Maven Kurento Helloworld mvncomplie错误

我想根据本教程运行基于Kurento（WebRTC MediaServer）的应用程序：

运行这些代码后：

git clone https://github.com/Kurento/kurento-tutorial-java.git
cd kurento-tutorial-java/kurento-hello-world
git checkout 6.1.0
mvn compile exec:java

在最后一行mvn compile exec:java中，我遇到了以下错误：

我想知道问题的根源以及如何解决。谢谢

Java教程要求您在系统中安装

bower

，因为web客户端中需要的一些依赖项就是这样带来的。这就是这条信息的含义

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.2:exec (default) on project kurento-hello-world: Command execution failed. Cannot run program "bower" (in directory "/home/yashar/kurento-tutorial-java/kurento-hello-world"): error=2, No such file or directory -> [Help 1]

他在告诉你。使用

npm install bower-g

在您的系统中安装bower就足够了。您可能需要使用

sudo

发出该命令。如果是这种情况，我建议您阅读如何避免使用

sudo

全局安装节点包和修复权限。

无法运行程序“bower”是非常清楚的。你们有凉亭吗？没有。我将安装并报告结果。谢谢你，尝试过sudo npm安装bower-g，程序运行正常！非常感谢
