chisel编译错误:对象插件不是包chisel3.internal的成员

Question

我正在用一个小的试验项目学习chisel3。

我完成了代码，修复了编译过程中的几个语法问题，然后，它报告了一个错误，但没有指明错误文件和行号。

$ sbt test

什么意思？请帮帮忙。

Answer 1

我刚刚发现，在build.sbt中更改了chisel3版本后，这个错误就消失了。

    libraryDependencies ++= Seq(
      "edu.berkeley.cs" %% "chisel3" % "3.4.3",
//      "edu.berkeley.cs" %% "chisel3" % "3.2.6", // this one generate plugin error above
      "edu.berkeley.cs" %% "chiseltest" % "0.3.3" % "test",
      "edu.berkeley.cs" %% "rocketchip" % "1.2.6"

之前我从3.4.3更改为3.2.6，因为sbt警告

[warn] There may be incompatibilities among your library dependencies; run 'evicted' to see detailed eviction warnings.

我运行sbt evicted，它告诉我rocketchip 1.2.6应该使用chisel3 3.2.6。

也许有人能解释清楚。
