Is your WSL environment based on Debian? I’ve noticed some strange behaviours with npm in Debian Buster that I’ve not been able to reproduce with the official nodejs binaries and updated versions of npm (node is v10.15.2 and npm 5.8.0 in Debian Buster). Among those were hanging npm ci commands in GitLab runners with docker and the yarn error you’ve got when I executed vue create foo.

I think this error is related to this create-react-app issue which is caused by the way the browser is launched in WSL (using cmd.exe which is not in the PATH). The root problem may be in the opn aka open npm package.

A workaround is to add /mnt/c/Windows/System32 to your path before running the command.

e.g.:

PATH="$PATH:/mnt/c/Windows/System32"   /node_modules/.bin/vue-cli-service serve

or

export PATH="$PATH:/mnt/c/Windows/System32"
/node_modules/.bin/vue-cli-service serve

The former command will not alter your current shell while the latter will, so choose the one that suits your needs best.

Disable browser auto-opening by edit vue.config.js,

module.exports = {
  //...
  devServer: {
    open: false
  }
};
