HttpRunner supports Python 2.7, 3.4, 3.5, and 3.6. And we strongly recommend you to use Python 3.6.
官方强烈建议使用 Python 3.6 。
当我用 ubuntu16.04.3 默认支持的 python3.5.2 的 pip3 安装 httprunner 后
cmd@TR:~$ httprunner -V
httprunner：未找到命令
尝试添加 python3.5 的 PATH 也是无果
详见：https://github.com/HttpRunner/HttpRunner/issues/68
当然你可以有以下两种选择：
1 编译安装 python3.6 到本地某一目录 然后添加 PATH
2 利用 update-alternatives --list python 来切换系统默认 python 版本
但这两种方案 都很麻烦，且对系统自带的 py2 py3 会有影响，主要是因为 ubuntu 在升级程序 apt upgrade 的时候，有的程序依赖 py2 或 py3 如果你更改默认 py 版本，会导致升级程序出错。

https://github.com/pyenv/pyenv-virtualenv
然后看到 pyenv 方案 没有执行编译安装 py3.6.3 sudo make install 暂时该已经编译好的先放那，以后看看是否需要
pyenv + pyenv-virtualenv 还是要一起用 只用 pyenv 好像还是会有冲突问题：
但这时候， 每个版本的环境仍是唯一的， 如果我们想在环境中安装一些库的话， 还是会导致这个版本的环境被修改。 这个时候， 如果我们用 virtual env 去建立虚拟环境， 就可以完全保证系统路径的干净。无论你在虚拟环境中安装了什么程序， 都不会影响已安装版本的系统环境
以下是安装记录：
cmd@TR:~$ sudo apt-get install curl git-core
cmd@TR:~$ curl -L https://raw.githubusercontent.com/pyenv/pyenv-installer/master/bin/pyenv-installer | bash
略去部分
WARNING: seems you still have not added 'pyenv' to the load path.
# Load pyenv automatically by adding
# the following to ~/.bash_profile:
export PATH="/home/cmd/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
根据提示 需要追加 PATH 依我个人习惯我追加到了 ~/.profile
sudo gedit ~/.profile
末尾追加

export PATH="/home/cmd/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
source ~/.profile

利用 virtualenv 创建虚拟 python 环境
现在我们已经安装了多个 python 版本，但是这还不够, 某些有洁癖的程序员是一定要系统环境足够干净的，这时候我们可以使用 virtualenv 来创建虚拟 python 环境
virtualenv 本是一个独立的工具，官网在这里：https://pypi.python.org/pypi/virtualenv
幸运的是，如果你是安装我们前面的方式安装 pyenv 的，那它已经帮我们以 plugin 的形式安装好了 virtualenv, 我们只要使用就好了
首先我们创建一个 3.6.3 的虚拟环境
cmd@TR:~$ pyenv virtualenv 3.6.3 pyenv363
Requirement already satisfied: setuptools in /home/cmd/.pyenv/versions/3.6.3/envs/pyenv363/lib/python3.6/site-packages
Requirement already satisfied: pip in /home/cmd/.pyenv/versions/3.6.3/envs/pyenv363/lib/python3.6/site-packages
cmd@TR:~$ pyenv versions
system
* 3.6.3 (set by /home/cmd/.pyenv/version)
3.6.3/envs/pyenv363
pyenv363
切换和使用新的 python 虚拟环境
切换到新的虚拟环境的命令为
cmd@TR:~$ pyenv activate pyenv363
pyenv-virtualenv: prompt changing will be removed from future release. configure `export PYENV_VIRTUALENV_DISABLE_PROMPT=1' to simulate the behavior.
(pyenv363) cmd@TR:~$ python
Python 3.6.3 (default, Dec 22 2017, 09:54:35)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
如果要切换回系统环境， 运行这个命令即可
pyenv deactivate
那如果要删除这个虚拟环境呢？ 只要直接删除它所在的目录就好：
rm -rf ~/.pyenv/versions/pyenv363/
或者卸载：
pyenv uninstall pyenv363
