在Heroku上部署Foundation for Apps

Question

我试图在Heroku上部署使用“ Foundation for Apps”创建的应用程序，但没有成功。

gulpfile.js

// FOUNDATION FOR APPS TEMPLATE GULPFILE

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

// Copies user-created files and Foundation assets

  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']);
});

部署后，该应用程序成功构建，但有一个例外：

   showStack: false,

之后，当我打开浏览器时，看到的网站没有CSS样式。

https://fierce-escarpment-9048.herokuapp.com/assets/css/app.css 404未找到

我怀疑-由于sass的异常-没有生成CSS文件，因此-服务器无法访问。

有什么建议我可以解决吗？

您发布的特定错误实际上与JavaScript有关，最有可能与Node.js形式的服务器端JavaScript有关。 “ ENOENT”特定于Node.js的libuv组件（ https://github.com/joyent/node/blob/master/deps/uv/include/uv.h ）报告的错误。提供的链接与“没有这样的文件或目录”有关。

因此，您从错误logs / gulpfile.js中遇到的问题是，“默认”操作会启动由并发操作“ build”和“ server-start”组成的任务（gulpfile.js，第144行）。 “ build”任务本身是一个函数（第137行），该函数启动一个以“ clean”（第138行）开头的序列，我们应该返回该序列。 但是首先，“服务器启动” ...您的服务器确实启动：“正在启动'server：start'...在323毫秒后完成了'server：start'...服务器启动了http：// localhost：23921 ...状态从开始更改为开始。” 因此，您可以看到日志中捕获的“开始[x] ...完成[x]”对的匹配输出。 这很重要。

返回到“构建”任务。 这导致“干净”，随后是“复制”，“无礼”和“丑化”的并发动作； 正是在后一组中发生了您的问题。 首先，请注意我们有“在386毫秒后开始'clean'...完成'clean'”-再次，我们有匹配的对-并且必须在copy / sass / uglify之前进行clean。 这些是并发操作，您的问题是，在这些任务发生时，日志输出显然是随意编写的（原始重叠的构建任务和启动服务器任务也是如此）。 因此，我们可以看到所有“ copy”，“ sass”和“ uglify”开始……但只有“ sass”和“ uglify”完成！ 并且，我们有“复制”开始，以及其他不匹配/不相关的错误消息。 您的错误是由“复制”失败引起的，而不是由“无礼”引起的！ 您无法复制，并且（基于Node.js的）服务器正在引发“无此类文件或目录”。 抱歉，我无法解释其复制失败的内容（可能是'client'目录中的内容），但是它涉及到的内容缺失-甚至可能是简单的拼写错误的文件名，或类似的东西。 您可能应该仔细检查目录中的文件内容。

在本指南中找到了说明如何将Foundation for apps部署到heroku的指南，我已经尝试过了，并且看起来很吸引人。 希望能帮助到你。
