Package install failed, see above.

Tried clearing cache, and running the command again. doesn’t work.
Tried the following steps, but didn’t work:

deleting npm , npm-cache folders from C:\Users\Username\AppData\Roaming
2)uninstall node js
4)install again
run command “npm install -g @angular/cli”
run command “ng new firstproj” gives the same error. “cb() never called”.
Is there any solution for this?

[crash] npm ERR! cb() never called!

I’m pretty sure this has to do with that awful heisenbug we’ve been hitting recently where the cli just… exits (which is very strange).

Can you reproduce this reliably? Does it happen if you use npm@5.7.0?

(Komkumar) #3

this happens every time i try creating new project using “ng new”. Haven’t tried with npm 5.7.0

I have attached the log file

If I may chip in my $0.02.

I have been able to reliably reproduce this behaviour with every npm release from 5.7.0 (inclusive) onward. Latest attempt being 6.2.0 on node@10.6.0.

To reproduce I can take almost any sufficiently large project and then

rm -rf node_modules package-lock.json
npm install

… in order to get the dreaded cb() never called! message.

Where “sufficiently large” means that it seems to need a “certain” number of dependencies. That is, in hoping to perhaps identify a certain dependency as the culprit I have been doing the above repeatedly, starting from zero, adding one dependency at a time until the problem started occurring.

Turn’s out I couldn’t nail it down to a single dependency this way; only the number of dependencies seems to matter, and more disturbingly, when I just hit that “critical mass”, it didn’t even happen all the time. Only a further increase of the number dependencies did turn the problem into becoming a “reliable” occurrence.

(Kat Marchán) #6

Can you put together a package.json/package-lock.json combo that I can reliably reproduce this with?

(David Bouman) #7

Sure! Though you won’t actually need the package-lock.json since the steps to reproduce delete it just prior to doing the “npm install”.

That said, I just found that only an “rm -rf node_modules” is also sufficient to reproduce the behaviour.

(And now I’m told I lack the privilege to upload more than one attachment; So, I guess I can upload the package-lock.json in a second reply if you really need it but I’m sure the package.json alone will do the trick).

package.json` (1.4 KB)

If it helps, this happens on macOS Sierra 10.12.6.

(Komkumar) #8

Uninstalling and re-installing node (repeating the process multiple number of times) , restarting the system after uninstall, now I am finally able to create a project using “ng new”. I am still not sure about the root cause for this error

Please continue future discussion in [crash] npm ERR! cb() never called!, which is a proper bug report, and this is definitely a bug.
