Question

我目前正在使用docker并尝试使用docker-compose来运行我的应用程序：

Node-Backend： hapi
JS-Frontend：棱角分明
MongoDB 数据库

mongodb与docker结合使用。我在OSX计算机上开发并使用 node-sass 作为前端部分。在编写时出现错误：

server_1  |     Child extract-text-webpack-plugin:
server_1  |       + 1 hidden modules
server_1  |     
server_1  |     ERROR in Missing binding /app/node_modules/node-sass/vendor/linux-x64-48/binding.node
server_1  |     Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 6.x
server_1  |     
server_1  |     Found bindings for the following environments:
server_1  |       - OS X 64-bit with Node.js 6.x
server_1  |     
server_1  |     This usually happens because your environment has changed since running `npm install`.
server_1  |     Run `npm rebuild node-sass` to build the binding for your current environment.

node-sass 模块似乎需要linux绑定，但只是在容器内部有osx绑定。所以问题是：有没有一种聪明的方法来解决这个问题，即使开发过程仍然很舒服？

到目前为止，我还没有Dockerfile。但我的docker-compose.yml看起来像是：

version: '2'
services:
  server:
    image: node:6
    command: 'npm start'
    working_dir: '/app'
    volumes:
      - ./:/app
    depends_on:
      - mongo
    ports:
      - '1337:1337'
    environment:
      - NODE_ENV=prod
    links:
      - mongo:mongodb
  mongo:
    image: mongo:latest
    ports:
      - '127.0.0.1:27017:27017'
    volumes:
      - ./data/:/data/db

package.json：

编辑：我的本地目录./被挂载到容器，因此我的OSX绑定模块也被挂载。是否有一种聪明的方法可以在容器内部执行新的npm i，而不会对开发过程有任何更大的限制？

Answer 1

您需要在容器内运行npm rebuild node-sass。您正在安装为OSX编译的二进制文件并尝试在Linux上运行。

Answer 2

这可能是旧闻，但万一有其他人遇到这个......

在容器内运行npm install（为容器运行的环境构建绑定）

然后将绑定从node_modules/node-sass/vendor/复制到开发环境中。

我在Mac上为dev env执行此操作，但是在节点上执行此操作：alpine for running container。

Answer 3

您应该编辑您的npm图像，在其中创建自己的运行public void ConfirmBtn_Click(object sender, EventArgs e) { string connString1 = "FirstConnectionSTring"; string connString2 = "SecondConnectionSTring"; ExecuteNonQuery(connString1); ExecuteNonQuery(connString2); } public void ExecuteNonQuery(string connString) { using (SqlConnection connection = new SqlConnection(connString)) { connection.Open(); SqlCommand cmd = new SqlCommand("DELETE FROM TABLE1 WHERE ID=@ID", connection); cmd.Parameters.AddWithValue("@ID", textbox1.Text); cmd.ExecuteNonQuery(); } }，而不仅仅是npm install。因此容器内的npm包将与容器OS兼容。您可以检查https://github.com/titouanfreville/SupJirallo（我没有使用node-sass，但它有一个带有npm install的节点映像）。

使用带有docker-compose
