如何用activator为Lagom创建一个新项目

Question

刚刚按照本指南下载并安装了最新版本的activator(1.3.10)。

我安装activator发行版的位置是可写的，activator-1.3.10/bin被添加到我的$PATH。

然后，我尝试创建一个像这样的新项目:

activator new test-project lagom-scala

…但我总是得到以下错误:

j3d@gonzo:~/Projects$ activator new test-project lagom-scala
Getting com.typesafe.activator activator-launcher 1.3.10 ...
