Grunt usemin：在index.html文件中未替换连接的JavaScript文件
我从一个由yeoman生成的空项目开始，并尝试编辑Gruntfile.js以满足我的需求。
grunt构建任务读取我的index.html文件，并连接我的bower依赖项并生成.vendor.js文件。
我在工作流程中破坏了某些内容，现在usemin不会替换index.html文件中的标记，即使生成.vendor.js文件也是如此。
这是我的Gruntfile.js
'use strict';

5 个答案:
答案 0 :(得分：10)
我会回答我自己的问题：
我的useminprepre配置和usemin配置之间存在差异。
useminprepare写信给<%= yeoman.dist %>/public/views/edit/index.html
并且usemin正在阅读<%= yeoman.dist %>/views/edit/index.html
答案 1 :(得分：4)
出于某种原因，我遇到了同样的问题。在grunt build index.html期间我的grunt usemin:html未更新（但main.css和main.js输出正常）。我尝试了usemin:html 和工作。
所以我最终将grunt build移到{{1}}任务列表中的最后一个位置。
不知道为什么会这样，但它会让我到达我需要的地方。万一其他人可以发现这个有用。
答案 2 :(得分：1)
我有类似的问题。在我的情况下，除了凉亭里面的内容外，一切都按预期被替换：css或bower：js标签。看起来usemin无法取代凉亭评论所包围的内容。
答案 3 :(得分：1)
作为标准，请确保在sublime或IDE中选择Unix作为Line Endings。这可能是因为跨平台使用。
答案 4 :(得分：0)
我有同样的问题，grunt正在创建文件vendor.js和scripts.js，但它没有将它们插入index.html，最后它没有替换旧的脚本链接。它通过执行tk120404建议并修复构建过程来解决这个问题。
