Did you try Googling the error message?

i tried but didn’t find solution

Do you understand the error and what the problem is?

What did you do to try and solve it?

  1. You should update the packages/libraries/framework. Updated versions should work.

  2. If you have access to the Webpack config you can change the output.hashFunction

  3. Hacky workarounds would included, downgrading Node.js (V16) or forcing --openssl-legacy-provider in the start script (when/if applicable)

I don’t use Angular and can’t give you any specific instructions for it.

i’m Really Thank You, It’s Worked after i change the nodejs version to 16.0.0,
ant use the command

export NODE_OPTIONS=--openssl-legacy-provider

i’m in this problem from Six hours later, Thank You

which file i should add ```
export NODE_OPTIONS=–openssl-legacy-provider

?
