npx create-react-app myapp error "\AppData\Roaming\npm-cache\_npx\19748" does not contain a package.json file in appdata folder

OS: Windows
for creating react app using npx i've write the following command:

npx create-react-app myapp

it shows this error:

npm ERR! Could not install from "myusername\AppData\Roaming\npm-cache\_npx\19748" as it does not contain a package.json file.

How can i fix it?

Solution

  • this error occurs usually when name of the PC contain a space like

    mycomputer name

    you should fix this by redefine your npm cache root There is a simple workaround to fix this problem. 8.3 DOS path format should be used. Open command prompt in administration mode then cd to C:\Users and run this command :

    C:\Users>dir /x

    and find the short path for your desired directory i.e. username let us say it is MYCOMP~1 (it's not always MYCOMP~1 ) try:

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

    be careful for space character in the pc name you should use the one you got from command prompt instead and now use:

    npx create-react-app myapp

    happy coding!!!
