Answer 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

Answer 2

我在android-studio-path / gradle / bin中找到了gradle可执行文件，并将其包含在我的$ PATH中。

Answer 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

Answer 4

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

1. go to https://gradle.org/install and download the version 4.0 of gradle,

2. mkdir opt/gradle

3. unzip -d /opt/gradle gradle-4.0-bin.zip

4. /* 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 

5. open another terminal and type gradle -v

6. return to cordova project and type cordova build
