Any suggestions, perhaps?
我也遇到了类似问题
"react": "16.2.0",
"react-native": "0.52.2",
报的错是:
Could not resolve all dependencies for configuration ':app:_debugApk'.
A problem occurred configuring project ':react-native-image-crop-picker'.
Could not resolve all dependencies for configuration ':react-native-image-crop-picker:_debugPublishCopy'.
Could not find com.github.yalantis:ucrop:2.2.1-native.

这是怎么会事? 有没有比较稳定的版本推荐?
follow readme file, there is section:
Add the following to your build.gradle's repositories section. (project build.gradle)
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
Was exactly done, you were too hurry to close an issue.
No prob, will use another lib.
something like that ????
repositories {
mavenLocal()
jcenter()
maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url "https://jitpack.io",
url "$rootDir/../node_modules/react-native/android"
}
}
I have a similar problem

@krionoah69 I updated android section in readme. https://github.com/ivpusic/react-native-image-crop-picker#android. So basically android/build.gradle allProjects section should be:
allprojects {
repositories {
mavenLocal()
jcenter()
maven { url "$rootDir/../node_modules/react-native/android" }
// jitpack repo is necessary to fetch ucrop dependency
maven { url "https://jitpack.io" }
}
}
@ivpusic I made the changes but now there was a bigger problem.
Add as it appears in the documentation (android / build.gradle):
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenLocal()
jcenter()
maven { url "$rootDir/../node_modules/react-native/android" }
// jitpack repo is necessary to fetch ucrop dependency
maven { url "https://jitpack.io" }
}
}
Add what refers to (android / app / build.gradle):
defaultConfig {
vectorDrawables.useSupportLibrary = true
applicationId "com.netbeepocket" // <-- This line.
minSdkVersion 16
targetSdkVersion 22
versionCode 2
versionName "1.0"
ndk {
abiFilters "armeabi-v7a", "x86"
}
}
And in the end I throw this error:

I have searched several post about the problem but I do not give with the solution.
