Trying to deploy my React app with gh-pages but got this error message : The "file" argument must be of type string. Received type undefined
Seems like a bug in gh-pages 2.1.
I solved mine by downgrading gh-pages to version 2.0:
yarn add gh-pages@2.0 -D` // ornpm install -D gh-pages@2.0
Update: Fixed in gh-pages@2.1.1. You can now update your gh-pages package to latest version to fix this.
npm i gh-pages@latestIf you don't wish to downgrade to version 2.0.1, the workaround is to instead of using "deploy": "gh-pages -d build" as your deploy script, use:
"deploy": "gh-pages -d build --git git"This somehow fixes the problem.
You can find the GitHub issue about this bug here: tschaub/gh-pages#308
Whenever you start your program, you use npm start. This can be used for Deploy too. Instead of doing npm run deploy, the command should be npm deploy.
