AoT: Can't resolve ngfactory

Getting some odd errors when trying to run yarn build:production:

The build does appear to complete, but then gives me some more errors:

npm ERR! code ELIFECYCLE

I tried this with my master branch that I've been coding along with your videos, then jumped to the last branch (25 firebase) and got the same errors.

Okay, I ran rm -rf node_modules and then ran yarn and the build worked just fine.

I've been running yarn upgrade each new day I work on the project, so must be something has changed Angular that's causing the build to fail.

I'm getting this exact same error when I go and deploy this to Firebase when following along in the second video. I had this issue locally too just like you said but removing the node_modules folder and running yarn fixed it (thanks for your suggestion!). However, deploying this project as instructed in the video yields the same error with very little to work with.

[Marcidius]

I did an "rm -rf build" and did another "yarn build:production" and a redeploy via firebase deploy and it worked! Nothing more to see here.

Getting this error same as did Marcidius over a year ago. Already switched using Node version 8.11.1 but that might to too new also.

I also encountered this issue while trying to build and deploy the application for the first time. My fix was to install enhanced-resolve@3.3.0:

npm install enhanced-resolve@3.3.0

thanks @ArwinStrating that helped with the ngfactory issue, I also had an issue with @types/bluebird package when using npm run build:production

And also when trying to deploy to firebase with public: "" I got an error: Error: Must supply a public directory using "public" in each "hosting" config. changing it to public:'.' helped
