发布ASP.NET Core项目时出错

时间：2016-02-18 08:04:41

标签： npm visual-studio-2015 asp.net-core

我有一个不再正确发布的ASP.NET Core RC1项目（请参阅下面的发布跟踪输出）。 gulp min中定义的预发布脚本中的project.json任务导致错误。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" ]
}

我已经在解决方案中添加了另一个Web项目，并且发布时没有错误，所以我认为这可以消除环境问题。但是，我看不出测试项目和失败的项目之间有什么实质性的差别。

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

最后，我在VS命令提示符下面的跟踪中运行了dnu publish命令，但也失败了。

有人可以告诉我下面的错误跟踪问题是什么吗？

更新 gulp min任务包含以下代码（来自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(),

  };
};

原来这是一个应用程序javascript导致＆＃34; gulp min＆＃34;任务失败。罪魁祸首是以下看似无害的代码：

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

我仍然无法看到它的任何问题，但随着代码变得多余，我删除了它并以这种方式解决了问题。

我遇到了同样的问题（即使在相同的行号上）。保罗自己的回答给了我一个线索，仔细看看我自己的.js

我注释掉了大部分文件，然后是逐步取消注释的代码块，直到错误消失为止。

违规代码？ 使用模板字符串的这一行是问题所在：

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

将其更改回简单的连接工作：

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

似乎uglify无法读取字符串模板。
