Can you please provide reproducible demo? Thanks

Probably a bug in the prop-types transform.

[multum]

@stereobooster I'm not sure that I can reproduce the error ... This happens only when you run the command npm run build

[multum]

@gaearon The error appears only when determining the prop-type as follows
[SOME_CONSTANT] : PropTypes.arrayOf(...) or PropTypes.oneOfType(...).

Determining a key without a constant and [] leads to a successful build
someKey : PropTypes.arrayOf(...) or PropTypes.oneOfType(...)

@av-dev If you could provide a full reproducing example on https://github.com/oliviertassinari/babel-plugin-transform-react-remove-prop-types side, it would be awesome :).

@oliviertassinari Hi! Download bug example and run npm i && npm run babel

TypeError: Cannot read property 'type' of undefined at memberExpressionRootIdentifier (D:\Example\node_modules\babel-plugin-transform-react-remove-prop-types\lib\index.js:105:39)

105 line in code while (memberExpression.node.object.type === 'MemberExpression') {

@av-dev Great, thank you!

[oliviertassinari]

It should be fixed with v0.4.20, thank you @lukeapage!

@Timer I believe this can now be closed thanks to https://github.com/facebook/create-react-app/commit/5c3f333837e4a296b1d6c7c9844cbb73516d3255 (was this commit pushed without a PR?) which uses [email protected].
