Description

Recently I updated my Angular project dependency versions and I get this error when trying to build a library:

ERROR: Unknown version 67 of android
An unhandled exception occurred: Unknown version 67 of android
See "C:\Users\doteteix\AppData\Local\Temp\ng-5ErChV\angular-errors.log" for further details.

I can get more detail from this angular-errors.log. This is the extra info:

How To Reproduce

I try to build my lirary executing:

ng build core

Expected Behaviour

The library is built as expected and as usual before I updated versions.

@mrtijn I was able to fix it by taking these steps:

1.Deleting the entire node_modules directory 2.Deleting package-lock.json from the root directory 3. Making sure the latest @angular-devkit projects were referenced in package.json:

"@angular-devkit/build-angular": "^0.801.3", "@angular-devkit/build-ng-packagr": "^0.801.3",

Running npm install

That fixes it. Have no idea why.

I have tried @andrewryan1906 solution. I deleted my node_modules and package-lock.json file, re-installed with "@angular-devkit/build-angular": "^0.801.3" and "@angular-devkit/build-ng-packagr": "^0.801.3"

I am still getting:

BUILD ERROR Unknown version 67 of android An unhandled exception occurred: Unknown version 67 of android

SOLUTION UPDATE:

I had to explicitly install the working version of “caniuse-lite” to version “1.0.30000997”
