ionic cordova build android報錯

or on your system to install the gradle wrapper. Please include gradle

我查看本地配置文件

JAVA_HOME=`/usr/libexec/java_home`
CLASSPAHT=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$JAVA_HOME/bin:$PATH:/usr/local/bin:
export ANDROID_HOME=/Users/demeng/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools 
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:/usr/local/mysql/bin

export PATH="/usr/local/sbin:$PATH"

export GRADLE_HOME=/Applications/Android\ Studio.app/Contents/gradle/gradle-4.6/
export PATH=$PATH:$GRADLE_HOME/bin

明明有gradle啊！到gradle文件夾看一眼

$ cd /Applications/Android\ Studio.app/Contents/gradle/
$ ls
gradle-4.10.1	m2repository
$ cd gradle-4.10.1/
$ ls
LICENSE			getting-started.html	media
NOTICE			init.d
bin			lib
$ cd bin/
$ ls
gradle		gradle.bat

發現問題了！我gradle版本是寫死的，現在引用不到了。重新更新環境變量解決。
