我正在尝试从谷歌运行LaunchKit以获取一些应用程序屏幕截图。我已经完成了 GitHub 页面 (https://github.com/LaunchKit/LaunchKit( 上开源代码的所有步骤。完成所有步骤并运行$ vagrant up --provision后，我得到以下内容：
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'ubuntu/trusty64' version '20190514.0.0' is up to date...
==> default: Running provisioner: ansible...
Vagrant has automatically selected the compatibility mode '2.0'
according to the Ansible version installed (2.9.2).
Alternatively, the compatibility mode can be specified in your Vagrantfile:

Python2 的当前版本是 2.7.10(高于它请求的 2.7.7+(，我还安装了 python 3 (3.7.6(。
这是我第一次在终端中深入工作。
我也尝试为 python = python3 创建一个别名，但是当调用 vagrant up 时，它似乎仍在运行 Python2 --provision。
关于如何解决这个问题的任何想法？

手动卸载冲突的软件包six 1.5.2。
可以在带有命令和剧本的托管计算机上使用 Python 3。如果您认为这将解决冲突，请将变量ansible_python_interpreter例如在清单中
ansible_python_interpreter=/usr/bin/python3
应自动选择点子版本。问题由 pip 报告。查看源代码
- name: install python requirements
pip: requirements=/vagrant/requirements.txt
点 说：
默认情况下，它使用 Ansible Python 解释器的 pip 版本。例如，python 3 上的 pip3，python 2 上的 pip2 或 pip。
