gclient issue when building Chromium on Windows

Question

I'm following steps on https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md to build Chromium on Windows, when it comes to run gclient , it gives following usage information, it seems something is wrong, any suggestion is appreciated.

C:\Users\Test>gclient

Usage: gclient.py [options]

Meta checkout dependency manager for Git.

Commands are: config creates a.gclient file in the current directory diff displays local diff for every dependencies fetch fetches upstream commits for all modules flatten flattens the solutions into a single DEPS file getdep gets revision information and variable values from a DEPS file grep greps through git repos managed by gclient help prints list of commands or help for a specific command metrics reports, and optionally modifies, the status of metric collection pack generates a patch which can be applied at the root of the tree recurse operates [command args...] on all the dependencies revert reverts all modifications in every dependencies revinfo outputs revision info mapping for the client and its dependencies root outputs the solution root (or current dir if there isn't one) runhooks runs hooks for files that have been modified in the local working copy setdep modifies dependency revisions and variable values in a DEPS file status shows modification status for every dependencies sync checkout/update all modules validate validates the.gclient and DEPS syntax verify verifies the DEPS file deps are only from allowed_hosts

Options: --version show program's version number and exit -h, --help show this help message and exit -j JOBS, --jobs=JOBS Specify how many SCM commands can run in parallel; defaults to 8 on this machine -v, --verbose Produces additional output for diagnostics. Can be used up to three times for more logging info. --gclientfile=CONFIG_FILENAME Specify an alternate.gclient file --spec=SPEC create a gclient file containing the provided string. Due to Cygwin/Python brokenness, it can't contain any newlines. --no-nag-max Ignored for backwards compatibility.

When I try it in a clean system, it works.
