找不到JAVA_HOME Linux Mint：尝试使用Cordova构建Android应用

Question

I am trying to build an Android app with Cordova. Every time I run the command:

$ sudo cordova build android

it shows:

Error: Failed to find 'JAVA_HOME' environment variable. Try setting setting it manually.

My .bashrc is:

export ANDROID_HOME=/home/eduarda/Android/Sdk
export JAVA_HOME=/usr/lib/jvm/java-1.9.0-openjdk-amd64
export PATH=${PATH}:${JAVA_HOME}/bin

More details:

$ which java
/usr/bin/java

$ java -version
openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src)
OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)

$ echo $JAVA_HOME
/usr/lib/jvm/java-1.9.0-openjdk-amd64

$ echo $PATH

/home/eduarda/bin:/home/eduarda/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games://usr/lib/jvm/java-1.9.0-openjdk-amd64/bin

I don't know what to do, I think the error is with the java version, but I also don't know how to fix.

Answer 1

sudo is almost certainly clearing your environment. You need to set JAVA_HOME for root or for all users in, eg, /etc/profile or /etc/bashrc .

Alternatively, you can run the command as your normal user. Is sudo really necessary for Cordova?
