Need to continually re-install node modules after every angular library build

Question

I found it really hard to phrase this question. I hope it makes sense. I have searched here and more generally to try to find a reference to this behaviour but haven't found anything.

I have an angular library project which has been working perfectly for several months.

Wanting to add a new (slightly complex) new feature to the library I got tired of copying the built library to my main project after each test.

After some research, I discovered npm link which I hadn't used before. This worked brilliantly for about a week. After each change in the library project I rebuilt the library and the changes were immediately available in my main project.

Then just yesterday something really weird started happening. I went to build the library project and got pages or errors. (See below)

Reinstalling all the npm packages fixed the problem but when I went to used my main project, all the errors reappeared there.

Then I made some changes to the library project and went to rebuild and all the errors were back again.

Any ideas on what is happening here??

2020-06-30 Edit

As per one of my comments below, this was OK for a few days but I had to re-install yesterday and again this morning.
