nx.dev creating first app failure with cannot find module

Question

In trying out nx.dev, I ran this command

npx nx generate @nrwl/node:app ghApi

and received this error

Unable to resolve @nrwl/node:app.
Cannot find module '@nrwl/node/package.json'
Require stack:
- /Users/dean/workspace/gazehealth/nxdev-workspace/node_modules/nx/src/utils/nx-plugin.js

- /Users/dean/workspace/gazehealth/nxdev-workspace/node_modules/nx/bin/nx.js

I simply followed instructions from https://nx.dev/getting-started/nx-and-typescript any ideas?

I had a similar issue.

Try: nx report

You will see something like this:

 >  NX   Report complete - copy this into the issue template

   Node : 16.15.0
   OS   : darwin x64
   npm  : 8.5.5
   
   nx : 14.2.2

   @nrwl/cypress : 14.2.2

   @nrwl/devkit : 14.2.2

   @nrwl/storybook : 14.2.2
   @nrwl/web : Not Found
   @nrwl/workspace : 14.2.2
   typescript : 4.7.3

In my case @nrwl/node was "not found"

So I just Installed it with: npm i @nrwl/node

And after that, the nx g @nrwl/node:app MyAppName worked.

I hope this can help!

Answer 2

These issues are sometimes related to node versions. Check which node version you used to install the dependencies.

In my case, I used node 14 instead of node 16

After the node upgrade and reinstalling of all the node packages, the application did work fine.
