Steps to reproduce the behavior:

• Installed this on my Windows machine, where it works just fine. I have completed the reflex init and can run reflex run. However, it is extremely slow and I am recommended to use WSL.
  • I installed WSL and Ubuntu-24.04
  • Running on Python 3.12.3 in a virtual environment
  • Installed reflex and had to manually install unzip in my venv as I was getting an error that venv wasn't installed
  • I'm accessing the same reflex app from my /mnt/c/Users../Python folder/
  • Remote accessing to Ubuntu in my VS code
  • When I try reflex run, it get the above error.
  • When I try running reflex run I get the following error: Warning: The path to the Node binary could not be found. Please ensure that Node is properly installed and added to your system's PATH environment variable or try running reflex init again.

I think its advised to not run a reflex app on WSL when the project is located on the Windows file system. There are incompatibilities for that matter. Ill suggest you move the project to the WSL file system and run it there

Don't use Windows-based python inside WSL. This isn't a Reflex bug, it's an operational error. The python in Windows is unaware of any WSL libraries and vice versa. Just sudo apt install python3.12 and move your project. It will work then.
