【中文标题】节点 Lambda:ts-node 的导入导致 TypeError【英文标题】:Node Lambda: Import of ts-node results in TypeError 【发布时间】:2017-02-20 11:44:40 【问题描述】:我是节点新手并编写服务器端代码,所以请多多包涵。
目前,我正在使用 Typescript 编写一个节点 lambda。为了在我的项目中使用它,我需要 typescript 模块作为依赖项,所以我将它们列在我的package.json
文件中,并且它们与npm install
一起安装。接下来我运行 npm test
并收到此错误日志。
LT-2012011001:example-data-sync amohnacs$ npm test

throw new TypeError(

TypeError: Unable to require `.d.ts` file.
This is usually the result of a faulty configuration or import. Make sure there is a `.js`, `.json` or another executable extension and loader (attached before `ts-node`) available alongside `/Users/amohnacs/Developer/git/example-data-sync/node_modules/any-promise/implementation.d.ts`.

它告诉我我的项目配置不正确,但按照它看起来的路径在ts-node
中出现了问题。我在项目配置中是否有遗漏或不正确的内容,或者我可能使用了不正确版本的 ts-node 或 Typescript。
提前谢谢你。
【问题讨论】:
【参考方案1】:在 package.json 的 nyc.exclude 部分添加 node_modules。
"nyc":
"exclude": [
"spec/**/*.spec.ts",
"typings",
"node_modules"
],
【讨论】:
【参考方案2】:对于我的情况,下面解决了这个问题,但不排除 .ts
文件:
ts-jest
,见说明here
然后,我在jest.config.js
中添加了
globals:
'ts-jest':
isolatedModules: true
,
,
根据this fix
