[英]travis-ci build failure on grunt-contrib-imagemin task (Cannot ready property 'contents' of undefined
I am encountering an error during a travis-ci build for grunt-contrib-imagemin task... 在travis-ci构建grunt-contrib-imagemin任务时遇到错误...
Warning: Running "imagemin:dist" (imagemin) task
Fatal error: Cannot read property 'contents' of undefined
The grunt build works successfully on my local machine, however it fails when executed via travis-ci grunt构建在我的本地计算机上成功运行,但是通过travis-ci执行时失败
Gruntfile.js Gruntfile.js
imagemin: {
dist: {
files: [{
expand: true,
cwd: '<%= yeoman.app %>/images',
src: '{,*/}*.{png,jpg,jpeg,gif}',
dest: '<%= yeoman.dist %>/images'
}]
}
},

I have tried to determine if there is a syntax issue in how I am declaring src in the task... however, that does not appear to be the case... as I can successfully complete the build locally without error using a few different syntax styles, including the example provided by Grunt for grunt-contrib-imagemin 我试图确定在任务中声明src的方式中是否存在语法问题...但是,情况似乎并非如此...因为我可以成功地在本地完成构建,而不会出现一些错误语法样式,包括Grunt为grunt-contrib-imagemin提供的示例
Ref: https://github.com/gruntjs/grunt-contrib-imagemin 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
}]
Any thoughts or suggestions? 有什么想法或建议吗?
As a follow-up... 作为后续...
I have successfully moved passed this issue via a simple workaround by swapping out "grunt-contrib-imagemin": "^1.0.0" for "grunt-image": "^1.2.1" ... and subsequently updating my Gruntfile.js by replacing imagemin tasks with image tasks... 我已通过一个简单的解决方法成功解决了此问题,方法是将“ grunt-contrib-imagemin”:“ ^ 1.0.0”换为“ grunt-image”:“ ^ 1.2.1” ...,然后更新了我的Gruntfile。 js通过将imagemin任务替换为image任务...
Local builds and Travis CI builds are now succeeding with the same results. 本地版本和Travis CI版本现在都取得了成功,并取得了相同的结果。
Gruntfile.js Gruntfile.js
image: {
dist: {
files: [{
expand: true,
cwd: '<%= yeoman.app %>/images',
src: '{,*/}*.{png,jpg,jpeg,gif}',
dest: '<%= yeoman.dist %>/images'
}]
}
},
Sample build output below via local machine and via travis-ci: 以下是通过本地计算机和travis-ci生成的示例输出:
Running "image:dist" (image) task
✔ app/images/npmjs.png -> before=3.75 kB after=158 B reduced=3.59 kB(95.9%)
✔ app/images/bootstrap.png -> before=41.5 kB after=21.93 kB reduced=19.57 kB(47.2%)

This solution with grunt-image is working on my Angular + Firebase application... which I am deploying to Firebase Hosting via travis-ci and the deployment tool dpl. 这个带有grunt-image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将其部署到Firebase Hosting。
However I still haven't determined the solution to the original bug/issue with grunt-contrib-imagemin in travis-ci 但是我还没有在travis-ci中用grunt-contrib-imagemin确定原始bug /问题的解决方案
Any ideas would be much appreciated. 任何想法将不胜感激。 Cheers!
干杯!
