I even tried the npm audit fix command but, It doesn't help me either.

As far as I know they are harmless. But if you are really absolutely annoyed with them, losing sleep, or making you showers unclean 😆 you can try theese:
Install typescript and eslint:
npm install typescript
npm install eslint
This is for appeasing these warnings

npm force install I suggest you to not do this often if you don't have any problem. But this might be a good case.
npm install -f
This command is to placate these warnings:
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules/jest-haste-map/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

Again they are harmless and you can try to live with them. Or you can try the commands above to have some small relief in life 😁

I understand this is a few months old but I thought I'd contribute my solution. It turned out for me that a particular version of typescript was looking for an older version of eslint. I used the npm-update-all global tool to bring all my packages up to date. The typescript updated to 3.6.4 and all the peer warnings went away. Of course you want to use a drastic measure like updating everything with discretion.
