尝试在Nashorn上运行browser.js时，<eval>中char类的空范围

标签： javascript java babeljs nashorn

我正在尝试在Nashorn中运行browser.js，在库中使用babel.transform来处理某些Isomorphic 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
    }
}

引发错误：

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

您需要确保使用正确的字符集UTF-8加载文件，以便正确解释它。
