android - Meteor - 安装 android 平台找不到 ANDROID_HOME 变量

Question

当我尝试安装Android平台时，出现找不到环境变量ANDROID_HOME的错误，但如果回显，则证明它存在。

让我带你去吧:

1) 让我们创建一个新应用

dbugger@mercury:~/projects/meteor$ meteor create test 
Created a new Meteor app in 'test'.           

To run your new app:                          
  cd test                                     
  meteor                                      

If you are new to Meteor, try some of the learning resources here:
  https://www.meteor.com/learn                

2) 到目前为止，还不错。现在让我们安装安卓平台

dbugger@mercury:~/projects/meteor$ cd test/

dbugger@mercury:~/projects/meteor/test$ meteor add-platform android --verbose
Writing new config.xml

   While adding platform Android to Cordova project:

   Probably this is either a connection problem, or platform spec is incorrect.
   Check your connection and platform name/version/URL.

   (If the error message contains suggestions for a fix, note that this may not apply to the Meteor integration. You can try running again with the --verbose option to help diagnose the issue.)

3) 好吧，结果不是很好。让我们尝试使用 sudo

dbugger@mercury:~/projects/meteor/test$ sudo meteor add-platform android --verbose
Adding platform Android to Cordova project    
% Adding android project...                   
android: added platform                       
Checking Cordova requirements for platform Android

Your system does not yet seem to fulfill all requirements to build apps for Android.

Please follow the installation instructions here:
https://github.com/meteor/meteor/wiki/Mobile-Development-Install:-Android-on-Linux

Status of the requirements:                   
✓ Java JDK                                    
✗ Android SDK: Failed to find 'ANDROID_HOME' environment variable. Try setting setting it manually.
  Failed to find 'android' command in your 'PATH'. Try update your 'PATH' to include path to valid SDK directory.
✗ Android target: Android SDK not found. Make sure that it is installed. If it is not at the default location, set the ANDROID_HOME environment variable.
✗ Gradle: Could not find gradle wrapper within Android SDK. Could not find Android SDK directory.
  Might need to install Android SDK or set up 'ANDROID_HOME' env variable.

4)等等，什么？我确定已设置环境变量。让我们检查一下。

dbugger@mercury:~/projects/meteor/test$ echo $ANDROID_HOME
/home/dbugger/Android/Sdk

5) 我就知道!那为什么失败了……？我们再检查一下

dbugger@mercury:~/projects/meteor/test$ sudo meteor add-platform android --verbose


While adding platforms:
error: android: platform is already added

什么？!现在事实证明它最终安装了？这里发生了什么？我怀疑我的系统配置有很大错误，但我不确定是什么...

Answer 1

您正在使用 sudo!

1. 你可能不应该
2. 即使 ANDROID_HOME 变量是为您的当前用户定义的，并不意味着它也为 root 用户定义，这就是 sudo 调用的环境是。

我真的不建议对 meteor 使用 sudo。如果你能避免这种情况，那么它应该可以工作，你的问题就解决了。否则确保也为 root 用户定义 ANDROID_HOME 变量，或者只使用

sudo env ANDROID_HOME=[whatever you want it to be] meteor

相反。
