Node.js node_modules\grpc\src\node\extension_binary\node-v83-win32-x64-unknown\grpc_node.node

Question

I was doing a proof of concept on gRPC using node.js

Here is my package.json

{
  "name": "grpc-node-demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "dependencies": {
    "@grpc/proto-loader": "^0.1.0",
    "grpc": "^1.11.0",
    "lodash": "^4.6.1"
  }
}

After writing in proto file, client and server files. When I run the command node server.js I got the following error

PS C:\Learnings\node\grpc-nodejs-demo> node server.js
C:\Learnings\node\grpc-nodejs-demo\node_modules\grpc\src\grpc_extension.js:58
    throw e;
    ^

Error: Failed to load C:\Learnings\node\grpc-nodejs-demo\node_modules\grpc\src\node\extension_binary\node-v83-win32-x64-unknown\grpc_node.node. \\?\C:\Learnings\node\grpc-nodejs-demo\node_modules\grpc\src\node\extension_binary\node-v83-win32-x64-unknown\grpc_node.node is not a valid Win32 application.

Any thoughts??

Answer 1

After some research, I did the following steps to resolve the issue

• I was missing node-gyp - which is Node.js native addon build tool. It can be installed by

  npm install -g node-gyp

• Install Python

• Install Visual C++ Build Environment

• Clean up node-modules

• Then do in the folder npm install

The following link talks the above steps in detail: https://github.com/nodejs/node-gyp#on-windows
