VS 2015 community edition (at home), npm 3.10, Angular 2 Im trying to pull get Angular2 setup within an ASP.Net MVC 5 app. The template I started with used an older version of Angular, so I updated the package references.
When I build, the first error in the list is:
Build:Cannot find type definition file for 'node'
There are dozens of other errors after that but Im assuming most are due to this first issue.
Here is the package.json and typings.json
package.json
{
"version": "1.0.0",
"name": "aspnet",
"private": true,
"scripts": {
"postinstall": "typings install",
"typings": "typings"
},
"dependencies": {
"@angular/common": "~4.0.0",
"@angular/compiler": "~4.0.0",
"@angular/core": "~4.0.0",
"@angular/forms": "~4.0.0",
"@angular/http": "~4.0.0",
"@angular/platform-browser": "~4.0.0",
"@angular/platform-browser-dynamic": "~4.0.0",
"@angular/router": "~4.0.0",
"angular-in-memory-web-api": "~0.3.0",
"systemjs": "0.19.40",
"core-js": "^2.4.1",
"rxjs": "5.0.1",
"zone.js": "^0.8.4",
"bootstrap": "^3.3.7"
},
"devDependencies": {
"@types/core-js": "^0.9.41",
"gulp": "^3.9.1",
"gulp-clean": "^0.3.2",
"gulp-concat": "^2.6.1",
"gulp-tsc": "^1.3.1",
"gulp-typescript": "^3.1.6",
"path": "^0.12.7",
"typescript": "~2.1.0",
"typings": "~2.1.1"
}
}
typings.json
{
"globalDependencies": {
"core-js": "registry:dt/core-js#0.0.0+20160725163759",
"jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
"node": "registry:dt/node#6.0.0+20160909174046"
}
}
If I try to update just the typings, I get these messages
*typings WARN deprecated 11/21/2016: "registry:dt/node#6.0.0+20160909174046" is deprecated (updated, replaced or removed)
typings WARN deprecated 9/14/2016: "registry:dt/core-js#0.0.0+20160725163759" is deprecated (updated, replaced or removed)
typings WARN deprecated 10/25/2016: "registry:dt/jasmine#2.2.0+20160621224255" is deprecated (updated, replaced or removed)*
[ update ]
cleaning out my node_modules folder, then running npm install again cleared things up. This seems to happen most often when I move a project folder to another location on my system.

Have you tried turning it off and on again?
(Try restarting or reloading VSCode)

In my case, I migrated my Angular app from v16 to v17 and encountered the following error:
Error: error TS2688: Cannot find type definition file for 'node'.
The file is in the program because:
Entry point of type library 'node' specified in compilerOptions
After trying various solutions, I finally found the root cause: the "types": ["node"]
entry in the tsconfig.app.json
file. Removing this entry resolved the issue."

I faced exact issue while trying to upgrade to Angular 17 which needs typescript >=5.2 & < 5.3.
To fix it you need to have:
In my case below snippet in tsconfig.json fixed it:
{
"compilerOptions": {
"types": [ "node" ],
"typeRoots": [ "./node_modules/@types", "../node_modules/@types", "../../node_modules/@types" ]
}
If you don't have a mono repo the first value inside typeRoots might be sufficient. Do note the leading dot signifying relative path.

in my case, the package has been deprecated,
when I
npm install
, the issue starts here, I've removed that package in package.json
and removed the node_modules folder, npm install
again, and restarted the app, it's worked for me

In my case, I had the problem because of the presence of the following in my tsconfig:
"typeRoots": ["node_modules/@type"]
Removing that line fixed the problem.

for rocketchat apps, this should fix the problem:
npm link @types/node

On my end, this was an issue with the TS server in VSCode. You can simply restart the server by:
Opening any TS file > CMD + SHIFT + P > TypeScript: Restart TS Server

The easiest way to go around this in vscode is.
create a .vscode directory, then inside it, create settings.json and put the below json and you are good to go.
{
"search.exclude": {
"**/node_modules": true
},
"files.watcherExclude": {
"**/.git/objects/**": true,
"**/.git/subtree-cache/**": true,
"**/node_modules/**": true,
"env-*": true
},
"files.exclude": {
"**/.git": true,
"**/.DS_Store": true,
"**/node_modules": true,
"env*": true
}
}

sometimes its just because some package(s) are missing. you can try running yarn install
or npm install
should resolve.

In my case, I solved my problem. Hopefully it helps some else later.
npm install @types/node --save-dev

I had several problems updating packages through visual studio. From now i always update or add packages with the powershell console.
Start PowerShell
and navigate to the folder where package.json
is located and then run npm install
Restart visual studio after the installation is done.
You can also try to delete your node_modules
folder then run npm install
Hope this will solve your problems.

If you're starting with a clean template the build in VS functionality should probably work!
Go to Dependencies
> npm
> Right Click > Restore Packages
Then try build again.
Install node https://nodejs.org/en/download/
Restart your agent service (VSTS Agent) if not using hosted agents
Add a build task to run npm install
Click the menu icon next to 'Working folder' to choose the location where your project.json file is located.
