Error deploying sync to SF Sandbox (npm run crm-sync:sf:org:deploy) about b2c-crm-sync HOT 3 CLOSED

Update on error:

Used the fix referenced by another user @regist84 in a previous post:
i bypass this error modifing the file "/home/ranosys/Downloads/b2c-crm-sync/b2c-crm-sync/node_modules/@oclif/core/lib/command.js".
I changed the row 6 from "const cli_ux_1 = require("cli-ux");" to "const cli_ux_1 = require("../../../cli-ux");"

Now getting a new error message:
_[

FYI - this is a SF sandbox and cannot enable DevHub

How do we deploy to a SF sandbox without enabling the DevHub?

Solved by entering same credentials in the ENV file for the DevHub credentials.
