Bien, actualicé Angular de 6 a 8. Pero sigo recibiendo errores.

Encontré en Internet una solución que ayudó a muchos usuarios. Pero en este caso no me ayudó.

Entonces mi archivo package.json se ve así:

 { "name": "vital10-frontend", "version": "0.55.0", "license": "Unlicensed", "scripts": { "ng": "ng", "start": "ng serve", "hmr": "ng serve --configuration hmr", "build": "ng build", "build:prod": "npm run sass:prod && npm run vit10prod", "build:acc": "npm run sass:prod && npm run vit10acc", "build:test": "npm run sass:prod && npm run vit10test", "build:dev": "npm run sass:prod && npm run vit10dev", "test": "ng test", "test:cover": "ng test --code-coverage", "lint": "ng lint", "e2e": "ng e2e", "local": "ng serve -c local", "analyze-bundle": "webpack-bundle-analyzer dist/stats.json", "postinstall": "node patch-webpack.js", "sass:watch": "sass --watch sass:src\\assets", "sass:prod": "sass --update -f --style compressed --sourcemap=none sass:src\\assets", "vit10dev": "ng build --prod -c vit10dev", "vit10test": "ng build --prod -c vit10test", "vit10acc": "ng build --prod -c vit10acc", "vit10prod": "ng build --prod -c production" }, "private": true, "dependencies": { "@angular/animations": "^8.1.2", "@angular/cdk": "^7.3.7", "@angular/common": "^8.1.2", "@angular/compiler": "^8.1.2", "@angular/core": "^8.1.2", "@angular/forms": "^8.1.2", "@angular/http": "^7.2.15", "@angular/platform-browser": "^8.1.2", "@angular/platform-browser-dynamic": "^8.1.2", "@angular/platform-server": "^8.1.2", "@angular/router": "^8.1.2", "@types/chart.js": "^2.7.54", "buffer": "^5.2.1", "chart.js": "^2.7.2", "core-js": "^2.5.7", "events": "^3.0.0", "fs": "0.0.1-security", "jasmine": "^3.1.0", "ng2-charts": "^1.6.0", "ng2-dragula": "^2.1.1", "ng2-pdf-viewer": "^5.0.1", "node-sass": "^4.11.0", "oidc-client": "^1.5.1", "path": "^0.12.7", "pdfjs-dist": "^2.0.489", "rxjs": "^6.5.2", "rxjs-compat": "^6.5.2", "stream": "0.0.2", "timers": "^0.1.1", "web-animations-js": "^2.3.1", "zone.js": "^0.9.1" }, "devDependencies": { "@angular-devkit/build-angular": "^0.801.2", "@angular/cli": "^8.1.2", "@angular/compiler-cli": "^8.1.2", "@angular/language-service": "^8.1.2", "@angularclass/hmr": "^2.1.3", "@compodoc/compodoc": "^1.1.10", "@types/jasmine": "^3.3.14", "@types/node": "^12.6.8", "chai": "^4.1.2", "codelyzer": "^5.1.0", "convert-csv-to-json": "0.0.13", "cucumber": "^4.2.1", "cucumber-html-reporter": "^5.0.0", "cucumber-junit": "^1.7.1", "express-static": "^1.2.5", "jasmine-core": "^3.4.0", "jasmine-reporters": "^2.3.1", "jasmine-spec-reporter": "^4.2.1", "karma": "^4.2.0", "karma-chrome-launcher": "^3.0.0", "karma-cli": "^2.0.0", "karma-coverage-istanbul-reporter": "^1.2.1", "karma-html-reporter": "^0.2.7", "karma-jasmine": "^2.0.1", "karma-jasmine-html-reporter": "^1.4.2", "karma-junit-reporter": "^1.2.0", "karma-teamcity-reporter": "^1.1.0", "moment": "^2.22.1", "prettier": "1.13.4", "protractor": "^5.4.2", "protractor-beautiful-reporter": "^1.2.1", "protractor-cucumber-framework": "^5.0.0", "puppeteer": "^1.14.0", "request": "^2.87.0", "request-promise-native": "^1.0.5", "ts-node": "^3.3.0", "tslint": "^5.18.0", "tslint-angular": "^1.1.2", "typescript": "3.4.5", "webpack-bundle-analyzer": "^3.3.2", "xlsx": "^0.12.13" }, "browser": { "fs": false, "path": false, "os": false, "crypto": false, "stream": false, "http": false, "tls": false, "zlib": false, "https": false, "net": false } }

Y mi archivo b tsconfig.json se ve así:

 { "compileOnSave": false, "compilerOptions": { "outDir": "./dist/out-tsc", "baseUrl": "src", "sourceMap": true, "declaration": false, "moduleResolution": "node", "emitDecoratorMetadata": true, "experimentalDecorators": true, "target": "es5", "typeRoots": [ "node_modules/@types" ], "lib": [ "es2016", "dom" ] }, "angularCompilerOptions": { "enableIvy": false } }

Pero sigo recibiendo estos errores:

 ERROR in ./node_modules/resolve/lib/async.js Module not found: Error: Can't resolve 'fs' in 'C:\Source\nien\vital10-frontend\node_modules\resolve\lib' ERROR in ./node_modules/resolve/lib/sync.js Module not found: Error: Can't resolve 'fs' in 'C:\Source\nien\vital10-frontend\node_modules\resolve\lib' ERROR in ./node_modules/resolve/lib/node-modules-paths.js Module not found: Error: Can't resolve 'fs' in 'C:\Source\nien\vital10-frontend\node_modules\resolve\lib' ERROR in ./node_modules/tslint/lib/utils.js Module not found: Error: Can't resolve 'fs' in 'C:\Source\nien\vital10-frontend\node_modules\tslint\lib'

Encontré una posible solución, que hay que poner alguna configuración en uno de los node_modules. Pero creo que no es una buena solución. Porque si elimina todas las importaciones y luego vuelve a instalar las importaciones, sus configuraciones desaparecerán.

Gracias

Bien, eliminé el

 "fs": "0.0.1-security",

Eliminé todos los paquetes (node_modules) e hice una instalación de npm.

Pero ahora me sale esto:
