VSCode cannot find module '@angular/core' or any other modules
AngularVisual Studio-CodeAngular Problem Overview
My project was generated with Angular CLI version 1.2.6.
I can compile the project and it works fine, but I always get error in VSCode telling me:
> cannot find module '@angular/core' > cannot find module '@angular/router' > cannot find module .....
I have attached content of my tsconfig.json
file
this has been really frustrating for me, spending 2 hours to figure out what is wrong,
I have also uninstalled and reinstalled the VSCode
it doesn't work.
Here is my environment specification:

Angular Solutions
Solution 1 - Angular
I was facing this issue only while importing my own created components/services For those of you like me, for whom the accepted solution did not work, can try this:
Add
"baseUrl": "src"
in your tsconfig.json
. The reason is that visual code IDE is unable to resolve the base url so is unable to resolve path to imported components and gives error/warning.
Whereas angular compiler takes src
as baseurl by default so it is able to compile.
NOTE:
You need to restart VS Code IDE to make this change come into effect.
EDIT:
As mentioned in one of the comments, in some cases changing workspace version might also work. More details here: https://github.com/Microsoft/vscode/issues/34681#issuecomment-331306869
Solution 2 - Angular
Most likely missing node_modules
package in the angular project, run:
npm install
inside the angular project folder.
Solution 3 - Angular
Visual Code restart is needed if any update or install or clear cache
Solution 4 - Angular
the fix for me was to run
npm install
and then unload,then reload the project in visual studio.
Solution 5 - Angular
I was facing this issue in my angular 5
application today. And the fix which helped me, was simple. I added "moduleResolution": "node"
to the compilerOptions
in the tsconfig.json
file. My complete tsconfig.json
file content is below.
{
"compileOnSave": false,
"compilerOptions": {
"baseUrl": "./",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es5",
"typeRoots": [
"node_modules/@types"
],
"lib": [
"es2017",
"dom"
]
}
}
The moduleResolution
specify module resolution strategy. The value of this settings can be node
or classic
. You may read more about this here.
Solution 6 - Angular
Delete Node Modules folder from project folder.Run below command
npm cache clean --force
npm install
It should work.
Solution 7 - Angular
I was facing the same issue , there could be two reasons for this-
- Your
src
base folder might not been declared, to resolve this go totsconfig.json
and add thebaseUrl
as "src
"
{
"compileOnSave": false,
"compilerOptions": {
"baseUrl": "src",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"downlevelIteration": true,
"experimentalDecorators": true,
"module": "esnext",
"moduleResolution": "node",
"importHelpers": true,
"target": "es2015",
"lib": [
"es2018",
"dom"
]
},
"angularCompilerOptions": {
"fullTemplateTypeCheck": true,
"strictInjectionParameters": true
}
}
- you might have problem in npm , To resolve this , open your command window and run-
npm install
Solution 8 - Angular
Try using:
npm audit fix --force
and then:
npm install --save @ng-bootstrap/ng-bootstrap
instead of saving @ng-bootstrap/ng-bootstrap
globally.
Solution 9 - Angular
I had the same problem. I resolved it by clearing npm cache which is at "C:\Users\Administrator\AppData\Roaming\npm-cache"
Or you can simply run:
npm cache clean --force
and then close vscode, and then open your folder again.
Solution 10 - Angular
In the VSCode status bar, it must be showing typescript version - like this
Clicking on that version number will show you this, different versions available.
If you are using the VSCode version then switching to Workspace version solves the problem if it is VScode issue rather than your tsconfig.json
(I am already using that one, so not highlighted)
Solution 11 - Angular
You need to install it manually.
$ npm i @angular/core -s
Solution 12 - Angular
I tried a lot of stuff the guys informed here, without success. After, I just realized I was using the Deno Support for VSCode extension. I uninstalled it and a restart was required. After restart the problem was solved.
Solution 13 - Angular
I faced the same problem , As I'm trying to work on angular project in VS code.
The solution for which this issue resolved is .
- Delete the node_modules folder if you have one in your project folder
2.run the following command in terminal
npm install
-
Then Run npm audit fix
-
Then Run npm audit fix --force
now the issue will be resolved.
Solution 14 - Angular
I uninstalled all extension I had already installed, and it turns out JavaScript and TypeScript IntelliSense extension from below address caused the issue. https://marketplace.visualstudio.com/items?itemName=sourcegraph.javascript-typescript
the point here is when you visit the website you see there is a yellow label, telling you it is in preview release, but when you browse in vs extensions, you don't see that label.
