在运行时无法找到安装在本地路径上的package.json模块

Question

我的package.json中有两个包具有本地路径：

"graphql-subscriptions": "../graphql-subscriptions",
"subscriptions-transport-ws": "../subscriptions-transport-ws"

在npm install之后，它们将正确地安装在node_modules下。然而，当我运行我的node.js应用程序时，它会给出以下运行时错误：

module.js:529
    throw err;
    ^

Error: Cannot find module 'subscriptions-transport-ws'
    at Function.Module._resolveFilename (module.js:527:15)
    at Function.Module._load (module.js:476:23)
    at Module.require (module.js:568:17)
    at require (internal/module.js:11:18)
    at Object.<anonymous> (/Users/nbhati/projects/graphql-bookstore-server/src/app.factory.js:6:1)
    at Module._compile (module.js:624:30)
    at loader (/Users/nbhati/projects/graphql-bookstore-server/node_modules/babel-register/lib/node.js:144:5)
    at Object.require.extensions.(anonymous function) [as .js] (/Users/nbhati/projects/graphql-bookstore-server/node_modules/babel-register/lib/node.js:154:7)
    at Module.load (module.js:545:32)
    at tryModuleLoad (module.js:508:12)

我遗漏了什么？

Answer 1

谜团解开了。这些包是用TypeScript编写的。我必须编译它们才能被导入。
