在serverless中使用prisma

众所周知为了冷启动速度一般要将代码打包到一个js文件。

当在项目中使用了 prisma 打包完后上传到serverless平台，一般会遇到第一个问题：

 Error: 
 Invalid `prisma.companie.findMany()` invocation:
 
 
   Query engine binary for current platform "debian-openssl-1.1.x" could not be found.
 This probably happens, because you built Prisma Client on a different platform.
 (Prisma Client looked in "/home/ubuntu/nacho/server/node_modules/@prisma/client/runtime/query-engine-debian-openssl-1.1.x")
 
 
 To solve this problem, add the platform "debian-openssl-1.1.x" to the "generator" block in the "schema.prisma" file:
 generator client {
   provider      = "prisma-client-js"
   binaryTargets = ["native"]
 }
 
 Then run "prisma generate" for your changes to take effect.

     at PrismaClientFetcher.request (/home/ubuntu/nacho/server/node_modules/@prisma/client/runtime/index.js:79361:15)
     at process._tickCallback (internal/process/next_tick.js:68:7) clientVersion: '2.12.1' }

经过搜索后得知 prisma/issues/4769 ，prisma 在不同平台是依赖不同二进制文件的。

那么现在修改 prisma 配置重新生成代码再 编译打包上传运行 依旧会出现找不到该文件的问题。

例如：

PrismaClientInitializationError: Prisma Client could not locate the Query Engine for runtime "debian-openssl-1.1.x".

This is likely caused by a bundler that has not copied "libquery_engine-debian-openssl-1.1.x.so.node" next to the resulting bundle.
Ensure that "libquery_engine-debian-openssl-1.1.x.so.node" has been copied next to the bundle or in "node_modules/.pnpm/@[email protected][email protected]/node_modules/.prisma/client".

We would appreciate if you could take the time to share some information with us.
Please help us by answering a few questions: https://pris.ly/engine-not-found-bundler-investigation

The following locations have been searched:
  /code/node_modules/.pnpm/@[email protected][email protected]/node_modules/.prisma/client
  /
  D:\code\node_modules\.pnpm\@[email protected][email protected]\node_modules\@prisma\client
  /.prisma/client
  /tmp/prisma-engines
    at dl (/code/fc.js:170:805)
    at async Object.loadLibrary (/code/fc.js:217:9816)
    at async zt.loadEngine (/code/fc.js:219:448)
    at async zt.instantiateLibrary (/code/fc.js:218:10356) {
  clientVersion: '5.7.1',
  errorCode: undefined
}

现在需要从本地找到该文件 libquery_engine-debian-openssl-1.1.x.so.node​

然后和代码一起上传，注意路径要和你编译后的代码中所依赖的一致
