Errors when running: npm run dev (step 4 in the readme)

[houghtonweihu]

I was able to run: python -m ochat.serving.openai_api_server --model openchat/openchat-3.5-0106
I finished steps 1, 2, 3 in readme and when I tried step 4: npm run dev, I got the following:

[email protected] dev
next dev

openchat-ui/node_modules/next/dist/lib/picocolors.js:134
const { env, stdout } = ((_globalThis = globalThis) == null ? void 0 : _globalThis.process) ?? {};

upgrade node.js to the latest fixes it for me.
