解决vue中gulp打包出错

更换cnpm重新安装gulp-imagemin

gulp.task('imagemin', function () {
    gulp.src('../dist/images/**/*').pipe(imagemin({ optimizationLevel: 3, progressive: true, interlaced: true }))
        .pipe(gulp.dest('../dist'+assetsPublicPath+'images')) 
});

目前找到的问题是,因为这个报错的,把这个去掉就好了.
写法也没问题 不知道是不是版本号的问题

希望各路大神帮忙解决~

7/20更新

这图片压缩呢 其实也可以不用压缩 项目还是能跑的
但是我可不想遗留bug,今天花了一下午时间还是被我翻翻找找,知道问题所在了

尝试解决问题的方法

按照网上说的环境变量配置,结果失败

升级版本gulp-imagemin 提示

[gulp-imagemin: Couldn't load default plugin xxx]

百度了一下,我大概知道怎么回事了,就是无法加载默认插件XXX
也就是说npm安装gulp-imagemin会丢失默认插件

更换yarn重新安装node-modules,结果还是失败
最后更换cnpm重新安装gulp-imagemin@3.2.0,结果成功
我的这个项目的gulp-imagemin版本号一直都是3.2.0
所以如果你使用的话,也要使用适合自己项目的版本号

这个原因我猜测大概就是这个gulp-imagemin的npm包损坏了
还是受到网络波动影响总是下载有毛病
要不就是我的网络环境有问题
可能里面的默认插件被某些东西限制了

总结一下:
问题就是很简单的问题,花了我不少时间...
所以,一点一点顺藤摸瓜,找到问题的位置,排查解决就可以了

加油~
