使用 Scala 和 SBT 设置 IntelliJ

我正在尝试使用 scala 和 sbt 设置 intellij 进行开发。我已经在 IDE 上安装了 scala 和 SBT 插件。但是，当我尝试创建新的 scala 和 sbt 项目时，build.sbt 文件显示以下错误：

Cannot resolve symbol :=
Cannot resolve symbol name
Cannot resolve symbol version
Cannot resolve symbol scalaVersion

这是我的 build.sbt 文件，它是由 IDE 本身创建的：

name := "setup"

version := "1.0"

scalaVersion := "2.12.2"

以下是我创建项目所遵循的步骤：

第一步：文件->新建项目

第二步：从左侧面板中选择 Scala，在右侧面板中选择 SBT（即基于 SBT 的 Scala 项目），然后单击 Next。

第三步：填写项目详细信息，然后单击“完成”。 （Scala 版本 -> 2.12.2，SBT 版本 -> 0.13.13）

IntelliJ版本-IntelliJ IDEA 2017.1.3

Edit:

每当我尝试创建新项目时，都会收到以下错误：

** 所以我认为这是我的代理设置的问题，我肯定需要使用代理。有办法解决这个问题吗？？

任何帮助，将不胜感激。谢谢。
