我正在尝试创建一个超级简单的Webpack,它设置为从sass创建css。
我有文件:
index.html文件
入口.js
包.json
web包.config.js
CSS
-附录SCSS
index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<script type="text/javascript" src="bundle.js" charset="utf-8"></script>
</body>
</html>
条目.js:
require('./css/app.scss');
package.json文件包:
{
"name": "ls",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "webpack-dev-server"
},
"author": "",
"license": "ISC",
"devDependencies": {
"autoprefixer-loader": "^3.2.0",
"css-loader": "^1.0.0",
"node-sass": "^4.9.2",
"postcss-loader": "^2.1.6",
"sass-loader": "^7.1.0",
"style-loader": "^0.21.0",
"svg-sprite-loader": "^3.8.0",
"ts-loader": "^4.4.2",
"webpack-cli": "^3.1.0",
"webpack-dev-server": "^3.1.5"
}
}
webpack.config.js版本:
module.exports = {
entry: "./entry.js",
output: {
path: __dirname,
filename: "bundle.js"
},
module: {
loaders: [
{
test: /\.scss$/,
use: [ 'style-loader','css-loader','postcss-loader' ]
}
]
}
};
附录SCSS:
*{
color: red;
}
如果我跑步
npm start
我得到错误
Error: Cannot find module 'webpack'
如何设置此项以从app.scss文件输出CSS
更新
我安装了Webpack,现在出现以下错误
Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
- configuration.module has an unknown property 'loaders'. These properties are valid:
object { exprContextCritical?, exprContextRecursive?, exprContextRegExp?, exprContextRequest?, noParse?, rules?, defaultRules?, unknownContextCritical?, unknownContextRecursive?, unknownContextRegExp?, unknownContextRequest?, unsafeCache?, wrappedContextCritical?, wrappedContextRecursive?, wrappedContextRegExp?, strictExportPresence?, strictThisContextOnImports? }
-> Options affecting the normal modules (`NormalModuleFactory`).
