Emotion versioning

Bug Report

Emotion version seems to be inconsistent

I’m getting import errors in npm around @emotion/, specifically some referenced classes. @emotion/core and @emotion/styled seem to be pulling incompatible versions. I don’t see a peer dependency for emotion in the docs but adding v10.0.5 of @emotion/core and @emotion/styled seems to fix the problem.

Perhaps I’m just missing the part of the docs or package.json where it’s a peer dependency?

To Reproduce

1. Delete package-lock.json and node_modules
2. npm i docz docz-theme-default
3. npm run docz:dev

The import errors I’m seeing without @emotion as a dependency:

./node_modules/docz-theme-default/dist/index.m.js
Attempted import error: 'ClassNames' is not exported from '@emotion/core'.

./node_modules/emotion-theming/dist/emotion-theming.browser.esm.js
Attempted import error: 'ThemeContext' is not exported from '@emotion/core'.

./node_modules/emotion-theming/dist/emotion-theming.browser.esm.js
Attempted import error: 'ThemeContext' is not exported from '@emotion/core'.

./node_modules/emotion-theming/dist/emotion-theming.browser.esm.js
Attempted import error: 'ThemeContext' is not exported from '@emotion/core'.

The warnings when I have emotion/core and emotion/styled as depdencies:

The documentation is compiled successfully with these warnings.

Expected behavior

Should emotion be documented as a peer dependency?

Environment

• OS: OSX 10.14.1
• Node/npm version: Node 10.13.0/npm 6.5.0
• docz / docz-theme-default: ^0.13.2

Additional context/Screenshots

Forgive me if this is off base…

In my project and docz v0.13.7, this error still prevents updating modules and yarn.lock. Clearing node_modules and yarn.lock, or installing @emotion/cache, or using npm instead of yarn doesn’t work.

[nerdmax]

Yes, @emotion/core and @emotion/styled have already installed.

However that issue is already been cleared up.

1. Install and save @emotion/cache
2. Regenerate yarn.lock: rm yarn.lock && yarn
3. Docz works well

But it is strange as actually @emotion/cache should not be necessary to install…

Agreed! Don’t know why @emotion/cache needs to be installed.
