Install react and react-dom globally? When installing the cli.

[rob-bar]

When I clean install the cli I get this weird prompts on the absence of react and react-dom.
When I add them globally it works. Are they set as peer dependencies?

Is this normal? Or am I missing something...

npm install -g gatsby-cli
/usr/local/bin/gatsby -> /usr/local/lib/node_modules/gatsby-cli/lib/index.js

> [email protected] postinstall /usr/local/lib/node_modules/gatsby-cli/node_modules/core-js
> node postinstall || echo "ignore"

I ran into the same issue, also resolved with installing globally

[clarkd]

We are also seeing this issue - rolling back to 2.7.58 seems to have fixed the issue.

Without these installed globally none of the CLI commands work and you see an error saying react-dom is missing.

[ErisDS]

Also seeing this issue and had to downgrade

[jsomedon]

Having exact same error as well.

[pieh]

Opening PR with fix soon. Thanks for report!

[pieh]

Can you try installing gatsby-cli@cli-react-dom and let me know if that fixes it for you? I did reproduce the issue and seems like my fix in #18607 work for me, just want to check with you too

[KyleAMathews]

This seems like a bug in react-redux. We should also file an issue there (in addition to unblocking ourselves).

[pieh]

Yeah - react-redux imports react-dom in https://unpkg.com/browse/[email protected]/lib/utils/reactBatchedUpdates.js , but react-dom is not dep or peerDep of react-redux ( https://unpkg.com/browse/[email protected]/package.json ). I will open issue there once we hot fix it in our side

worked for me..

[Prabuela]

Same issue lie for me while installing react and react dom global it is resolved

npm install -g react
npm install -g react-dom

[jsomedon]

Works 😄

[pieh]

We are getting some failing tests on PR with fix (which is what I used for gatsby-cli@cli-react-dom version), so I'll hold off with merging and releasing it in stable channel until I investigate those

Yeah, the reasoning for this is:

• React-Redux v7 relies on importing unstable_batchedUpdates
• But, that is a renderer-specific function, so it has to come from ReactDOM or React Native, not the core React package
• We specify ReactDOM in our imports, but have a fallback file that Reat Native's bundler will pull in instead that imports from React Native
• If we specified either of those as direct dependencies, that'd screw up everybody
• If we specified either directly as peer dependencies, that'd also cause warnings for everybody
• Technically, it's also possible to use React-Redux without either, if you import from our react-redux/alternate-renderers entry point

So, since the standard use case is that folks will have ReactDOM or React Native loaded already, we don't actually specify a dependency or peer dependency on either.

It sounds like there may be some new kind of "optional peer dependencies" metadata that NPM and Yarn are starting to support, so we might end up declaring those.

[pieh]

Thanks for your response here! I lacked context around decision to not include either react-dom nor react-native and definitely we are just limited about what we can currently declare in package.json.
