我正在設置一個基本的Webpack安裝,並希望使用PostCSS和PreCSS插件在@imported文件中自動瀏覽器重新載入預處理的CSS。目前,如果我修改並保存@imported文件,瀏覽器不刷新(下例中的body.css)。如果我然後保存根引用的CSS文件(styles.css),則瀏覽器刷新並且還反映對@imported文件所做的任何更改。Webpack和Precss不會在@import文件上重新載入
我嘗試過使用可配置的webpack-dev-server,並使用server.js。我試過沒有和熱模型重新加載(HMR)安裝。
有沒有辦法讓webpack觀看@imported CSS文件,還是我從根本上缺少些什麼?

個entry.js
require("./styles.css");
document.write(require("./content.js"));
styles.css的
@import "body.css";
body {
/*background: yellow; */
font-size: 30px;
}
div {
display: flex;
}
body.css
$color: yellow;
body {
background: $color;
}
div {
color: white;
a {
color: green;
}
}
div {
display: flex;
}
另外需要注意的是,如果我使用HMR並保存根styles.css,我會收到以下消息:以下模塊不能熱更新:(他們需要完全重新加載!),我必須刷新頁面。如果我不使用HMR,那麼它只會在保存根styles.css時刷新。 – mummybot
