在 Nashorn 上尝试 运行 browser.js 时 <eval> 中的 char class 中的空范围
empty range in char class in <eval> when trying to run browser.js on Nashorn
我正在尝试 运行 browser.js 在 Nashorn 中，在库中使用 babel.transform 一些同构 Webapp。
public BabelTransformer() throws ScriptException, IOException{
try
{
ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine nashorn = mgr.getEngineByName("nashorn");
nashorn.eval(getScript("com/facebook/babel/node_modules/babel-core/browser.min.js")); //The line 38
babel = (ScriptObjectMirror)nashorn.eval("babel");
invocable = (Invocable) nashorn;
}
catch(ScriptException | IOException e)
{
throw new Error(e); //The line 42
}
}
抛出错误：

这可能是 Nashorn 版本：https://github.com/babel/babel/issues/340
