library.path中没有jansi

Question

根据Scala.js的说法，我有一个这个例子 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，指示缺少一个jansi库，但是我将jansi-1.11.jar添加到我的路径中。

我在某个地方尝试过几件事.我安装了Visual C++可再发行版或将fork in run := true添加到我的build.sbt中--但没有成功.

Answer 1

试着添加

"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

UPDATE：我下载了您的项目(分支autowire)，向build.sbt添加了依赖项，并向example.Server.main添加了以下行

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() )

对我来说很管用。你能把你的版本的代码上传到github吗？

Answer 2

您所得到的错误是运行时错误。所以，我认为你和构建路径无关。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 32。我认为这不是最好的解决方法，但在处理了3个小时后，它对我来说很好，可以找到一种方法来修改运行时路径以包含jansi.jar文件。
