Question

我有一个根据this example的Scala.js Web应用程序，我正在尝试调用第三方Java库。

我收到一个奇怪的错误，表示缺少jansi lib，但我将 jansi-1.11.jar 添加到我的路径中。

我尝试了一些在某处提出的事情......我安装了Visual Studio C ++ Redistributables或将fork in run := true添加到我的 build.sbt - 但没有成功......

Answer 1

尝试添加

"org.fusesource.jansi" % "jansi" % "1.11",

到build.sbt

的第29行

https://github.com/lihaoyi/workbench-example-app/blob/autowire/build.sbt#L29

更新：我下载了您的项目（分支autowire），将依赖项添加到build.sbt并将以下行添加到example.Server.main：

import org.fusesource.jansi.AnsiConsole
import org.fusesource.jansi.Ansi._
import org.fusesource.jansi.Ansi.Color._

AnsiConsole.systemInstall()
println( ansi().eraseScreen().fg(RED).a("Hello").fg(GREEN).a(" World").reset() )

它对我有用。你能将你的代码版本上传到github吗？

Answer 2

您获得的错误是运行时错误。所以，我认为你与构建路径无关。如果您在Windows中工作，请尝试将jansi.dll安装到任何java.library.path目录中;例如c：/ windows / system32。我想这不是最好的解决方法，但在处理3个小时后找到改变运行时路径以包含jansi.jar文件的方法后，它对我来说很好。

在library.path
