npm install --timing not saving full debug log

Question

I'm running npm install --timing, and when it completes it will output something like:

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/mesher/.npm/_logs/2022-05-14T18_33_08_821Z-debug.log

Problem is, that debug log does not contain a complete log.

Looking at that file, I see that it only has a little over 15k lines, and the first line in the file starts at over line 110k:

110055 silly postinstall [email protected]
110056 info lifecycle [email protected]~postinstall: [email protected]
110057 silly postinstall [email protected]
110058 info lifecycle [email protected]~postinstall: [email protected]
...

Is there a way to get an actual complete npm install log?

Thanks

If you add --loglevel verbose to your command all of your logs will be printed to STDERR, as well being saved to npm-debug.log in your current directory like --timing does. However, this should provide more information around the error:

npm install --loglevel verbose

This should get you a more complete log file. You can find more about how npm handles logging in the docs.
