[RESOLVED] Meteor 1.6 incompatible with Angular CLI + shared `node_modules`?


#1

I have been using Meteor 1.3.x-1.5.x for the server in an Angular-Meteor project with a web client built via Angular CLI. Up until Meteor 1.6, I have been able to use a single node_modules directory shared via a symlink to reduce the size of and easily keep in sync the many shared dependencies between the client and server, following the example of the Angular-Meteor starter applications.

However, from the new package-lock.json file appearing in the root of the server directory, Meteor 1.6 appears to install its own dependencies in node_modules, including many @angular/* dependencies, which result in me get the following errors due to the multiple, conflicting package installations. Any recommendations?

This likely means you have several @ngtools/webpack packages installed. You can check this with `npm ls @ngtools/webpack`, and then remove the extra copies.

Migrating to Meteor 1.6
#2

I was able to resolve this by:

  • updating to node@8.8.1 globally to match the version bundled with Meteor 1.6
  • updating to Meteor 1.6
  • adding symlinks to the root package.json & package-lock.json inside the Meteor directory
  • deleting the node_modules folder and performing an npm install on the root package.json
  • avoiding any calls to meteor npm install (which I had been doing in a postinstall npm script to build the bcrypt binary)
