Question

我正在尝试在我的Ubuntu 14.04计算机上第一次安装和使用docker-compose，但我失败了:)）

我已经使用

通过pip安装了docker-compose

当我尝试运行docker-compose up时，我收到此错误跟踪：

    Traceback (most recent call last):

    urllib3.connection.match_hostname = match_hostname
AttributeError: 'module' object has no attribute 'connection'

鸡蛋版本：

$pip freeze | grep -e urllib3 -e requests -e docker-py                                    
docker-pycreds==0.2.1
requests==2.13.0
urllib3==1.14

我试图像这样导出PYTHONPATH：

export PYTHONPATH=/usr/local/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages

我猜你有多个不同版本的软件包。

请求和urllib3都可以存在于/usr/lib/python2.7/dist-packages/和/usr/local/lib/python2.7/dist-packages

中

在ssladapter.py中，先前导入了request.packages.urllib3： try: import requests.packages.urllib3 as urllib3 except ImportError: import urllib3

如果您的requests.packages.urllib3太旧，则会引发错误。

所以你有两种方法来解决这个问题

将最新的urllib3复制到requests / packages
删除请求/包中的urllib3，以便docker-compose将使用pythonpath中的urllib3（最新的urllib3）

（您可以通过交互式控制台获取请求的路径：

>>> import requests
>>> requests
<module 'requests' from '/usr/lib/python2.7/dist-packages/requests/__init__.pyc'>

）
