在Heroku上部署应用程序基础

Question

我正在尝试在Heroku上部署一个使用"Foundation for Apps“创建的应用程序，但没有成功。

Package.json：

gulpfile.js

// FOUNDATION FOR APPS TEMPLATE GULPFILE

// This file processes all of the assets in the "client" folder, combines them with the Foundation
// for Apps assets, and outputs the finished files in the "build" folder as a finished app.

// 3. TASKS
// - - - - - - - - - - - - - - -

// Cleans the build directory
gulp.task('clean', function(cb) {
  rimraf('./build', cb);
});

// Copies user-created files and Foundation assets
gulp.task('copy', function() {
  var dirs = [
    './client/**/*.*',
    '!./client/templates/**/*.*',
    '!./client/assets/{scss,js}/**/*.*'
  ];

  // Everything in the client folder except templates, Sass, and JS
  gulp.src(dirs, {
    base: './client/'
  })
    .pipe(gulp.dest('./build'));

  // Iconic SVG icons
  gulp.src('./bower_components/foundation-apps/iconic/**/*')
    .pipe(gulp.dest('./build/assets/img/iconic/'));

  // Foundation's Angular partials
  return gulp.src(['./bower_components/foundation-apps/js/angular/components/**/*.html'])
    .pipe(gulp.dest('./build/components/'));
});

// Compiles Sass
gulp.task('sass', function() {
  return gulp.src('client/assets/scss/app.scss')
    .pipe($.rubySass({
      loadPath: sassPaths,
      style: 'nested',
      bundleExec: true
    })).on('error', function(e) {
      console.log(e);
    })
    .pipe($.autoprefixer({
      browsers: ['last 2 versions', 'ie 10']
    }))
    .pipe(gulp.dest('./build/assets/css/'));
});

// Compiles and copies the Foundation for Apps JavaScript, as well as your app's custom JS
gulp.task('uglify', function() {
  // Foundation JavaScript
  gulp.src(foundationJS)
    .pipe($.uglify({
      beautify: true,
      mangle: false
    }).on('error', function(e) {
      console.log(e);
    }))
    .pipe($.concat('foundation.js'))
    .pipe(gulp.dest('./build/assets/js/'))
  ;

  // App JavaScript
  return gulp.src(appJS)
    .pipe($.uglify({
      beautify: true,
      mangle: false
    }).on('error', function(e) {
      console.log(e);
    }))
    .pipe($.concat('app.js'))
    .pipe(gulp.dest('./build/assets/js/'))
  ;
});

// Copies your app's page templates and generates URLs for them
gulp.task('copy-templates', ['copy'], function() {
  return gulp.src('./client/templates/**/*.html')
    .pipe(router({
      path: 'build/assets/js/routes.js',
      root: 'client'
    }))
    .pipe(gulp.dest('./build/templates'))
  ;
});

// Starts a test server, which you can view at http://localhost:8080
gulp.task('server:start', function() {
  $.connect.server({
    root: './build',
    port: process.env.PORT || 5000,
    livereload: false
  });
});

// Builds your entire app once, without starting a server
gulp.task('build', function() {
  sequence('clean', ['copy', 'sass', 'uglify'], 'copy-templates', function() {
    console.log("Successfully built.");
  })
});

// Default task: builds your app, starts a server, and recompiles assets when they change
gulp.task('default', ['build', 'server:start'], function() {
  // Watch Sass
  gulp.watch(['./client/assets/scss/**/*', './scss/**/*'], ['sass']);

  // Watch JavaScript
  gulp.watch(['./client/assets/js/**/*', './js/**/*'], ['uglify']);

  // Watch static files
  gulp.watch(['./client/**/*.*', '!./client/templates/**/*.*', '!./client/assets/{scss,js}/**/*.*'], ['copy']);

  // Watch app templates
  gulp.watch(['./client/templates/**/*.html'], ['copy-templates']);
});

当我部署时，应用程序成功构建，但有一个例外：

   showStack: false,

 Successfully built.

在那之后，当我打开浏览器时，我看到的是没有CSS样式的网站。

找不到https://fierce-escarpment-9048.herokuapp.com/assets/css/app.css 404

我怀疑-由于sass的异常- CSS文件没有生成，因此服务器无法访问。

有什么建议我可以修复它吗？

您发布的特定错误实际上与JavaScript相关，最有可能的是Node.js形式的服务器端JavaScript。"ENOENT“特定于从Node.js的libuv组件( https://github.com/joyent/node/blob/master/deps/uv/include/uv.h )报告的错误，正如您从提供的链接中所看到的，它与”没有这样的文件或目录“有关。

因此，您在error logs/gupfile.js中遇到的问题是，“默认”操作启动了由并发操作“构建”和“服务器启动”组成的任务(gulpfile.js，第144行)。“build”任务本身是一个函数(第137行)，它启动一个以“clean”(第138行)开始的序列，我们应该返回该序列。但首先，'server-start'...您的服务器确实启动了："Starting ' server :start'... Finished ' Server :start‘after 323 ms... Server started http://localhost:23921...State从starting更改为up。“因此，您可以看到在日志中捕获的"Starting x...fined x“对的匹配输出。这一点意义重大。

返回到“构建”任务。这会导致“清理”，然后是“copy”、“sass”和“uglify”的并发操作；正是在后一组中，您的问题才会发生。首先，请注意，我们有“开始‘清理’...在386ms后完成‘清理’”-同样，我们有匹配的对-清理必须在copy/sass/uglify之前进行。这些都是并发操作，您的问题是，记录的输出显然是在这些任务发生时随意编写的(最初的重叠构建和启动服务器任务也是如此)。所以，我们可以看到所有的'copy'，'sass‘和'uglify’开始...但是只有'sass‘和'uglify’结束！并且，我们有“复制”启动，以及其他不匹配/分离的错误消息。你的错误是由“复制”失败引起的，而不是“sass”！您复制失败，并且(基于Node.js的)服务器正在引发“没有这样的文件或目录”。对不起，我无法解释它复制失败的内容(可能是来自'client‘目录的内容)，但它涉及缺少的内容--甚至可能是一个简单的拼写错误的文件名，或者非常类似的东西。您可能应该仔细检查目录中的文件内容。

找到了this指南，其中解释了如何将应用程序的基础部署到heroku，我已经尝试过了，并且效果很好。希望能有所帮助。
