错误:加载PostCSS插件失败:找不到模块'postcss-import‘(Vue 2)

Question

我创建了我的第一个npm包。我在npmjs上发布了它，在项目中安装并运行该包后，遇到了缺少'postcss-import‘模块的错误。告诉我，问题可能出在哪里，在哪个文件中？我尝试了所有的方法，但没有works.Maybe这些文件有什么问题？

这是我的包的'package.json‘文件

  "_inBundle": false,
  "_integrity": "sha512-***",
  "_location": "/some_package",
  "_phantomChildren": {},

  },
  "bugs": {
    "url": "https://github.com/user/some_package/issues"
  },
  "homepage": "https://github.com/user/some_package#readme"
}

这是我的包的'.postcssrc.js‘文件

module.exports = {
  "plugins": {
    "postcss-import": {},
    "postcss-url": {},
    // to edit target browsers: use "browserslist" field in package.json
    "autoprefixer": {}
  }
}

您可以尝试：

npm install --save-dev postcss-import
