there is any way for work with create-react-app behind corporate firewall by setting a proxy.

i have setted the proxy on npm and yarn, but this is what i see when try to create-react-app my-app:

I had been struggling with this for weeks. What worked for me was to include --use-npm at the end of the command and finally I got rid of the "no lockfile found" error. I sincerely hope this helps someone else struggling with the same issue.

I have had this issue as well, and I solved this with this command:

create-react-app hello-world --use-npm --cache /tmp/empty-cache

This solved my problem - See details npm config set registry "https://registry.npmjs.org"

These settings solved it for me:

npm config set proxy http://username:password@host:port
npm config set https-proxy http://username:password@host:port
