After Putting Node 5, Npm Err! Code Einvalidtype?

After installing Node 5, I am getting an error in the terminal everytime I run whatever with npm npm -v: 2.14.12 and here I am trying to update npm to the last version: MacBook-P

Solution 1:

I had the same issue on my linux machine. I upgraded my node from 5.0.0 to 5.1.0 and now works like a charm.

Solution 2:

same issue happend to me.

first i deleted the node_modules folder and then the package-lock.json file but the problem still persisted.

when i looked at my package.json file for some irregularities i noticed a dependency that was just an empty string - something like: "dependencies": {..., "": "^5.3.1" ,...}.

once i deleted that empty dependency, npm was running again.

hope this helps someone :)

Solution 3:

I simply deleted both the node_modules folder as well as the package-lock.json file and then rerun module installation with npm. rm -rf node_modules & then rm -rf package-lock.json and finally npm install

Solution 4:

I manually added the package name (@materia-ui/core) in the package.json and ran npm install once in the root directory and once in subdirectory (We have a mono-repo with lerna) and it worked. I have no idea how and why.

Don't forget to remove package-lock.json and node_modules
