attr/colorError not found error when using com.android.support:recyclerview-v7:26.0.0-beta2 : <p>I'm using Android Studio 3.0 Canary 4. I imported the recycler view library. Then it comes out the attr/colorError not found message.
This is app build.gradle:</p>

<pre><code>apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "com.robyn.myapplication"
        minSdkVersion 19
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    testImplementation 'junit:junit:4.12'
    implementation 'com.android.support:recyclerview-v7:26.0.0-beta2'
    implementation 'com.android.support:appcompat-v7:26.0.0-beta2'
}
</code></pre>

<p>Whenever I add the two libraries implementation 'com.android.support:recyclerview-v7:26.0.0-beta2' and 
    implementation 'com.android.support:appcompat-v7:26.0.0-beta2', it comes out this error message:
<a href="https://i.stack.imgur.com/78v0g.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/78v0g.jpg" alt="enter image description here"></a></p>

<p>I tried clean and rebuild, the error message is still there. I checked res/values/colors, the color values are there. Why I get this color error? If I want to use recycler view, what version of library should I import?</p>
