The signature of the first argument is a string, so that's expected. What did you pass through to it?

im not sure，probably not this fun error;

this error was trow in styled-components which use stylis.js

[thysultan]

Have you tried to install the latest styled-components? Maybe it's fixed upstream, otherwise i'd suggest opening an issue there.

Yes, above issues is in styled-components with version 2.1.1 (latest) ,and work well in version 2.1.0

thanks for replied! i guess above issues will be styled-components self

I feel like the issue could be a dependency cache issue with npm since the screenshot you posted doesn't look like the latest version of stylis.

Can you confirm that the dependency stylis is at version 3.2.8?

I say this because there was a release of styled-components that relies on a new feature of stylis, specifically this styled-components/styled-components#962. So if the stylis dependency did not update locally then that might be the problem.

I meant node_modules/stylis/package.json If it's < 3.2.0 either try to npm install styled-components again/ npm install stylis to update it specifically.

Since the error was from stringifyRules.js#L5, it was probably because the dependency did not update, can you still reproduce the error after updating?

[ghost]

yes the error still reproduce after updating

I think it's exactly as philpl said, beyond that, a repo with the problem would help. But i don't think the problem is from this end.
