num2fraction | Converting Number to Fraction with Node.js | Runtime Evironment library

I have created one angular library using angular 8 and CLI 8. I am trying to build the library, but I am getting the error.

I'm trying to build my ionic app with --prod flag but I'm getting issues doing it.

After upgrading to ionic 3.18, some time ago, there was some problems and I couldn't run my app anymore. I forgot what were the problems but I solved them somehow with some tweakings in my package.json, if I remember well, and I was able to run the app.
But since that, I can't get it to build with --prod flag (but it works fine without).

Today I was looking into this problem and tried deleting my node_modules and rebuilding it following this advice. It solved the specific issue there was, but I still cannot build the app.

Here is the result of rebuilding node_modules folder running npm i: (I removed a few lines without any error in the middle, because it was too long to post otherwise.)

I'm trying to go on my angular 2 webapp but I get this error on each page :

I haven't changed anything in the app, and it works on computers of people of my team.

Is it caused by these warnings when npm install ?
