android - Gradle同步失败-无法确定当前字符

Question

我目前无法建立专案。

Current error:

Script '/Users/pimzonneveld/the-red-corner/veganific-mobile-app/node_modules/@react-native-community/cli-platform-android/native_modules.gradle' line: 191
Gradle sync failed: Unable to determine the current character, it is not a string, number, array, or object
            The current character read is 'i' with an int value of 105
            Unable to determine the current character, it is not a string, number, array, or object
            line number 1
            index number 0
            info Run "react-native --help" to see a list of all available commands.
            ^ (6 s 386 ms)

尝试删除无效的 app\build\intermediates\signing_config\debug\out\signing-config.json。

尝试删除 .gradle和 .idea并与Android Studio重新同步。没用

尝试删除并重新安装 @react-native-community软件包

尝试删除

Android Studio是 V3.5Gradle是 V5.4.1
编辑

当前失败的文件是下面发布的 native_modules.gradle:

Answer 1

它在第191行失败，这是:
def json = new JsonSlurper().parseText(reactNativeConfigOutput)
我认为您要解析的JSON无效。

可能与this issue有关
