再按照您的第16章安装好chisel等一系列环境后，编译您提供的最后的代码。总是再报错，我找到那个文件夹
您的代码：
libraryDependencies += "edu.berkeley.cs" %% "chisel3" % "3.2-SNAPSHOT"
libraryDependencies += "edu.berkeley.cs" %% "chisel-iotesters" % "1.2.+"
libraryDependencies += "edu.berkeley.cs" %% "chisel-dot-visualizer" % "0.1-SNAPSHOT"
libraryDependencies += "edu.berkeley.cs" %% "rocketchip" % "1.2"
我修改的代码：
libraryDependencies += "edu.berkeley.cs" %% "chisel3_2.12" % "3.5-SNAPSHOT"
//libraryDependencies += "edu.berkeley.cs" %% "firrtl_2.12" % "1.5-SNAPSHOT"
//libraryDependencies += "edu.berkeley.cs" %% "chisel-dot-visualizer" % "0.1-SNAPSHOT"
//libraryDependencies += "edu.berkeley.cs" %% "chisel3-core_2.12" % "3.5-SNAPSHOT"
对edu.berkeley.cs中的文件名进行修改，结果发现还是编译不过，4个语句的报错为同种类型的，我的edu.ber文件夹中没有iotester等文件。
不知道是哪里出了问题
