缺少 *.ts 文件(由于 `npm link` ?) [英] Missing *.ts files (due to `npm link` ?)

问题描述

我在 Angular5 项目中有这个导入语句:

I have this import statement in an Angular5 project:

import {plugins, SCECodeGenType} from 'sce-plugins/code-generation';

这将解析为我文件系统上的此路径:

this resolves to this path on my filesystem:

/Users/.../suman-chrome-extension/node_modules/sce-plugins/code-generation/index.d.ts

使用 ng build -w 构建应用程序时，我收到此错误:

When building the app with ng build -w, I get this error:

ERROR in ../sce-plugins/code-generation/index.ts Module build failed: Error: /Users/alexamil/WebstormProjects/oresoftware/sumanjs/sce-plugins/code-generation/index.ts is missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
    at AngularCompilerPlugin.getCompiledFile (/Users/alexamil/WebstormProjects/oresoftware/sumanjs/suman-chrome-extension/node_modules/@ngtools/webpack/src/angular_compiler_plugin.js:662:23)
    at plugin.done.then (/Users/alexamil/WebstormProjects/oresoftware/sumanjs/suman-chrome-extension/node_modules/@ngtools/webpack/src/loader.js:467:39)
    at <anonymous>  @ ./src/app/shared/services/lang.service.ts 14:24-62  @ ./src/app/app.module.ts  @ ./src/main.ts  @ multi ./src/main.ts

我相信这是因为我使用 npm link 来链接 'sce-plugins' 项目以进行本地开发.

I believe it's because I am using npm link to link the 'sce-plugins' project for local development.

我在这里看到在 Angular5 项目中使用 npm link 的一些问题:

I see some issues with using npm link with Angular5 projects here:

https://github.com/angular/angular-cli/issues/3875

https://github.com/angular/angular-cli/issues/8677

https://github.com/angular/angular-cli/issues/9376

有人知道怎么解决吗?

更新:

它似乎与 npm link 本身或符号链接无关.如果我只是将本地目录复制到 node_modules/sce-plugins，我会得到同样该死的错误.然而，如果我 npm install sce-plugins 到 node_modules 中，那么我不会得到错误.很奇怪，好像和angular-cli有关，而不是NPM.

It does not seem to have do with npm link perse, or symlinks. If I simply copy the local directory over to node_modules/sce-plugins, I get the same damn error. Yet, if I npm install sce-plugins into node_modules then I do not get the error. Very strange, seems like it has to do with angular-cli, not NPM.

推荐答案

所以在再次阅读这个 Github 问题后:https://github.com/angular/angular-cli/issues/8284

So after reading this Github issue again: https://github.com/angular/angular-cli/issues/8284

我在 .angular-cli.json 中做了这个改动:

I made this change in .angular-cli.json:

  "defaults": {
    "build": {
      "preserveSymlinks": true //   <<<< add this
    },
    "styleExt": "scss",
    "component": {
    }
  }

现在，鉴于 preserveSymlinks 标志和我的 tsconfig.app.json 文件中的包含字段:

and now, given that preserveSymlinks flag and the include field in my tsconfig.app.json file:

 "include":[
    "./**/*.ts",
    "../node_modules/sce-plugins/**/*.ts"
  ],

我现在可以将 'sce-plugins' 符号链接到我的主项目中，而不是手动复制文件.您可能根本不需要 "include" 字段，尽管我发现如果删除 "include" 字段，它将不起作用.

I can now symlink 'sce-plugins' into my main project, instead of manually copying the files. It's possible that you won't need the "include" field at all, although I found that if I removed the "include" field, that it wouldn't work.
