一个不常遇到的HbuilderX自动化测试运行问题

晚上10点左右，刚好说想研究一下uniapp项目中怎么进行自动测试，于是跟着插件的官方教程开始配置测试环境，写好了一个简单的测试脚本，然后图形化操作IDE运行测试，却报错了一大片错误信息，如下所示：

Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):

这个报错非常诡异，我最开始怀疑是node版本问题。我用nvm不断切换不同版本，甚至把HbuilderX的插件里面的node删除，用nvm使用的node创造软连接给它。然而并不解决问题，我google+sogou连续查阅相关问题，但是大部分都在说rebuild一下sass之类的。二node-sass本身安装也是正常的，我陷入了思维的死循环。最后熬夜到了2点，终于发现了：原来是通过淘宝cdn资源下载的binding.node文件有问题，去github上下载就是正确的了。github地址为：https://github.com/sass/node-sass/releases

以我本人为例，我下载了这个版本的文件https://github.com/sass/node-sass/releases/download/v7.0.1/darwin-x64-93_binding.node到/Applications/HBuilderX.app/Contents/HBuilderX/plugins/compile-node-sass/node_modules/node-sass-china/vendor/darwin-x64-93文件夹下

并把darwin-x64-93_binding.node文件重命名为binding.node

来来回回折腾，还是报错信息是最准确了，说的是binding.node is not a mach-o file ，说明可能该文件破碎或者无法识别，以后还是要相信科学，相信报错，少走弯路。
