我在 Intellij IDEA Ultimate 上使用 sbt 在 SDK 16 上有一個 Scala 專案。這是我的build.sbt檔案：
name := "meteo-france-client"
version := "0.1"
scalaVersion := "3.0.0-M2"
libraryDependencies = "org.scalatest" %% "scalatest" % "3.3.0-SNAP3" % Test
我有一個src/scala/test/MainTest.scala包含以下代碼的測驗檔案：
import org.scalatest.funsuite.AnyFunSuite
class MainTest extends AnyFunSuite {
test("Example") {
assert(1 == 1)
}
}
請注意，在 IDE 中，import 陳述句的“scalatest”一詞以及“test”函式名稱顯示為紅色，并被告知找不到，即使我可以編譯專案。雖然我能夠編譯，但我無法運行測驗。實際上，當我運行sbt test它時，它給了我以下錯誤：

有沒有人知道為什么我會收到這個錯誤？
我可能是錯的，但看起來 Scala 3.0.0-M2 擺脫了這個scala.collection.immutable.List類。
uj5u.com熱心網友回復：
感謝 @stefanobaghino ，事實證明我只需要更改我的 build.sbt 檔案：
name := "meteo-france-client"
version := "0.1"
scalaVersion := "3.0.2"
libraryDependencies = "org.scalatest" %% "scalatest" % "3.2.10" % Test
因此從 Scala 3.0.0-M2 切換到 Scala 3.0.2 和 Sclatest 3.3.0-SNAP3 到 Scalatest 3.2.10。
