错误：模块未自行注册

Question

I have the exact same error which says

at bindings (/node_modules/pg-native/node_modules/libpq/node_modules/bindings/bindings.js:76:44)  

This might seem similar to:
Error: Module did not self-register.
but the difference being, I am using docker to build images, so it will not be possible for me to go back and remove node_modules and perform npm install again for every container.
Is there a more elegant solution?

Answer 1

One of the advantages of Docker is that it should be easy to upgrade your images and replace your containers. If you have a bunch of Node apps which all start from the same image:

FROM node

Then you just need to rebuild your images and they will use the latest version of the Node base image (which currently has NPM 3.10.3 ). In a non-production environment, just stop your container and run a new one from the new image. In production, look at rolling upgrades in swarm mode .

Ideally you should be working towards an automated workflow where you commit a change, that builds a new image and replaces your running container. You shouldn't need to do any maintenance on running containers - they are meant to be disposable.

Answer 2

I was getting this error when I ran docker-compose. Also, in my docker-compose I was mounting the current folder. To fix this issue I rebuilt my node modules with npm rebuild .
