运行`tns build android`时出现错误`spawn ./gradlew ENOENT`

Question

我从 nativescript 开始。我正在尝试构建一个 hello world 应用程序来测试它。但是，当我运行它时，我得到一个退出状态 127 for command not found。

这是我尝试构建的方法：

[ahmed@localhost hello]$ tns build android
Executing before-shouldPrepare hook from /home/ahmed/PycharmProjects/hello/hooks/before-shouldPrepare/nativescript-dev-webpack.js
Skipping prepare.
Building project...
Gradle build...
spawn ./gradlew ENOENT
[ahmed@localhost hello]$ echo $?
127
[ahmed@localhost hello]$ 

如果我跑tns doctor，一切似乎都好

[ahmed@localhost hello]$ tns doctor
