Error: Cannot find module/ApolloServer/protobufjs/minimal when starting ApolloServer for Express in production

Question

我正在使用 TypeScript 创建一个 ApolloExpressServer。当运行在开发模式下使用

时代码运行良好

ts-node -r tsconfig-paths/register ./src --env=development

但是在我使用 tsc --build tsconfig.prod.json 构建项目后它构建成功但是当我尝试使用 node -r module-alias/register ./dist

启动服务器时失败

输出错误

Error: Cannot find module '/dist/ApolloServer/protobufjs/minimal'
Require stack:
- /node_modules/apollo-engine-reporting-protobuf/dist/protobuf.js
- /node_modules/apollo-engine-reporting-protobuf/dist/index.js
- /node_modules/apollo-engine-reporting/dist/agent.js
- /node_modules/apollo-server-core/dist/ApolloServer.js
- /node_modules/apollo-server-core/dist/index.js
- /node_modules/apollo-server-express/dist/index.js

我目前正在使用

"apollo-server-express": "^2.17.0"
"typescript": "^3.9.3"

我发现了问题。这是因为我的 package.json 中的 moduleAlias 而发生的。我创建了一个模块别名，如

{
    "name": "apollo-express-server",
    "version": "0.0.0",
        "_moduleAliases": {
        "@middlewares": "dist/middlewares",
        "@validators": "dist/validators",
        "@models": "dist/models",
        "@shared": "dist/shared",
        "@config": "dist/config",
        "@server": "dist/Server",
        "@apollo": "dist/ApolloServer"
    },
}

删除行 "@apollo": "dist/ApolloServer" 解决了问题。显然它正在覆盖 /node_modules/@apollo/* 并将其指向 dist/ApolloServer
