how to activate virtualenv on remote host

[SysAdmin EM]

Hi all, i try activate an virtualenv on remote host but not work.

I see this error:

fatal: [wc2-prod]: FAILED! => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": true,

    },

    "stderr_lines": [
        "/bin/sh: 1: source: not found"
    ],
    "stdout": "",
    "stdout_lines": []
}

This is the tasks:

    - name: "Activating env"
      shell: . env/bin/activate
      args:
        chdir: '{{ webpath }}'

any ideas??
