报错提示如下:

调试了一下grpc模块,发现是调试模式下,node运行时的版本不对:
运行时的node版本是 11.10.1 版本,对应的 modules 版本是 67,所以当前版本下,和grpc版本对应的模块就是:node-v67-darwin-x64-unknown。
但我本地实际的版本是 14.13.0 版本,对应的 grpc 模块是 node-v83-darwin-x64-unknown,所以报错找不到:
究其原因,是vscode本身是一个js应用,使用的 electron 框架开发的桌面应用,里边内置的nodejs版本当前是 11.10.1 版本,且无法被改变:
解决办法,是在vscode的调试配置 .vscode/launch.json
文件里,用配置项runtimeVersion
配置指定的node版:
{ "version": "0.2.0", "configurations": [ { "type": "node", "runtimeVersion": "14.13.0", "request": "launch", "name": "native_server", "console": "integratedTerminal", "cwd": "${workspaceFolder}/projects/native_server", "runtimeArgs": ["-r", "ts-node/register/transpile-only"], "args": ["./server/bootstrap.ts"] } ] }
