ionic 2：离子运行android显示错误

Question

当我在ionic 2应用程序中运行“ ionic run android”或“ ionic build android”时出现错误，这是我得到的错误。 我只是尝试在android的模拟器中看到我的应用程序。 我试图做新的ionic 2项目，但这是同样的问题。

Answer 1

最近，这与ionic和A2并解决main.prod.*成为一个常见问题main.prod.*尝试为该项目更新应用程序脚本。

npm install @ionic/app-scripts@latest

之后，您的错误消息应该更改，实际上是导致构建崩溃的原因。 如果错误消息更改，请使用新消息更新您的问题。

Answer 2

关闭所有离子文件夹，然后进行服务或练习。 再试一次， ionic cordova build android 。

Answer 3

您的系统中存在路径设置问题。

使用CMD第一次检查npm版本：npm -v

如果显示版本号，则使用下面的代码，否则首先设置您的npm路径，则可以使用gitbash cmd，nodejs cmd

尝试使用

ionic cordova run android 

要么

ionic cordova platform remove android

ionic cordova run android

如果您有MAC系统，必须使用sudo之类的

sudo ionic cordova run android

Answer 4

首先，在package.json文件中检查Android的版本。

现在使用此命令删除平台（ionic cordova platform rm android）

之后，使用此命令添加平台（ionic cordova platform add

android@6.4.0）。 如果7.0.0不是稳定版本，请使用6.4.0

现在，运行此命令（ionic cordova运行android）或在mac中（sudo ionic cordova运行android）

Answer 5

试试下面的命令

$ cordova clean android
$ cordova build android
$ ionic cordova build android
