无法构建Cordova Android应用程序 - 出现Java错误

Question

我正在使用离子,我跑ionic build android.出现以下错误.

:CordovaLib:compileDebugJava/Users/jasontanner/Documents/ion/fip/platforms/android/CordovaLib/src/org/apache/cordova/CordovaResourceApi.java:31: error: package org.apache.http.util does not exist

我已调整适当的文件以在Android 22 SDK上运行.除此之外,我没有对android代码进行任何其他更改.任何有关如何解决这个问题的帮助都很棒.谢谢!

尝试确保通过运行更新了所有库(离子,cordova等)npm update.如果这不起作用,我会检查你是否安装了最新的JDK.

最后尝试删除然后使用以下命令从项目中重新添加android平台

• ionic platform remove android
• ionic platform add android

如果你使用mac,你也可以尝试运行build命令,sudo例如sudo ionic build android.我已经安装了库(例如ionic和cordova)sudo.你可以在没有sudo的情况下看到npm throws错误.查看NVM选项,这是向前发展的最佳方式.
