How to start hacking mermaid?

[vallsv]

Hi,

I have tried to follow the notes to bootstrap the dev project, but got some troubles.

pnpm install

I have used pnpm 9.
This updates the lock file so in the end the file is yours, not the one from the project. It's difficult to reproduce the tests.

For other project i use to use.

pnpm install --frozen-lockfile

Unfortunately this fail with the following.

Scope: all 10 workspace projects
 ERR_PNPM_LOCKFILE_CONFIG_MISMATCH  Cannot proceed with the frozen installation. The current "patchedDependencies" configuration doesn't match the value found in the lockfile

Update your lockfile using "pnpm install --no-frozen-lockfile"

So i fall back updating the lock file.

And while trying the tests

pnpm test

<--- JS stacktrace --->

FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

Maybe related to #4886

So in the end, i don't know what to do.
Is the dev branch broken? My updated lock deps wrong? Or my my computer too small?
Do you occures the same thing? or have any idea what i could try?
