Unable to resolve dependency tree when using npm install error

Question

So when I cloned a project and ran npm install in my bash terminal, it gave me this "unable to resolve dependency tree" error. I checked to see if I wasn't in any subfolder and I deleted my node_modules and package-lock.json as well. I have node version 12.18.3 and npm version 7.12.1. I'm certain I have updated both of them. I even ran the command npm i --force and npm i -legacy-peer-deps and both didn't work. Terminal error

Answer 1

Try deleting node_module, package-lock.json, and then run the following:

1. npm cache verify
2. npm install
3. npm start