Solution 15 - Angular
this extension https://marketplace.visualstudio.com/items?itemName=sourcegraph.javascript-typescript was causing me the error in visual code, I uninstalled it and it works for me
Solution 16 - Angular
In my case it was a mispelling of the import line. Check that you have spelt the @angular/core
part properly if typing it out manually.
import { Component } from '@angular/core';
Solution 17 - Angular
The fix for me was to import the entire project. For those who have this problem in 2019 please check if you have imported the entire project not a part of the project.
Solution 18 - Angular
If you did what I (foolishly) did... Which was drag and drop a component folder into my project then you'll probably be able to solve it by doing what I did to fix it.
Explanation: Basically, by some means Angualar CLI must tell InteliJ what @angular
means. If you just plop the file in your project without using the Angular CLI i.e. ng g componentName --module=app.module
then Angular CLI doesn't know to update this reference so IntelliJ has no idea what it is.
Approach: Trigger the Angular CLI to update references of @angular
. I currently know only one way to do this...
Implementation: Add a new component at the same level as the component your having issues with. ng g tempComponent --module=app.module
This should force the Angular CLI to run and update these references in the project.
Now just delete the tempComponent you just created and don't forget to remove any reference to it in app.module.
Hope this helps someone else out.
Solution 19 - Angular
I had the same issue, was strange because project compiled and ran without errors. I updated npm and then reinstalled the packages
npm update
npm install
then vs code stop saying that.
Solution 20 - Angular
Most likely npm package is missing. And sometimes npm install does not fix the problem.
I have faced the same and I have solved this issue by deleting the node_modules
folder and then npm install
Solution 21 - Angular
I've encountered this problem and fixed it by following commands.
npm cache clean --force
npm i @angular/core -s
And then don't forget to restart your VS code. It must be fixed.
Solution 22 - Angular
Occurs when cloning or opening existing projects in Visual Studio Code.
In the integrated terminal run the command npm install
Solution 23 - Angular
Executing the following two commands solves the problem for me:
npm install -g @angular/cli
ng update --all --force
Solution 24 - Angular
for Visual Studio -->
Seems like you don't have `node_modules` directory in your project folder.
Execute this command where `package.json` file is located:
npm install
Solution 25 - Angular
Try this, it worked for me:
npm i --save @angular/platform-server
Then reopen VS code
Solution 26 - Angular
This worked for me.
npm install --save-dev @angular-devkit/build-angular
Solution 27 - Angular
In my case, when i upgrade vs project to angular 10, I had this errors.
Angular cli creates tsconfig.json
, tsconfig.base.json
and tsconfig.app.json
when i delete tsconfig.json and rename tsconfig.base.json to tsconfig.ts all things will Ok.
you must also change extends inside tsconfig.app.json to tsconfig.json
Solution 28 - Angular
I had same problems with Sublime Text.
I came up with following solution: I just edited
> tsconfig.json
in the root of Angular workspace to include my freshly created application.
{
"files": [],
"references": [
{
"path": "./projects/client/tsconfig.app.json"
},
{
"path": "./projects/client/tsconfig.spec.json"
},
{
"path": "./projects/vehicle-market/tsconfig.app.json"
},
{
"path": "./projects/vehicle-market/tsconfig.spec.json"
},
{
"path": "./projects/mobile-de-lib/tsconfig.lib.json"
},
{
"path": "./projects/mobile-de-lib/tsconfig.spec.json"
}
]
}
Solution 29 - Angular
All you need to do is that you have to include nodes_modules
folder in your project. You might face this problem when you clone any project from github through git command line.
Solution 30 - Angular
Do run
npm install
it will work most of the cases
Solution 31 - Angular
I solved this problem as follow:
- Open Visual studio code with your project.
- Terminal -> New Terminal.
- Write
npm install
.
Solution 32 - Angular
From my point of view the CLI you are using and the libraries are mismatched. The ionic CLI version 1 cannot build libraries for ionic CLI version 4. The best solution is to try upgrade your CLI version. You can otherwise use nvm which allows you to run multiple node versions on the same O.S. This can help you use different ionic CLI versions across different projects depending on the requirements.
Check out nvm @: Their official windows repo. There is also a MAC and Linux version.
Solution 33 - Angular
If we get this type of error just use the command:
npm i @anglar/core,
npm i @angular/common,
npm i @angular/http,
npm i @angular/router
After installing this also showing error just remove few words then again add that word its working.
