因为需要在一台访问外网受限的Ubuntu主机上安装pytest，记录一下如何生成离线依赖包。
准备
- 先找一台可以接入外网的主机
- 更换pypi源
root@eve-ng:~/deb_package# vim ~/.pip/pip.conf
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[global]
index-url =
[install]
use-mirrors = true
mirrors = http://mirrors.aliyun.com/pypi/simple/
trusted-host=mirrors.aliyun.com
生成
- 安装python-pip并升级
root@eve-ng:~# mkdir pkg_py
root@eve-ng:~# cd pkg_py/
root@eve-ng:~/pkg_py# apt install pip
root@eve-ng:~/pkg_py# pip install --upgrade pip
- 获取pytest的离线包和依赖包
root@eve-ng:~/deb_package# pip download -d ./ pytest==3.3.0
...
root@eve-ng:~/pkg_py# ls -l

排障
- 上网查资料发现，是因为attrs的版本19.3.0不适合，需要切换到19.1.0
- 下载attrs==19.1.0
root@eve-ng:~/pkg_py# pip download attrs==19.1.0
- 安装
root@eve-ng:~/pkg_py# pip install attrs-19.1.0-py2.py3-none-any.whl

小结
- 将requirements.txt中的attrs的版本修改为19.1.0
root@eve-ng:~/pkg_py# cat requirements.txt
attrs-19.1.0-py2.py3-none-any.whl
funcsigs-1.0.2-py2.py3-none-any.whl
pluggy-0.6.0-py2-none-any.whl
py-1.8.1-py2.py3-none-any.whl
pytest-3.3.0-py2.py3-none-any.whl
setuptools-44.1.0-py2.py3-none-any.whl
six-1.14.0-py2.py3-none-any.whl
root@eve-ng:~/pkg_py#
- 将pkg_py打包发到不能访问外网的主机上，按照requirements.txt安装
# pip install --no-index --find-links=./ -r requirements.txt
