错误介绍
这个错误是执行npm run build 编译打包时候出现的报错。
第一次看到的确很懵,告诉我这个问题件有个unkown word 有个不识别的单词,估计就是什么单词或者写错了吧。现在关键的是在dist目录下没有这个css文件。都没有文件生成。
解决方法
遇到这种情况,一个项目要是出现这种单词写错了,而且npm run dev 的时候也不报错。直接去一个文件一个文件的找肯定遭不住、所以找了很久的资料,终于看到一个大佬说修改一下webpack.prod.conf里的一段代码就可以了。然后重新打包就能打包成功。最后再到生成的css文件中去看到在多少行。再去对应的源文件里面修改。
// 在webpack.prod.conf中找到这个暂时注释掉。解决问题后再放开
//new OptimizeCSSPlugin({
// cssProcessorOptions: config.build.productionSourceMap
//? { safe: true, map: { inline: false } }
// : { safe: true }
//}),
最后解决问题后。及得把注释放开。我的问题是在样式里面用了
//注释
