当我使用bash'dir'检查heroku控制台时，angular应用程序构建后的dist/koko和friend文件夹就在那里。这很奇怪，因为我在angular 4中使用了相同的选项，排除了预安装中的@angular devkit/build angular。我还检查了heroku日志，没有发现任何错误。您的NPM脚本没有任何将内容移动到特定文件夹的逻辑 这意味着您的页面应该位于
dist/index.htmldist/koko和friend/index.html请同时发布
angular.jsonangular.jsonapp.use（express.static（path.join（uu dirname，/dist'））
与
app.use（express.static（path.join（uu dirname，'/dist/koko and friend'））您可以在angular.json中看到路径是dist/koko和friend/index.html。它是由Angular CLI自动创建的。我看到了是的。但是是自动创建的吗？我怀疑是这样。。。您的dist文件夹是否包含此文件夹？此外，由于使用沙盒（HeloCu），请考虑在脚本中显式输出。这意味着在您的package.json中，可以尝试以下操作：“build”：“ng build--prod--output path koko and friend”
，“postinstall”：“npm run build”
是的，路径是在执行此命令“ng new koko and friend”后自动创建的，当我检查angular.json构建路径时，就是这样。是的，dist文件夹包含koko和friend文件夹，这是应用程序的名称。您是否尝试使用显式输出？怎么回事？显式输出对heroku也不起作用，但我已经解决了。我在Angular.json中修改了自动创建的路径，并没有使用dist/koko和friend，而是使用dist only并将整个文件移动到dist文件夹，删除了koko和friend文件夹。我还使用angular v6创建了一个新的angular项目，构建路径非常类似于“dist/project name”。它在heroku中部署时也是空白的，而且日志或部署中也没有错误，因此服务器可以找到index.html。这太奇怪了。
