ionic 3 cli 'ionic cordova run android' 命令抛出错误

Question

我将 cli 更新为 ionic 3 版本，当我运行

ionic cordova run android

在 android 模拟器中构建 apk 文件和运行我遇到了这个错误

[ERROR] An error occurred while running cordova run android (exit code 1).

我已经尝试过但无济于事： 1. 删除 android studio 并重新安装。 2. 运行这些命令

cordova platform rm android
cordova platform add android
npm cache clear

更新 android studio 中的 sdk

没有什么能真正帮助解决这个问题。

Answer 1

将 Android Studio 的 Gradle 的位置（例如 /usr/local/android-studio/gradle/gradle-3.2/bin 对应 linux）添加到您的 PATH 环境变量

Answer 2

我就是这样解决这个问题的。

下载gradle最新版bin文件本linklink to download gradle
将 winzip 文件解压到 java 文件夹中（例如 C:\Program Files\Java\jdk1.8.0_101\gradle-3.5）
转到我的电脑右键单击 -> 属性。
然后进入左侧菜单中的高级系统设置。
advances -> environment Variables 然后 select Path.
添加名为 %GRADLE_HOME%/bin

Answer 3

我遇到了同样的问题运行下面的命令应该可以正常工作。

ionic cordova 运行 android --livereload

Answer 4

对我来说，这解决了问题：

ionic cordova platform rm android 
ionic cordova platform add android

Answer 5

我也遇到了同样的问题，现在按照以下步骤解决了问题

下载了 gradle zip 版本并解压缩到路径 user\<username>\android-sdk\gradle
在环境变量中配置相同的路径，如GRADLE_HOME和path
