gradlew：command not found

1.gradlew：command not found

解决办法：

配置环境变量

    打开.bash_profile文件


    GRADLE_HOME=/Applications/Android\ Studio.app/Contents/gradle/gradle-5.1.1
    export GRADLE_HOME
    export PATH=${PATH}:${GRADLE_HOME}/bin



2.bash: ./gradlew: Permission denied

    chmod +x gradlew

3.env: bash\r: No such file or directory

    原因：该项目创建gradlew太旧了，复制一个 gradlew 文件过来即可
