我在 travis-ci 构建 grunt-contrib-imagemin 任务时遇到了错误......
Warning: Running "imagemin:dist" (imagemin) task
Fatal error: Cannot read property 'contents' of undefined
grunt 构建在我的本地机器上成功运行，但是通过 travis-ci 执行时会失败
咕噜咕噜.js
imagemin: {
dist: {
files: [{
expand: true,
cwd: '<%= yeoman.app %>/images',
src: '{,*/}*.{png,jpg,jpeg,gif}',
dest: '<%= yeoman.dist %>/images'
}]
}
},
本地咕噜声构建（输出）

我试图确定我在任务中声明 src 的方式是否存在语法问题......然而，情况似乎并非如此...因为我可以使用几种不同的语法样式在本地成功完成构建而不会出错，包括 Grunt 为 grunt-contrib-imagemin 提供的示例
参考： https://github.com/gruntjs/grunt-contrib-imagemin
dynamic: { // Another target
files: [{
expand: true, // Enable dynamic expansion
cwd: 'src/', // Src matches are relative to this path
src: ['**/*.{png,jpg,gif}'], // Actual patterns to match
dest: 'dist/' // Destination path prefix
}]
有什么想法或建议吗？
作为后续...
我已经通过一个简单的解决方法成功地解决了这个问题，将"grunt-contrib-imagemin"："^1.0.0"换成了"grunt-image"："^1.2.1"......并随后更新我的 Gruntfile.js通过将 imagemin 任务替换为图像任务......
本地构建和 Travis CI 构建现在以相同的结果成功。
咕噜咕噜.js
image: {
dist: {
files: [{
expand: true,
cwd: '<%= yeoman.app %>/images',
src: '{,*/}*.{png,jpg,jpeg,gif}',
dest: '<%= yeoman.dist %>/images'
}]
}
},
下面通过本地机器和 travis-ci 进行的示例构建输出：

这个带有咕噜声图像的解决方案正在我的 Angular + Firebase 应用程序上运行......我正在通过travis-ci和部署工具dpl部署到Firebase Hosting。
但是我仍然没有确定 travis-ci 中 grunt-contrib-imagemin 的原始错误/问题的解决方案
任何想法将不胜感激。 干杯！
-
删除
node_modules -
将
package.json更改为使用"grunt-contrib-imagemin"："1.0.0"和"vinyl-fs"："2.3.1" - 做
npm install
