package.json

  "main": "index.js",
  "scripts": {
    "dev": "webpack --mode development ./src/index.js --output ./static/frontend/main.js",

发现在 ./node_modules/.bin/ 我只有 loose-envify -> ../loose-envify/cli.js*我读了这个问题 Webpack command not found ，但不明白如何解决我的错误。

Answer 1

您正在尝试使用 webpack 但它未在 devDependencies 下列出。

在您的终端中，运行 npm install --save-dev webpack 然后重试。

我可能不是 100% 正确地使用该命令，因为我通常使用 yarn 并且命令是 yarn add --dev webpack - 但我 100% 确定这是你的问题。
