Question

我在尝试运行项目时遇到此错误。

线程中的异常＆＃34; main＆＃34; java.lang.NoSuchMethodError： com.typesafe.config.Config.getDuration（Ljava /郎/字符串;）Ljava /时间/持续时间;

尝试清除ivy2缓存但没有成功。这就是我的构建sbt的样子：

Answer 1

这听起来像是一个类路径问题。您可能正在使用调用（使用）Typesafe Config的库，但路径中的Typesafe Config版本小于1.3.0。未找到的方法是在Typesafe Config 1.3.0中引入的。要查看运行时类路径，请确保这些语句是第一个执行的语句（即在应用程序崩溃之前）：

val cp = System.getProperty("java.class.path")
val sep = System.getProperty("path.separator")
cp.split(sep).foreach(println)

一旦您看到没有Typesafe Config 1.3.0，请将其添加为显式依赖项。

Answer 2

将TypeSafe 1.3.1添加为依赖项可能有所帮助，将其添加为依赖项Seq（）的一部分：

s = "The text contains {} alphabetic characters of which {} ({}) are 'e'".format(totalChars, numberOfe, percent_with_e)

print(s)
The text contains 5 alphabetic characters of which 5 (100.0) are 'e'
