Fout TS2307: kan module ‘@ hoek / kern’ niet vinden

Dus ik krijg de volgende foutmelding toen ik mijn aanvraag opnieuw probeerde te bouwen:

ERROR in ../../../node_modules/@angular/cdk/a11y/typings/aria-describer/aria-describer.d.ts(8,42): error TS2307: Cannot find module '@angular/core

Deze fout is opgetreden terwijl ik mijn hoekige toepassing ontwikkelde. Ik kreeg blijkbaar dit terwijl ik programmeerden, maar ik heb het niet opgemerkt omdat de applicatie gewoon net gewoon bleef het verzamelen wanneer ik enkele veranderingen heb gemaakt. Deze fout begon alleen maar te voorkomen dat ik de applicatie vanmorgen bouwde. Weet iemand wat hier gebeurt?

Volledige fout:

Dit probleem werd blijkbaar veroorzaakt door de CDK en materiaalmodules van hoekig. Ik weet niet precies hoe het is gebeurd, maar ik heb het opgelost.

Ik heb het opgelost door een antwoord te volgen in dit github-probleem: https://github.com/ hoekig/material2/issues/8306

Oplossing

Om dit probleem op te lossen, moet u de volgende opdrachten uitvoeren:

npm install --save @angular/material @angular/cdk
rm -rf node_modules
npm install

Ik zie dat sommige oplossingen radicaal zijn, dat zou ik in de eerste plaats niet proberen. Mijn oplossing was niet radicaal en deed zijn werk.

Ik had het probleem ook, ik deed een simpele
npm update
Dit kwam eruit:

$> npm update

En dat het probleem opgelost.

Om dit probleem moet je om de update te bevestigen aan Angular CLI versie, als @angular cdk 6.0vereist @angular core 6.0 version(bijgewerkte versie). Probeer bijgewerkte versie gebruiken voor zowel CLI en materiaal / CDK

Voer de volgende stappen: –

npm uninstall -g @angular/cli
npm cache verify

als npmversie ligt op minder dan 5 dan gebruik maken van npm cache clean

npm install -g @angular/[email protected]

maak vervolgens nieuwe angluar/cliproject daarna installeren @angular/materialen @angular/cdk.

Ik hoop dat dit zal uw probleem op te lossen.

Voor mij is het probleem opgelost als ik ervoor zorg dat de versies @angular/material, @angular/ckden @angular/animationszijn compatibel met de versie @angular/core. Bewerk gewoon package.json.

In mijn geval:

"@angular/core": "^7.2.15",
"@angular/animations": "^7.2.15",
"@angular/material": "^7.3.3",
"@angular/cdk": "^7.3.7",
