Android Can'；似乎无法从爱奥尼亚项目中生成APK

我是爱奥尼亚的新手，试图获得用于调试的apk，我在项目目录中使用了以下命令：

ionic cordova platform add android

我确实得到了“平台/安卓”目录

然后我用了：

ionic cordova build android

这就是我想要的：

     ionic-app-scripts build --target cordova --platform android

但是我没有得到承诺的\build\outputs\apk，有什么问题吗

更新：我安装了android studio并对其进行了更新，现在仍然可以使用

(node:12696) UnhandledPromiseRejectionWarning

更新：问题解决了，原来我有java10，它不能与android一起工作，只需安装java8就解决了问题

顺便说一句，我没有安装android sdk，如果这有什么区别

你已经回答了你自己的问题。 制作安卓APK

• 您需要JavaSDK1.8
• 具有最新构建工具和平台的Android SDK
• JAVA_HOME和ANDROID_HOME环境变量设置正确

---

此外，您还需要在Mac电脑上更新X代码才能创建IPA。

您的电脑中可能没有android环境变量。 如果您正在运行MAC，请尝试运行：

sudo export ANDROID_HOME=/<installation location>/android-sdk-macosx
sudo export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

sudo导出ANDROID\u HOME=//ANDROID sdk macosx
sudo导出路径=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform tools

如果您正在运行Linux，则：

export ANDROID_HOME=/<installation location>/android-sdk-linux
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

导出ANDROID\u HOME=//ANDROID sdk linux
导出路径=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform tools

如果您正在运行Windows，则以管理员身份打开命令提示符并运行：

set ANDROID_HOME=C:\<installation location>\android-sdk-windows
set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools 

设置ANDROID\u HOME=C:\\ANDROID sdk窗口
设置路径=%PATH%；%ANDROID_HOME%\tools；%ANDROID\u HOME%\平台工具

---

它将向您的系统中添加环境变量。

我下载了java和android sdk，但仍然出现以下错误：（节点：10748）未处理Promisejection警告：未处理的承诺拒绝。此错误源于在没有catch块的异步函数中抛出，或者拒绝未使用.catch（）处理的承诺。（拒绝id:1）能否粘贴整个错误消息？错误消息中是否没有更改？（节点：8236）未处理的PromisejectionWarning:未处理的承诺拒绝。此错误源于在没有catch块的异步函数中抛出，或者拒绝未使用.catch（）处理的承诺。（拒绝id:1）（节点：8236）[DEP0018]弃用警告：未处理的承诺拒绝被弃用。将来，未处理的承诺拒绝将使用非零退出代码终止Node.js进程。Ionic Framework:Ionic angular 3.9.2@Ionic/app脚本：3.1.10 Cordova:Cordova（Cordova CLI）：8.0.0 Cordova平台：无系统：NodeJS:v8.11.3（C:\Program Files\NodeJS\Node.exe）npm:6.3.0操作系统：Windows 10环境：ANDROID\u主页：非set@HasanAli转到Windows中的高级系统设置。然后导航到环境变量。在系统“ANDROID_HOME”中添加一个新变量，并将该值设置为SDK安装的位置。通常是C:\Users\username\AppData\Local\Android\sdk\Save环境变量。
