Answer 1

運行以下命令：

cordova build android --verbose

你可以得到這樣的輸出：

Running command: /usr/libexec/java_home
Command finished with error code 0: /usr/libexec/java_home
ANDROID_HOME=/Users/mj/phonegap/adt-bundle-mac-x86_64-20140321/sdk
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home
Running command: "/Applications/Android Studio.app/Contents/gradle/gradle-2.2.1/bin/gradle"
 -p /Users/mj/EduceMobile/app/platforms/android wrapper -b /Users/mj/EduceMobile/app/platfo
rms/android/wrapper.gradle

Error: spawn EACCES
    at exports._errnoException (util.js:1018:11)
    at ChildProcess.spawn (internal/child_process.js:319:11)
    at Object.exports.spawn (child_process.js:378:9)
    .....
    .....

注意這一行：

運行命令：“/Applications/Android Studio.app/Contents/gradle/gradle-2.2.1/bin/gradle”

這表明文件/Applications/Android Studio.app/Contents/gradle/gradle-2.2.1/bin/gradle存在權限問題。

要解決此問題，請對該文件授予適當的權限，使其可執行。

您可以運行以下命令：

sudo chmod +x /Applications/Android Studio.app/Contents/gradle/gradle-2.2.1/bin/gradle

這應該可以解決問題。
