AWS CDK：找不到模块“打字稿”答案

【问题标题】：AWS CDK: Cannot find module 'typescript'AWS CDK：找不到模块“打字稿”
【发布时间】：2021-08-10 02:59:56
【问题描述】：

长话短说，我有一个使用了将近一年的单一存储库。我有一个硬盘驱动器故障，不得不重新安装我的操作系统。现在，当我尝试对 CDK 执行任何操作时，每次都会收到此错误。

Cannot find module 'typescript'
Require stack:
- /home/jpsimkins/.npm/_npx/16449/lib/node_modules/ts-node/dist/index.js
- /home/jpsimkins/.npm/_npx/16449/lib/node_modules/ts-node/dist/repl.js
- /home/jpsimkins/.npm/_npx/16449/lib/node_modules/ts-node/dist/bin.js

这只影响cdk synth|diff|deploy 命令。我在运行测试时没有遇到任何问题，这让我在检查快照时更加困惑。

起初，我认为这与 PATH 有关，但我不确定为什么现在会成为问题。我确实使用了.husky，但后来用我自己的系统替换了它。我只提到这一点，以防万一这可能是值得了解的。

这可能是 node_module 解析的问题，因为我在这个项目和父级中有一个 node_modules 目录。我正在使用带有lerna 的单声道回购。这不是 lerna 问题，因为此问题仅在运行 cdk synth|diff|deploy 时发生。仅创建一个存储桶的简单测试将引发该错误。

我倾向于node_modules 决议。这没有在我的 tsconfig 所在的位置运行，因为所有其他脚本都正常工作。我不确定为什么只有 CDK 有这个问题。我已经用其他 4 个二进制文件（jest、prettier、eslint 和 tsc）进行了测试，它们运行得很好。问题仅在于cdk。

我将 Lerna 用于单声道存储库。

这是我的 devDependencies：

  "devDependencies": {
    "@aws-cdk/assert": "1.117.0",
    "@types/jest": "^26.0.10",
    "@types/node": "10.17.27",

    "typedoc": "^0.20.25",
    "typescript": "~3.9.7",
    "util": "^0.12.3"
  },

我在全局范围内安装了 Typescript，看看这是否有帮助（我通常对所有内容都使用本地安装），但没有。

我还通过运行tsc --showConfig 确认了 tsc 配置是我所期望的：

环境

 - **CDK CLI Version :**  1.117.0 (build 0047c98)
 - **Module Version :**  1.117.0
 - **Node.js Version :**  v14.17.4
 - **OS               :**  Linux Zeus 5.11.0-25-generic #27~20.04.1-Ubuntu SMP Tue Jul 13 17:41:23 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
 - **Language (Version):** Typescript (Version 3.9.10)

我什至尝试全局安装 typescript 和 cdk。这个问题仍然存在。

感谢任何见解..我花了一整天的时间试图解决这个问题，但没有运气..

【问题讨论】：

标签： typescript npm aws-cdk lerna

【解决方案1】：

我遇到了类似的问题，但我的构建无法正常工作。

但是，我将 ts-node 安装为全局似乎可以解决问题

npm install -g typescript
npm install -g ts-node
npm install -g aws-cdk

【讨论】：

我不想全局安装。虽然这会解决它，但这对我的方法来说并不理想。因为我希望所有东西都安装在本地。

【解决方案2】：

好的，我能够让它工作，但我不知道为什么在它使用当前系统工作一年多之后我必须这样做。我什至有其他开发人员毫无问题地使用它。很奇怪。

为了让它工作，我必须做一个简单的改变。

我将cdk.json修改为：

{
  "app": "../../../node_modules/.bin/ts-node --prefer-ts-exts src/index.ts",
  "context": {
    "@aws-cdk/core:enableStackNameDuplicates": "true",
    "aws-cdk:enableDiffNoFail": "true"
  }
}

现在我可以让cdk 命令工作了。

这可能是因为我没有在全球范围内安装任何东西。我要求在本地安装所有软件包，因为如果您只指定位置，二进制文件也可以这样做。我认为这在我最初在全球范围内安装之前是有效的，并且它们可能是它能够像现在这样工作的原因。为什么它适用于其他开发人员，我不确定因为他们没有在全球范围内安装（或者他们这么说）。

我的 boostrap 命令的一部分是删除所有node_modules 目录。问题是它只使用包node_modules 目录而不是Lerna 应该使用的父目录。无论如何，通过指定路径../../../node_modules/.bin/ts-node，我确信它现在可以使用正确的node_modules（父级）。
