Question

我需要在一个Ubuntu 12.04上创建一些虚拟环境，然后在另一个Ubuntu 12.04上运行ansible（我无法安装任何东西（没有Internet连接）。

我尝试在虚拟环境中安装Ansible：

export venv_name="ansible_virt_env"
mkdir ~/venv && cd ~/venv
echo "Virtualenv ${venv_name} directory" > README
virtualenv --no-site-packages --prompt="ansible" ${venv_name:-venv}
. ~/venv/${venv_name:-venv}/bin/activate
~/venv/${venv_name:-venv}/bin/pip install  -U pip
~/venv/${venv_name:-venv}/bin/pip install  -U setuptools
~/venv/${venv_name:-venv}/bin/pip install ansible

但它失败了：

ansibleroot@[RDE1.3]:~/venv# ~/venv/${venv_name:-venv}/bin/pip install  -U setuptools
Collecting setuptools

/root/venv/ansible_virt_env/include/site/python2.7/cffi：在pkg-config搜索路径中找不到包libffi。也许你应该添加包含`libffi.pc＆＃39;的目录。到PKG_CONFIG_PATH环境变量没有包＆＃39; libffi＆＃39;发现在pkg-config搜索路径中找不到包libffi。

我安装了libffi-dev： apt-get install libffi-dev

and ansible doen work： /根/ VENV / ansible_virt_env / bin中/ ansible 错误！意外的例外：jinja2 完整的追溯是：

但是jinja2出现了：

Answer 1

嗨，您需要安装此版本： pip install paramiko == 1.10 点子安装Jinja2 == 2.2

Answer 2

对于它的价值，我在ansible 2.1.0.0（通过pip安装），Jinja 2.8，paramiko 2.0.1中遇到了同样的问题。将ansible更新为2.2.1.0解决了问题（导致Jinja2更新到2.8.1）。

如何在virtualenv中安装ansible？
