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

问题描述

我在Angular5项目中有此import语句:

I have this import statement in an Angular5 project:

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

这解析为我文件系统上的该路径:

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，出现此错误:

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

我相信是因为我正在使用npm link链接'sce-plugins'项目进行本地开发.

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

在这里，我发现在Angular5项目中使用npm link存在一些问题:

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

有人知道如何解决吗?

更新:

它似乎与npm link本身或符号链接无关.如果仅将本地目录复制到node_modules/sce-plugins，则会收到同样的错误. 还，如果我npm install sce-plugins插入到node_modules中，那么我 not 不会收到错误.很奇怪，似乎与angular-cli有关，而不是与NPM有关.

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

因此，在再次阅读此Github问题之后: 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中进行了更改:

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

现在，考虑到preserveSymlinks标志和我的tsconfig.app.json文件中的include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.尽管我发现如果删除了"include"字段，则可能根本不需要"include"字段.

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.
