1 --port 61992 --file flask run --host 0.0.0.0 --port=5001 Connected to pydev debugger (build 242.21829.153)
