Cannot find name 'Config'

I am new to Typescript and sorry if this is a stupid question.

"npm install" runs successfully and generates the Config.d.ts file in config directory.
tsconfig.json has the config directory as one of the typeRoots:

"typeRoots"                       : [
      "config",
      "node_modules/@types"
 ]

And excludes the node_modules directory:

"exclude"        : [
    "node_modules",
    "**/*Test.ts"
 ]

When "tsc" runs it errors out with:

node_modules/node-config-ts/index.d.ts:4:30 - error TS2304: Cannot find name 'Config'

Thanks

having the same problem

@Cuneytt Sorry for the late response. Is your project on github somewhere? Also can u confirm the version of the library you are using?

Cuneytt commented

Thank you for the reply @tusharmath. Solved it for now using process.env directly and plan to get to it later. In the meantime, maybe @rburgst will be able to provide details he is running into.

@Cuneytt I also tried your tsc config and got this error —

yarn run v1.7.0
$ /Users/tushar/Documents/Projects/mobile/node_modules/.bin/tsc
error TS2688: Cannot find type definition file for 'deployment'.


error TS2688: Cannot find type definition file for 'env'.


error TS2688: Cannot find type definition file for 'user'.


error Command failed with exit code 2.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

I was able to solve the problem by removing typeRoots config from tsconfig.json.

@tusharmath Thanks, Will you please post the entire tsconfig.json you used to cross check with mine

Thank you very much @tusharmath

In case anyone hits this issue, it can also be caused by tsconfig.json including a "includes" section. If "includes" is not commented out (the default), it's necessary to add ./config to "includes" or tsc won't find the declaration for the Config interface.

e.g

"exclude": ["node_modules", "**/*.spec.ts", "extra_src"],
"include": ["./src/**/*", "./config/**/*"]

I try import { AuthenticationService } from '../authentication.service';
after compiling it give this ERROR in src/app/login/login.component.ts(17,19): error TS2304: Cannot find name 'AuthenticationService'.

This is my tsconfig.json
{
"compileOnSave": false,
"compilerOptions": {
"baseUrl": "./",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"downlevelIteration": true,
"experimentalDecorators": true,
"module": "esnext",
"moduleResolution": "node",
"importHelpers": true,
"target": "es2015",

"typeRoots": [
  "config",
  "node_modules/@types"
],

"lib": [
  "es2018",
  "dom"
]

},

"angularCompilerOptions": {
"fullTemplateTypeCheck": true,
"strictInjectionParameters": true
}
}
it is different than any of the above ones. Can someone help me understand what is happening here

My apologies to all. I had myself under the perception that all here were here for the same reason and bug. cannot find name 'Config'

bgausden commented

@larka06 assuming tsconfig is in the same folder as node_modules (if not, what's the reason?), are you sure it's necessary to include a typeRoots entry?

I don't know that it's a contributing factor but as typeRoots is generally not needed in a TS project, simplifying your tsconfig by removing typeRoots might help with troubleshooting.

@larka06 I guess you could be having the same issue — #51 (comment)
