回答1:

Just figured out the problems,

I just remove Gradle and run below code

sudo apt-get remove gradle

And ran

ionic run android

Its install Gradle itself, The problem was solved

回答2:

I found the gradle executable in android-studio-path/gradle/bin and included it to my $PATH.

回答3:

Go to the site https://gradle.org/releases, download the lastest version in some folder. Unpack the zipfolder and create a symbolic link: sudo ln -sf /PATH-TO-BIN-FOLDER/gradle /usr/bin/gradle

回答4:

are you using Jessie Debian or ubuntu this will be right,

go to https://gradle.org/install and download the version 4.0 of gradle,
mkdir opt/gradle
unzip -d /opt/gradle gradle-4.0-bin.zip

/* I using Debian Jessie then I do :

if [ -d "/opt/gradle/gradle-4.0" ]; then
    export GRADLE_HOME="/opt/gradle/gradle-4.0"
    PATH="$PATH:$GRADLE_HOME/bin"
fi

open another terminal and type gradle -v
return to cordova project and type cordova build
