解决方案
关闭enableIvy
确实对我有用.
angularCompilerOptions
下的添加"enableIvy": false
After upgrading @angular/core
and @angular/material
using ng update
command, the ngcc
command fails with below error
command used:
ngcc --properties es2015 browser module main --first-only --create-ivy-entry-points
Error:
> Compiling @angular/cdk/stepper : es2015 as esm2015
> Compiling @angular/cdk/drag-drop : es2015 as esm2015
> Error: Error on worker #3: Error: Tried to overwrite node_modules/@angular/cdk/stepper/step-header.d.ts.__ivy_ngcc_bak with an ngcc back up file, which is disallowed.

解决方案
Turning enableIvy
off, did work for me.
from tsconfig
file, under angularCompilerOptions
add "enableIvy": false
