I started upgrade from Angular 5 to Angular 10. Now upgraded till Angular 10 but When I'm running ng serve command then getting below error. I have already tried below two commands
'npm cache verify' then deleting node module folder then 'npm install'

Errors:

ERROR in ./node_modules/xlsx-style/dist/cpexcel.js Module not found: Error: Can't resolve './cptable' in 'D:\PD\service\angular\node_modules\xlsx-style\dist' ERROR in ./node_modules/xlsx-style/xlsx.js Module not found: Error: Can't resolve 'fs' in 'D:\PD\service\angular\node_modules\xlsx-style' ERROR in ./node_modules/xlsx-style/ods.js Module not found: Error: Can't resolve 'fs' in 'D:\PD\service\angular\node_modules\xlsx-style'

These errors was coming after upgrade from Angular 5 to 6 as well.

Please help me how i can solve this ?

Already tried solutions but not working :

  • node: { fs: "empty" } in webpack.config.js

  • "browser": { "fs": false, "os": false, "path": false } in package.json
