Standalone Couchbase CLI

Currently trying to run the Couchbase CLI tool on a separate server (for initiating backups).

I am cloning directly from the repo ( but get the below error. Is there anything special that needs to be done to use the standalone couchbase cli?

Traceback (most recent call last):
  File "./couchbase-cli", line 8, in <module>
    import cbmgr
  File "/tmp/couchbase-cli-6.5.1/", line 26
    print(f'WARNING: Could not import cb_version, setting VERSION to {VERSION}')
SyntaxError: invalid syntax

Looks like you might be running the script with Python 2? couchbase-cli requires Python 3.x.
