我知道使用webpack和webpack-dev-server構建的區別在於後者輸出和服務於內存，而前者將輸出創建爲磁盤並且不會啓動快遞服務。加載webpack-dev-server的問題加載
我的問題是，我的webpack配置工作正常，如果我通過webpack運行它，然後運行webpack-dev-server，但後者看着它，當發生更改時，它們不會反映在輸出中因爲它應該隻影響內存中的內容）。但是，如果我刪除了磁盤上的構建文件，並且不首先與webpack綁定，我無法使webpack-dev-server加載Angular應用程序（頁面空白並顯示「無法獲取/」）。
半工作方法
此作品（但並不理想，因爲我建立這一切兩次）：
- 創建指定的輸出和devserver選項的WebPack配置。
- 運行npm命令「
npm run webpack -- --config appConfigs/webpack.dev.js --progress --profile && npm run webpack-dev-server -- --config appConfigs/webpack.dev.js --open --progress --profile --inline」 - 它建立到輸出目錄，然後webpack-dev-server啓動這些文件，它運行順暢。
僅使用的WebPack-DEV-服務器
這看起來不正確。 webpack-dev-server的全部重點是從內存中提供服務，所以它根本不需要從輸出文件讀取數據。如果我按照以下步驟進行操作，則不起作用：
- 刪除以前生成的輸出文件夾。
- 運行故宮命令「
npm run webpack-dev-server -- --config appConfigs/webpack.dev.js --open --progress --profile --inline」 - 當瀏覽器加載起來，用錯誤招呼「無法GET /」
這裏是的WebPack-dev的服務器輸出與問候到內容位於： 項目運行在http://localhost:9000/ 的WebPack輸出從/ 內容不從的WebPack是由C送達：\某某\ DIST
所以，我希望，當它加載了，它會找到的index.html在http://localhost:9000，但我取而代之的是「無法GET /」。
現在，另一個SO帖子指出，由於沒有編寫任何文件，我需要使用像HtmlWebpackPlugin這樣的插件來確保它已正確創建並可用於webpack，但似乎沒有解決問題。
webpack.dev.config內容
這裏是我的webpack.dev.config（注意這個文件工作正常，如果我的WebPack通常捆綁，如果我用的WebPack捆綁提供精美，然後運行的WebPack-dev亡服務器）。

所以，它看起來像它的工作原理，但我無法瀏覽到任何與得到「無法獲取{無論我試圖去}「
在此期間，我可以運行半工作方式，但它會捆綁它通過webpack，輸出到目錄，然後啓動webpack-dev-serv呃來自該目錄中的文件，這不像它應該做的那樣（這需要兩倍的時間，因爲它捆綁了兩次）。
我錯過了什麼？
