The module '@angular/core' is not found in the Visual Studio Code IDE

It seems like a straightforward code. However, I am encountering the error 

cannot find module '@angular/core'
.

course.component.ts

import {Component} from '@angular/core'


@Component({
    selector: 'courses'
})
export class CoursesComponent{

}

typings.json

 {
  "ambientDependencies": {
    "es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#6697d6f7dadbf5773cb40ecda35a76027e0783b2"

}

I understand that this question has been answered several times. Unfortunately, due to my lack of knowledge, I am still confused.

Thank you for your assistance.

Answer №1

I encountered an issue because the typescript module was not selected correctly in my project. I resolved it by choosing the same module value of "tsconfig.json File -> compilerOptions -> module: commonjs" in the visual studio project properties. https://i.stack.imgur.com/rVJyM.jpg

Answer №2

After initially downloading the quick start seed from a course on udemy.com, it became clear that the course was outdated and there were some issues with the setup. I had to reach out to the instructor to address these issues.

Subsequently, I decided to re-download the quick start files from the official Angular website. Upon doing so, I noticed that the file structure was vastly different from the original one I had. For example, there was now an e2e folder and a tslint.json file present. The package.json file was located in the root folder, while the tsconfig.json file was found in the src folder.

With all these changes made, the project is now up and running smoothly. A big thank you to everyone who provided guidance along the way.

Answer №3

Your project's dependencies appear to be using outdated package naming conventions before the RC versions.

To resolve this issue, you can follow the instructions provided here. Essentially, you need to include @angular/core (along with other dependencies) in your package.json file.

For reference, here is an example of a package.json configuration:

{
    "name": "angular2-quickstart",
    "version": "1.0.0",
    "scripts": {
        "start": "concurrent \"npm run tsc:w\" \"npm run lite\" ",
        "tsc": "tsc",
        "tsc:w": "tsc -w",
        "lite": "lite-server",
        "typings": "typings",
        "postinstall": "typings install"
    },
    "license": "ISC",
    ...
}

You can also refer to the Angular QuickStart package.json for a more detailed example. Make sure to consult the documentation to customize based on your Angular version.

I hope this information proves helpful for your project customization needs.

In my experience with Ionic 3 projects, simply updating the typescript to the latest version resolved any issues for me.

npm i --save-dev typescript@latest

After that, you can run:

npm update

If you encounter problems with ionic serve, try running:

npm install

Answer №5

While facing a familiar error, the solution that worked for me might be different from what others have tried. After cloning a repository from GitHub, I encountered errors related to import statements. Suspecting missing files due to a .gitignore, I opted to execute the command npm install, which successfully added the necessary packages/files and eliminated the issue of "No projects support the 'build' target" when attempting to npm build.

Answer №6

When encountering this issue, it may stem from the absence of a specific file or folder. In order to resolve this matter, check for the presence of a folder labeled "node_modules" in the identical location as your package.json and tsconfig.json files. Proceed by navigating into node_modules -> @angular -> core.
