json-typescript-mapper\libs\utils.ts is not part of the compilation output

[huskercane]

Hello,

I see following trying to build angular 5 application. This used to work with angular 4.

C:\Work\assurant\XXXManagementApp [angular-5 ≡ +0 ~1 -0 !]> npm start

XXXManagementApp@1.0.0 start C:\Work\assurant\XXXManagementApp
ng serve --proxy-config ./proxy.conf.js

I found this link that could explain
angular/angular-cli#8284

so I tried adding include to tsconfig.json but that did not solve it

[owennewo]

@huskercane - I got the same error (also using angular 5) and have resolved it. You are onto the right track with the include.
Here is my working tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ]
  },
  "include": [
    "src/**/*",
    "node_modules/json-typescript-mapper/libs/utils.ts"
  ]
}

So I've basically just add the include section. You need to be careful not to put it at the wrong level.

Reading around the issue, the above solution is a workaround. The json-typescript-mapper should not be shipping the utils.ts file to npm, the utils.js and utils.d.ts is sufficient. Another workaround is therefore to delete node_modules/json-typescript-mapper/libs/utils.ts - however I expect the file may come back on a npm clean or update.

[huskercane]

@owennewo your suggestion does solve the problem. This is proper work around thank you.

[Sir-J]

It's not helped me

[BBaysinger]

I tried @owennewo's solution, but got:

error TS18003: No inputs were found in config file 'tsconfig.json'. Specified 'include' paths were '["src/**/*","node_modules/json-typescript-mapper/libs/utils.ts"]' and 'exclude' paths were '["../dist/out-tsc"]'.

[BBaysinger]

Ok, I fixed that by adding ../ to both paths.

I'm getting the same error while running ng-test, even though I have added in tsconfig file.

{
"compileOnSave": false,
"compilerOptions": {
"module": "commonjs",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es5",
"typeRoots": [
"node_modules/@types"
],
"lib": [
"es2017",
"dom"
]
},
"exclude": [
"node_modules"
],
"include": [
"src/**/*",
"node_modules/json-typescript-mapper/libs/utils.ts"
]
}

I don't have any issue while running the application but it fails while I run the test cases.
Typescript version Used: "typescript": "~2.5.3"

RROR in ./node_modules/json-typescript-mapper/libs/utils.ts
Module build failed: Error: ..\node_modules\json-typescript-mapper\libs\utils.ts is missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
The missing file seems to be part of a third party library. TS files in published libraries are often a sign of a badly packaged library. Please open an issue in the library repository to alert its author and ask them to package the library using the Angular Package Format (https://goo.gl/jB3GVv).

I also added the "node_modules/json-typescript-mapper/libs/utils.ts" in 'tsconfig.spec.json but still facing the same issue.

[Rajashreegr]

The above error was actually my issue. I solved it by correcting the utils.ts path in tsconfig.spec.json file.
"../node_modules/json-typescript-mapper/libs/utils.ts" (I missed ../ before).

[DiegoVenancioVieira]

I still getting this problem, please somebody help:
