hi，
i try to use node-odbc v2.3.6 as my node version is limited to v8.17.0, but i got some napi_bigint error when i run npm install, how can i fix this?

Unfortunately we have long since moved on from Node.js 8 and v2.3 of node-odbc. This commit added conditional compilation for BigInt support. Maybe you can use a github url dependency eg.

  "dependencies": {
    "odbc": "IBM/odbc#d9c630909f12b8a4c9bb1e9d82531ef6792cd08c",
  }

I haven't actually used this support or tested this, though. It's as much help as we can provide. Good luck!
