node-pre-gyp: Error: Completion callback never invoked

face the same issue

npm install -g node-pre-gyp …(this will install v0.9.0) npm update node-pre-gyp …(this will update it to 0.10.0)

or alternatively npm install -g node-pre-gyp@0.10.0

Hello, I had the same problem, I disabled my antivirus (kaspersky) and it ran like a charm. Hope it can help.

how to solve this？？？？

Try with yarn instead of npm. it works for me.

For me, it was a network issue. switched to mobile hotspot and it worked

This is really annoying.

I ran into this issue today in my Mac Pro with node v8.

Is there a workaround to make it work?

Update

I just made it work after I switched my computer from the Wifi(China Telecom) to my Android Phone Hotspot(China Mobile).

Before

Conclusion

I believe it’s a network issue on my case. We should have more clear error message for this kind of situation.

@D4you208 I had this issue when using firebase cloud functions… (it was used by firebase-admin i think)… So i solved it by “npm install firebase-admin --force”… But this solution could work only for cloud functions, because it’s executed on the server and i think there isn’t such problem… So all i need to install it locally to pass lint check before deploy… (i think it will not work locally)

has anyone fixed this issue yet?? Mine always works for a short period of time then all of a sudden this issue shows up… After i gave up on windows i dualbooted with an ubuntu and installed it there then it fixed my problem… Then it worked for a short period and then the problem came back… I immediately installed it on a third OS , this time on a mac but the same issue showed up from the beginning… I have a feeling Node is simply broken… No matter how many times i switched node version with nvm and reinstalled node and everything it never installed firebase and angularfire2 …

In my case , deleting the package lock and re generating it solved the problem

was having the same problem, uninstalled Node v12 and installed Node version 10.19 and it worked for me https://nodejs.org/dist/latest-v10.x/

Thanks for the detailed report @zixia

I believe it’s a network issue on my case. We should have more clear error message for this kind of situation.

If you upgrade (or ask the grpc developers to upgrade) node-pre-gyp to v0.10.2 I think the error message will improve since v0.10.2 includes https://github.com/mapbox/node-pre-gyp/pull/377.

A potential root cause would be network failure or potentially (if you are behind a proxy with one network) #400
