Debug in Pycharm
Hi Team,
I would like to run pynecone from a Pycharm Run Configuration to be able to set breakpoints in the code.
Did anyone get this working? I tried adding the following lines to my pynecone sample app:
if __name__ == '__main__':
from pynecone.pc import main
main(["run"])
However, running that fails with
──────────────────────────── Starting Pynecone App ─────────────────────────────
Traceback (most recent call last):

Hi, I do it this way and it works for me, I hope it can be useful for others as well.
Clone this repository, don't use pip version
git clone https://github.com/pynecone-io/pynecone
Navigate to the folder cd pynecone just cloned
Setup a virtual env (PyCharm will do it for you)
Run pip install .
Now create a new Python configuration from PyCharm
Now set Script path with pc.py path
Parameters: run
Working directory: folder of your current pynecone project.
See this example for quick overview
If somebody debugs on vscode, the launch.json looks like below:
the cwd is the working directory.
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

"version": "0.2.0",
"configurations": [
{
"name": "pc",
"type": "python",
"request": "launch",
"program": "${workspaceFolder}/pynecone/pc.py",
"console": "integratedTerminal",
"justMyCode": true,
"args": ["run"],
"cwd": "${workspaceFolder}/examples/hello_world"
}
]
}
Even better is using the module...this should be able to be translated to either pycharm or vscode or whatever debugger you want to utilize.

"name": "pynecone gui",
"type": "python",
"request": "launch",
"module": "pynecone.pc",
"justMyCode": true,
"args": [
"run"
],
"cwd": "${workspaceFolder}/gui"
}
Now set Script path with
pc.pypath Parameters: run Working directory: folder of your current pynecone project. See this example for quick overview
For me, this allowed running, but not debugging and hitting breakpoints. (In Pycharm)
Hi everyone,
Having a working debugging environment in PyCharm would indeed improve the developer experience. Has anyone found a workaround with the new Reflex naming? I can get PyCharm to stop at the breakpoints on initial rendering, but not with subsequent reloads.
