Answer 2

I had similar issue while tried creating new react app with create-react-app, but related to some random JSON reading issues while installations like.. >= 5.0 || 4.0 ..

But the fix below solves multiple and similar issues.

First of all, make sure you have required or latest version of node installed.

npm install npm@latest -g

Before using create-react-app make sure you clean npm cache using npm cache clean --force

Now, is should be fine to create new react app with npx create-react-app tl-app or npx create-react-app . if you want to create current directory as project root.

Answer 3

What I did, is going to

C:\Users\mycomputerName\AppData\Roaming\npm\

I changed the name of this file

create-react-app.ps1

to

create-react-appOld.ps1

or you can delete it, then it worked fine

Answer 4

If npm cache clean --force doesnt work please run the following

npm init react-app project-name

Replace 'project-name' with the name of the folder you'd want. Goodluck

Answer 5

After no luck with updating my npm version and doing npm cache clean --force I ended up just doing a fresh install of node which fixed the issue for me.

Answer 6

HAD the same problem. Running Node with cra. installed cra -g for starters.

npm install -g create-react-app

then downgraded react-scripts to version 2.1.8

npm install react-scripts@2.1.8

created a .env file in root directory and added this to it.

DB_HOST=localhost
DB_USER=root
DB_PASS=s1mpl3

SKIP_PREFLIGHT_CHECK=true

Then you do the typical delete node_modules folder and the package-lock.json file.(NOT PACKAGE.JSON!!!)

then:

npm install
npm start

This worked for me. Sorry I'm not more informative on why this worked for me. I'm still trying to understand why it didn't work in the first place.
