react-native, react and native-base version

react@15.4.0

Steps to reproduce (code snippet or screenshot)

just import any component will raise this error.

Screenshot of emulator/device

Is the bug present in both ios and android or in any one of them?

tested on iOS simulator

Closing this issue, as this doesn't seems to happen with the newer versions.

[luchillo17]

@shivrajkumar Please reopen, just happened to me with latest native-base version 2.1.5, but in Android.

@luchillo17 Could you post your package.json here

[luchillo17]

I'll do it tonight, also in the linked issue they say maybe i'm mixing incompatible React and React-Native versions:

@SupriyaKalghatgi I'm not at home, grab the package.json from the repo:

  }
}

I think it might be the ^ semver selector allowing me to mix React & React-native versions, what do you think?

[luchillo17]

I've been testing more, this is my output in a component with just React-Native's Text component:

And this is with Native-Base's Text component:

Please don't tell me Native-Base also needs to ensure some compatibility.

[SupriyaKalghatgi]

@luchillo17 yes may be
I have tried with these in my package.json and it goes well

"dependencies": {
    "native-base": "^2.1.5",
    "react": "16.0.0-alpha.12",
    "react-native": "0.45.1"
  },

[luchillo17]

I've just created a new project and tested, indeed it works, however my project is based on Typescript, might it be that?

[luchillo17]

@SupriyaKalghatgi Did you installed with npm or yarn?

[SupriyaKalghatgi]

@luchillo17 I did react-native init and then npm install native-base --save

[luchillo17]

I've started all over again, i'm using CRNA ejected to regular react native app.

Btw, have you noticed that react-native-cli package hasn't received an update since 2016-12-16 while CRNA since 2017-03-15?

The issue still exists when upgraded to react-native 0.48 from 0.43 along with upgrading the native base to 2.3.1 from 2.1.2 ..Is there a fix for this?

here is my package.json..

Same kind of error with React-native 49.2 and native-base 2.3.2 in a jest test giving:

ReferenceError: mapPropsToStyleNames is not defined
      at Object.<anonymous> (node_modules/native-base/dist/src/Utils/mapPropsToStyleNames.js:3:21)
      at Object.<anonymous> (node_modules/native-base/dist/src/basic/Text.js:7:27)
      at Object.<anonymous> (node_modules/native-base/dist/src/basic/SwipeRow.js:5:11)

the error is removed when i patch node_modules/native-base/src/Utils/mapPropsToStyleNames.js to:

i had to add to several dist files (DefaultTabBar.js, ScrollableTabBar.js):
var mapPropsToStyleNames=require("../../Utils/mapPropsToStyleNames");

import _ from "lodash";

export default function(styleNames, props) {
  const keys = _.keys(props);
  const values = _.values(props);

  _.forEach(keys, (key, index) => {
    if (values[index]) {
      styleNames.push(key);
    }
  });

  return styleNames;
};

Currently not available to create a PR for this, but this should give a hint to solve this.

I just got this error and it seems to be a case issue; my Utils folder was capitalized but the file referenced utils. I renamed the folder and all was well.
