react-native \ react.gradle'不存在

Question

我使用react native创建了一个应用程序，我正在尝试生成apk。在http://facebook.github.io/react-native/docs/signed-apk-android.html#content的文件中完成后。发生错误，它表示无法读取脚本react-native \ react.gradle'，因为它不存在。

这是错误

apply from: "../../node_modules/react-native/react.gradle"

/**
 * Set this to true to create two separate APKs instead of one:
 *   - An APK that only works on ARM devices
 *   - An APK that only works on x86 devices
 * The advantage is the size of the APK is reduced by about 4MB.
 * Upload all the APKs to the Play Store and people will download
 * the correct one based on the CPU architecture of their device.
