问题 I've tried reinstalling node and removing appdata/roaming/npm and npm-cache. I've created several apps before so i'm not sure what's going on. Any help is appreciated. 回答1: this issue is fixed with 2.2.2 version of is-promise package. If you still experience problems creating new CRA, consider npm install -g --force create-react-app If even then bug is still present, please comment your issue to this github issue 回答2: I would: Restart the machine. Ensure you log out of your session if needed
