使用yaml文件在虚拟环境中运行本地python脚本

Question

I want to run my local python script inside virtual environment. Here is the code I have tried. I have created virtual environment and installed Cassandra-driver as well

---
- hosts: localhost
  gather_facts: no
  connection: local
  name: install cassendra-driver
  become: true
  become_user: root
  vars:
    PROJECT_HOME: "/home/hari/Desktop/venvs"
  tasks:
          - name: Run a script using an executable in virtual environment
                    script: "/space/code_base/add_new_column_to_table.py"
                    virtualenv: "{{ PROJECT_HOME }}/myenv"
                    args:
                        executable: python2

But I am getting error

• ERROR! Syntax Error while loading YAML. mapping values are not allowed in this context

The error appears to be in '/home/hari/Desktop/cassendra-driver_2.yml': line 30, column 27, but may be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

      - name: Run a script using an executable in virtual environment
                script: "/space/code_base/add_new_column_to_table.py"
                      ^ here

Could some one help me?

My requirement is to run local python script inside virtual environment.

I don't have access to your environment, but something like this should work:

tasks:
- command: {{ PROJECT_HOME }}/myenv/bin/python /space/code_base/add_new_column_to_table.py
