create-react-app: Create react app dependency error

I just tried with npm@5 and I saw the error noise (although eventually the installation finished successfully for me). In the meantime I recommend downgrading: npm i -g npm@4.

I’m fairly sure it is this npm bug: https://github.com/npm/npm/issues/16810. Unfortunately there’s nothing we can do until it’s fixed.

---

If you’re having this issue please roll back npm to a version without this bug:
npm install -g npm@4

---

If you still have a problem after downgrading npm please file a new issue with screenshots and details about your system.

Full error message (so that Google picks it up):

Try:

• Removing package-lock.json if you have one
• Removing yarn.lock if you have one
• Downgrading npm to 3.x if it’s newer
• Run npm install
• Then run npm start

Does this help anyone?

I have same problem.

• node 8.1.2
• npm 5.0.3
• create-react-app 1.3.1

I try to downgrade npm to npm 4 latest. I have no problem.
