I ran into a bit of an issue with my NS NG2 app. Whenever I try to run the command tns livesync android --watch, or any other command to build, I receive a very long list of errors. Below is a small snippet of this error.

This is just a very small sample of the errors I am receiving.
This happened when I went to work on my mac and then transferred to my PC. I pulled the small code changes I made (have already tried to reverse these) and tried to build. That is when I was met with this error list. I am going to list a few files below that may help in finding the answer.

To solve this issue, I went through every single line of my package.json and looked up each module. Checked for their recent updates and set it to install a version last updated about 20 days ago. For each one. After deleting my node modules and doing npm install 4 times, it worked.
