I am using gatsby-plugin-styled-components: "2.0.2"and styled-components: "2.2.4".

gatsby-pluging-styled-components should have handled the SSR right? or do i still have to configure it manually? it worked fine a few months ago when i deployed the first version of my github page.

Issue can be closed. Realized its because i did not install the peer dependency for styled-components.

@jaanhio Can you explain how did you solved this? I am also getting same kind of error.

For anyone coming here from google....
make sure @material-ui/core/styles actually exports ServerStyleSheets

this lead me to realize I'm running an older material-ui/core (3.9.x)
fixed by upgrading to 4.5.1

Just had the same issue on my Next build, I ended up with the alpha release of "@material-ui/core": "^5.0.0-alpha.33" in my package.json, I swapped it over to the latest stable release "^4.11.4" and it works now.

Same thing here @sanjsanj. My next build command was working until this latest release of 5.0.0-alpha.33 but after the update it crashes.

I had the same problem and changed the import like this: import { ServerStyleSheets } from '@material-ui/styles' and now it's working fine again.
