錯誤介紹
這個錯誤是執行npm run build 編譯打包時候出現的報錯。
第一次看到的確很懵，告訴我這個問題件有個unkown word 有個不識別的單詞，估計就是什么單詞或者寫錯了吧。現在關鍵的是在dist目錄下沒有這個css文件。都沒有文件生成。
解決方法
遇到這種情況，一個項目要是出現這種單詞寫錯了，而且npm run dev 的時候也不報錯。直接去一個文件一個文件的找肯定遭不住、所以找了很久的資料，終於看到一個大佬說修改一下webpack.prod.conf里的一段代碼就可以了。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。再去對應的源文件里面修改。
// 在webpack.prod.conf中找到這個暫時注釋掉。解決問題后再放開
//new OptimizeCSSPlugin({
// cssProcessorOptions: config.build.productionSourceMap
//? { safe: true, map: { inline: false } }
// : { safe: true }
//}),
最后解決問題后。及得把注釋放開。我的問題是在樣式里面用了
//注釋
