Cannot setup dev environment

This issue has been tracked since 2023-01-25.

Hi there,

I just wanted to contribute to tweakpane, I cannot get the dev environment to work.

I run npm install and npm complains, that it cannot find a version of tweakpane/core. I selected the most recent one.

After that I run npm run setup and setup:core fails with the following error message:

71 verbose stack TypeError: Cannot set properties of null (setting 'dev')

I tried it with Node 16 and 18 (NPM 8). Which version are you using?

Thank you for using Tweakpane! Here is the result of my development environment:

% node -v                                                                                                           [main]

% npm -v                                                                                                            [main]

Ok, apparently some kind of issue with NPM. It works, when I use npx to specify a npm version and then run the commands in each package manually:

cd packages/core
npx [email protected] install && npx [email protected] run build 
cd ../tweakpane
npx [email protected] install && npx [email protected] run build

I found an issue that may be related to this problem. It seems to occur with npm workspaces, but I cannot find a solution...:

Anyway I'm glad it went well.
