running example fails on windows (RuntimeError: Unable to open config file C:\Users\user\.ocpvscode)

[edrihan]

There are two cases I tried. The first was running:

python -m pip install --upgrade pip
python -m pip install git+https://github.com/gumyr/build123d

This seemed to work, but then I had to run pip install ocp_vscode, and it seemed to work, but then I get the state that we are in here. What I mean is that the only difference between installing latest and stable was the missing ocp_vscode. But once you have it installed, the two cases are the same, in that the next stuff happens.

I did pip install build123d
Then I copy pasted the canada flag example into a file and ran it. This is the output:

Lock file C:\Users\user\.ocpvscode.lock already exists
Lock file C:\Users\user\.ocpvscode.lock is stale

The above exception was the direct cause of the following exception:

This seems like a bug with ocp_vscode not creating a config file. But being that this project uses it.. I can't run the example based on the instructions in the README.

ocp_vscode is a separate project from build123d - you could raise an issue here: https://github.com/bernhard-42/vscode-ocp-cad-viewer or as for assistance in the CadQuery/build123d Discord.

A couple things to try though:

1. Open a Folder in vscode (File->Open Folder)
2. Close vscode entirely and re-open it

Assuming you are running ocp_vscode in standalone mode, this is a known issue and documented on the appropriate repo bernhard-42/vscode-ocp-cad-viewer#121
