Error: ENOENT: no such file or directory, open './.cache/devnet-temp'

While running yarn setup-dev

I'm having an issue getting this setup on Ubuntu. It looks like a file is missing. I tried creating an empty file and removing the check for the file but it creates errors for NEXT_PUBLIC_CANDY_MACHINE_CONFIG

$ node ./devtools/dev/setup-envs-dev.js
internal/fs/utils.js:314
    throw err;
    ^

Error: ENOENT: no such file or directory, open './.cache/devnet-temp'

This is what fixed the issue for me: In setup-envs-dev.js, at line 42, it has:

const metaplexTempFile = fs.readFileSync('./.cache/devnet-temp');

which is missing the .json extension. Replace with:

const metaplexTempFile = fs.readFileSync('./.cache/devnet-temp.json');
