React-Native (Build-Failed)

-

I am trying to build a react native app but I seem to always run across the same problem that a lot of developers are facing at the moment. After creating the app

  1. react-native init HelloWorld
  2. cd HelloWorld
  3. react-native run-ios (into the terminal)

an error such as this pops up and terminals the run: 

** BUILD FAILED **


The following commands produced analyzer issues:
	Analyze /Users/JemmaMarie/Documents/CareerCenter/Exercises/Ex_Files_Learning_React_Native/Exercise\ Files/Ch02/start/HelloWorld/node_modules/react-native/ReactCommon/yoga/yoga/YGNodeList.c

I have tried these solutions from stack overflow with no luck: Environment:

node: 8.2.1 Watchman: 4.7.0 xcode: 8.3.3 react-native-cli: 2.0.1 react-native: unknown

  1. Upgraded xCode Now version 8.3.2

  2. upgraded react native and ran react native run-ios again

  3. went to system preferences and selected the xcode version on the xcode IDE

  4. ive removed node_modules to look for the "typo" that another had found and ran react-native run-ios but still does not work

  5. tried removing the build folder ios/build by using rm -r and ran react-native run-ios

  6. tried another boilerplate create-react-native-app HelloWorld following the steps of https://github.com/facebookincubator/create-react-app

but get this error:

module.js:487
    throw err;
    ^

Error: Cannot find module 'semver'

    at tryModuleLoad (module.js:466:12)
    at Function.Module._load (module.js:458:3)

Did anyone find a pretty solid solution so far?

Thanks in advance.

ok i got same error, here i have post my anwser enter link description here

Before going to solution you should read the comments also ,So may be this can help you

So I decided to skip the Xcode route and use a different boilerplate and its corresponding Expo App.

https://github.com/react-community/create-react-native-app

open the file on your favorite IDE

and run: npm run ios on your terminal

you are still able to use the Xcode simulator though. it should automatically open :)

thanks for the time and the input for my prior issue!

Got a similar issue after having upgraded to watchman 4.7.0 using brew.

Looks like there's an issue in this new version of watchman: watchman issues 358.

At the end I solved my issue removing the content of the /usr/local/var/run/watchman/ folder.

I've met that error, I passed these steps and finally succeeded to build.

1) delete 'ios' and 'android' folder.
2) delete 'node_module'
3) npm i
4) react-native eject
5) react-native-git-upgrade  #this step is important
6) react-native run-ios

Meaning of `{}` for return expression

-
15 1 I found by accident that the following compiles: #include <string> #include <iostream> class A{ int i{}; std::string s{}; public: A(int _i, const std::string& _s) : i(_i), s(_s) { puts("Called A(int, const std::string)"); } }; A foo(int k, const char* cstr){ return {k, cstr}; // (*) } int main(){ auto a = foo(10, "Hi!"); return 0; } The line of interest is (*). I guess the function foo is equivalent to: A foo(int k, const char* str){ return A(k, cstr); } However, is there a special name for this mechanism in (*)? Or is it just the simple fact that the compiler knows which constructor to call due to the return type? ...

Get current scroll position of ScrollView in React Native

-
Is it possible to get the current scroll position, or the current page of a <ScrollView> component in React Native? So something like: <ScrollView horizontal={true} pagingEnabled={true} onScrollAnimationEnd={() => { // get this scrollview's current page or x/y scroll position }}> this.state.data.map(function(e, i) { <ImageCt key={i}></ImageCt> }) </ScrollView> Try. <ScrollView onScroll={this.handleScroll} /> And then: handleScroll: function(event: Object) { console.log(event.nativeEvent.contentOffset.y); }, Disclaimer: what follows is primarily the result of my own experimentation in React Native 0.50. The ScrollView documentation is currently missing a lot of the information covered below; for instance onScrollEndDrag is completely undocumented. Since everything here relies upon undocumented behaviour, I can unfortunately make no promises that this information will remain correct a ...
