Alternatively, you could copy your app that experiences the problem and start removing things until you’re left with the minimal reproducible demo.

(Accidentially, you might get to the root of your problem during that process.)

Push to GitHub and paste the link here.

Can you consistently reproduce this?
Could there be some network issue during install?

[erikschlegel]

Hey Dan - this happens every time. I'm also receiving the following error when trying to create a new site. Network is also working fine.

So far I can’t reproduce this with npm 3.
Will try npm 2 soon.

Can you update npm in case it’s their bug?

npm i -g npm@latest

[gaearon]

Oh okay, I can reproduce this on npm 2.

[erikschlegel]

After updating npm now getting a completely different error.

[erikschlegel]

what version of npm are you using?

[gaearon]

I don’t seem to have this problem after npm install -g npm@next.
Can you try that?

(I know it’s a lousy answer but fighting npm issues is hard.)

[erikschlegel]

I can create a site now, but still running into the same npm start issue. What I'm trying to do is integrate this package with azure, as the default way to build react based azure web-apps and use kudu for deployment. One of the things I noticed here is that the node modules created under node_modules are not defined in package.json. I guess the only workaround would be to eject and deploy the ejected package.json?

I can create a site now, but still running into the same npm start issue.

Which one? Missing lru-cache? It seems like something got messed up on publish, maybe because I was using a buggy npm version. Looking into that now.

One of the things I noticed here is that the node modules created under node_modules are not defined in package.json.

Not sure I understand the question. Can you rephrase?
npm 3 installs nested dependencies in top-level folder so it’s expected.
Just running npm install is enough, you definitely don’t need to eject or add them all to package.json.

[gaearon]

Confirming this was a result of bad publish.
I’m publishing a version right now that I think should fix this.

[erikschlegel]

Scratch the question I earlier asked. I'm able to create a new site and run npm start with using react-scripts 0.4.2. The issue seems isolated to npm version 2.

[gaearon]

Fixed with 0.4.3.
Thanks for report and quick replies.
