informed: Module not found: Can't resolve '@babel/runtime/core-js/json/stringify'

I’m a newbie. I’ve installed informed as per the docs, but am getting the following error when I try to yarn start.

Failed to compile.

./node_modules/informed/dist/index.js
Module not found: Can't resolve '@babel/runtime/core-js/json/stringify' in '/home/chris/code/elixir/blog/blog/node_modules/informed/dist'

What am I doing wrong?

PS I have done npm install --save babel-runtime in my project, although I don’t see why this is necessary.

Looks like in @babel/runtime@7.0.0-beta.56 they split the runtime into 2 packages. This package is built with a pre-56 version but will allow a post-55 version to be installed.

Adding the following to your package.json should fix this

"@babel/runtime": "<=7.0.0-beta.55",

v7.0.0-beta.56

Adding "@babel/runtime": "<=7.0.0-beta.55", to you devDependencies in package.json did work as per @samlecuyer . Remember to run ‘npm i’ thereafter.

I ran into this issue just now too but did manage to get it working.

You will need to ensure you have the right versions of both @babel/runtime and @babel/plugin-transform-runtime… that is if you are using a later version of babel, all versions need to match all other babel versions (at least that’s what’s been my issue. Then add the following to your .babelrcjs:

"plugins": [
    // ...other plugins
    "@babel/plugin-transform-runtime"
  ],

But yeah, not sure why the npm version needs this, I’d prefer the npm distribution to be independently deployable without needing babel installs. There may be a good reason for this that I just don’t know about - total newbie to this repo.
