发布ASP.NET Core项目时出错

Question

我有一个ASP.NET Core RC1项目不再正确发布（请参见下面的发布跟踪输出）。在project.json中定义的预发布脚本中的gulp min任务正在导致该错误。如果我删除它，项目会正确发布，但不会缩小js和css文件。

"scripts": { 
    "prepublish": [ "npm install", "bower install", "gulp clean", "gulp min" ] 
} 

我已经把另一个Web项目的解决方案，并发布没有错误，所以我认为，消除环境问题。但是，我看不出测试项目和失败测试项目之间的任何实质性差异。

我也删除了失败项目中的node_modules文件夹，强制Visual Studio再次下载所有npm包。

最后，我在VS命令提示符下面的trace中运行了dnu publish命令，这也失败了。

任何人都可以告诉我什么问题是从下面的错误跟踪，请？

更新 的gulp min任务包含下面的代码（从gulp.js）：

gulp.task("min:js", function() { 
    return gulp.src([paths.js, "!" + paths.minJs], { base: "." }) 
     .pipe(concat(paths.concatJsDest)) 
     .pipe(uglify()) 
     .pipe(gulp.dest(".")); 
}); 

UPDATE2：event.js

var rx = require("rx"); 

function normalizeKeypressEvents(args) { 
    return { value: args[0], key: args[1] }; 
} 

module.exports = function(rl) { 
    return { 
    line: rx.Observable.fromEvent(rl, "line"), 

    keypress: rx.Observable.fromEvent(rl, "keypress", normalizeKeypressEvents), 

    normalizedUpKey: rx.Observable.fromEvent(rl, "keypress", normalizeKeypressEvents).filter(function (e) { 
     return e.key && (e.key.name === "up" || e.key.name === "k"); 
    }).share(), 

    normalizedDownKey: rx.Observable.fromEvent(rl, "keypress", normalizeKeypressEvents).filter(function (e) { 
     return e.key && (e.key.name === "down" || e.key.name === "j"); 
    }).share(), 

    numberKey: rx.Observable.fromEvent(rl, "keypress", normalizeKeypressEvents).filter(function (e) { 
     return e.value && "123456789".indexOf(e.value) >= 0; 
    }).map(function(e) { 
     return Number(e.value); 
    }).share(), 

    spaceKey: rx.Observable.fromEvent(rl, "keypress", normalizeKeypressEvents).filter(function (e) { 
     return e.key && e.key.name === "space"; 
    }).share(), 

    }; 
}; 

Answer 1

原来，这是一个一块应用程序JavaScript是causin g“gulp min”任务失败。罪魁祸首是以下看似无害的一段代码：

$http.get(uri, { params: { config } }).then(function (data) { 
    return data; 
}); 

我仍然无法看到任何问题，但随着代码变得多余，我删除，并解决了这个问题的方式。

Answer 2

我得到相同的问题（即使在相同的行号）。保罗自己的回答给了我一个线索，要仔细看看我自己的.js

我注释掉了大部分文件，然后逐步取消注释了代码块，直到错误恢复。

而这个有问题的代码？ 这是使用模板串线是问题：

rtUl.insertAdjacentHTML("beforeend", `<li>${el.toString()}</li>`); 

更改回简单的串连工作：

rtUl.insertAdjacentHTML("beforeend", "<li>" + el.toString() + "</li>"); 

看来，丑化无法读取字符串模板（还）。
