sfdx command not working after installing salesforce CLI

Question

I installed salesforce cli and when I run the sfdx command on the command window, I am getting this error:

PS C:\\Users\\as67934\> sfdx
node:internal/modules/cjs/loader:1247
throw err;
^\

    Error: Cannot find module 'C:\Users\as67934\undefined'
    at Function._resolveFilename (node:internal/modules/cjs/loader:1244:15)
    at Function._load (node:internal/modules/cjs/loader:1070:27)

    at node:internal/main/run_main_module:36:49 {

requireStack: \[\]
}\

I tried reinstalling salesforce cli and VS Code still getting the same error. Do we need node.js to be installed for this?

Even I faced the same problem a few hours ago.
Got to know the sdfx command is old and not supported in certain OS.
Try using sf instead.
Worked for me!
