React failing to compile postcss, yamldumper.js












1















On windows When trying to compile a freshly made react app from "create-react-app" I am receiving a compile error. Not sure where the unexpected token is coming from. The error is referring to a unexpected token in index.css from the creation of create-react-app.



index.css:



body {
margin: 0;
padding: 0;
font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Oxygen",
"Ubuntu", "Cantarell", "Fira Sans", "Droid Sans", "Helvetica Neue",
sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
}

code {
font-family: source-code-pro, Menlo, Monaco, Consolas, "Courier New",
monospace;
}


Output below from install and run:

Inside that directory, you can run several commands:

yarn start
Starts the development server.

yarn build
Bundles the app into static files for production.

yarn test
Starts the test runner.

yarn eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can't go back!

We suggest that you begin by typing:

cd derpsocial
yarn start

Happy hacking!
