Use lodash version 4.17.5 works for me.

I am using typescript version 4.6.4 and lodash version 4.17.5.

Uninstall the current version (4.17.6) and reinstall 4.17.5 version

npm uninstall @types/lodash

npm install @types/lodash@4.17.5

Then, the ng build should work

try this

"@types/lodash": "4.14.168"

Finally ,It works like a charm ( "typescript": "4.1.5")

Upgrade typescript to v5+. Apart from this, if you're using any bundlers (e.g., Rollup, Webpack), don't forget to upgrade their TypeScript-related packages as well. I had to upgrade rollup-plugin-ts.

I faced the exact same issue.

Two problems I have:

• Lodash below version 4.17.20 has a critical security issue. So, downgrading is not an option.
• Also, I can't update typescript to version 5 because of some old modules in my project...

My solution (=compromise) was to update Typescript to version 4.7.4 and the error disappeared.

The solution which worked for him.

1. typescript version at 4.7.2.
2. Added new dependency of @types/lodash at 4.17.5 version.
