Vite not found

If you build has been failing at the Install Apps stage with vite: not found in the build output, such as this:

Then it means that the vite build dependency wasn't installed when your app was being installed.

Why does this happen?

This can happen if your project has two package.json files such as this (repository):

And if the outer package.json does not have a postinstall script that installs packages mentioned in the inner package.json.

Ensure that your outer package.json has a postinstall script with a line similar to this:

cd frontend && yarn install

Here frontend is the folder with the inner package.json.

You can use frappe/gameplan as a reference point.
