I have upgraded from Angular 8 to 9 and have enabled Ivy following all the steps here. When I run npm install
a handful of my packages throw the error:
Tried to overwrite <package_path>.__ivy_ngcc_bak with an ngcc back up file, which is disallowed
.
What does this mean and why is it happening? I'm having a hard time finding any info on it. I've installed the latest version for all of these packages throwing this error and I still get the error when I run npm install
. Thanks!
