gatsby-plugin-emotion: emotion 11

[k-m-a-c]

Description

The development version of the tutorial-part-four project in the official Gatsby tutorial series fails to build, erroring out because it relies upon gatsby-plugin-emotion and @emotion/core, the latter of which has just released a major version update with breaking changes to the package’s naming.

Specifically, there are 2 issues that cause the build failure:

1. gatsby-plugin-emotion lists @emotion/core in its peerDependencies with an optimistic version operator (i.e. ^10.0.5), which causes the latest version of the package to be relied upon at build time.

2. The code samples in the documentation include imports that reference @emotion/core instead of @emotion/react.

Steps to reproduce

Run through the steps in tutorial-part-four from scratch.

Expected result

The tutorial project’s development build is created without error.

Actual result

The development build fails out with the following error:

I am facing the same problem right now.

[LekoArts]

You are incorrect with your first assumption, the peerDependency is still requiring version 10. So if you install that instead of 11 it'll all work.

[dhonysilva]

I handled this issue by specifying the version 10.0.5:

npm install gatsby-plugin-emotion @emotion-core@^10.0.5

I handled this issue by specifying the version 10.0.5:

npm install gatsby-plugin-emotion @emotion-core@^10.0.5

I'm facing the same issue as above. I tried reinstalling emotion in my project root directory using version 10.0.5, as @dhonysilva mentioned , but I keep getting;

npm ERR! code EINVALIDPACKAGENAME
npm ERR! Invalid package name "@emotion-core": name can only contain URL-friendly characters

That was it, thanks!

[tumetus]

Reinstalling with @emotion/core@^10.0.5 solved this for me too 👍

[cleaver]

I changed to @emotion/core to @emotion/react and it solved the problem. The module was renamed recently.

Edit: #27981 goes into more detail.

[hamdannurachid]

npm install gatsby-plugin-emotion @emotion/core@^10.0.5 solved for me thanks

[martin-sweeny]

If you want to use the upcoming version of gatsby-plugin-emotion, instead of using the deprecated @emotion/core:

yarn upgrade gatsby-plugin-emotion@5.1.0-next.0

At least until 5.1 is released on npm

[zerogami-cami01]

私も、WebpackError: The @emotion/core package has been renamed to @emotion/react. Please import it like this import { jsx } from '@emotion/react'.というエラーが出たので、npm install gatsby-plugin-emotion @emotion/core@^10.0.5を実行したところ解決できました！ありがとう！

[svirins-zz]

yarn upgrade gatsby-plugin-emotion@5.1.0-next.0

Wow! Thank you, Martin! Switching to the upcoming version completely solved the issue.

[bildungsroman]

I'm using "gatsby-plugin-emotion": "^5.4.0" and still hit this issue. While adding @emotion/core@^10.1.1 fixes it for now, I'd rather not have to install that package when I'm already using @emotion/react. Is there a solution on the horizon?

[Samar2170]

i tried the fix npm install gatsby-plugin-emotion @emotion/core@^10.0.5 , but the error changed to Can't resolve '@emotion/styled' in '/home/samar/Desktop/Gatsby/template/node_mod
