What is the (ERR! code ENOLOCAL npm ERR!) Could not install because of an error?

Question

I am going to update npm latest version, but it's showing this error message:

G:\>npm i -g npm ERR! code ENOLOCAL npm ERR! Could not install from "" as it does not contain a package.json file.  npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\hemanth\AppData\Roaming\npm-cache\_logs\2018-01-08T03_34_29_774Z-debug.log G:\> 

Answer 1

This is an issue in node which is caused by white space in your windows username (possibly between the first-name and last-name in windows).

run the following command after replacing firstname with your windows user firstname in command prompt with administrator access

npm config set cache "C:\Users\Firstname~1\AppData\Roaming\npm-cache" --global 

Answer 2

This worked for me:

npm cache verify 

Then I re-ran:

npm install -g create-react-app 

And it installed like as expected: Issue resolved
