安装react-native-vector-icons后的React-native应用程序构建问题

Question

I have a problem in a react-native project after install react-native-vector-icons and try to build android app in the emulator. I'm working on Windows. I installed the library and linked it as said in the manual, but I think I have a dependency problem.

C:\react-native run-android
Scanning folders for symlinks in C:\Users\user\Source\reactnative\myapp\node_modules (43ms)
Starting JS server...
Building and installing the app on the device (cd android && gradlew.bat installDebug)...

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\user\Source\reactnative\myapp\node_modules\react-native-vector-icons\android\build.gradle' line: 4

* What went wrong:
A problem occurred evaluating project ':react-native-vector-icons'.
> Could not find method google() for arguments [] on repository container.

Installed versions: "react": "16.3.1", "react-native": "0.55.4", "react-native-elements": "^0.19.1", "react-native-vector-icons": "^6.0.2",

Can somebody help me?

Answer 1

Your best option is to either downgrade the vector-icons version or upgrade react-native + react versions.

Another option is to manually update your gradle and gradle-wrapper versions in the android project.

So update the gradle version in the top-level gradle file:

Usually located here: project_name/android/build.gradle

Change to:

dependencies {
  classpath 'com.android.tools.build:gradle:3.2.1'
}

And also the gradle-wrapper:

Usually located here: project_name/android/gradle/wrapper/gradle-wrapper.properties

Change to:

distributionUrl=https\\://services.gradle.org/distributions/gradle-4.10.2-all.zip

Answer 2

1. Uninstall vector-icons (remove wire-react-vector-icons-native)
2. Delete the folder node_modules
3. Then yarn install
4. Type this command yarn add react-native-vector-icons
5. Then this react-link native command react-native-vector-icons
6. Then this command reage-nactive run- android 7 then react-native start --reset-cache

These steps worked for me

Answer 3

I had the same errors, the following steps worked for me:

1.change the code in android/build/gradle.

 buildscript {
        repositories {
            jcenter()
            google()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.3.1'

            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        google()
    }
}

In the above code, google() is added in buildscript and allprojects and classpath gradle version is replaced by the gradle version of classpath in ..\\node_modules\\react-native-vector-icons\\android\\build.gradle (mine is 3.3.1, yours can be different).

2. in android/gradle/wrapper/gradle-wrapper.properties, modify the distributionUrl:

    distributionUrl=https\\://services.gradle.org/distributions/gradle-4.10.1-all.zip 

Version of the above library is 4.10.1, The minimum version of the above library required by gradle version 3.3.1 is 4.10.1, so I installed gradle-4.10.1-all.zip in my project.
