Create React App not installing, showing an error and aborting installation

Once you have cleaned the yarn cache by running:

yarn cache clean

then subsequent calls to:

npx create-react-app your-app

will work.

I had same issue and solved it by:

Installing latest version of node, npm and yarn.

npm install -g npm@latest
nvm install node
npm install -g yarn

nvm installs Node.js and npm manages packages.

I solved this problem by deleting .yarnrc file from C:\Users\yourUserName\
