Docker-compose啟動失敗

Question

我試圖在我的Ubuntu 14.04計算機上首次安裝和使用docker-compose，但我失敗了:)）

我已經通過使用pip安裝了docker-compose

當我嘗試運行docker-compose up以下錯誤跟蹤：

    Traceback (most recent call last):
  File "/usr/local/bin/docker-compose", line 7, in <module>
    from compose.cli.main import main

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

雞蛋版本：

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

我試圖像這樣導出PYTHONPATH：

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

我想您有多個具有不同版本的軟件包。

request和urllib3都可以存在於/usr/lib/python2.7/dist-packages/和/usr/local/lib/python2.7/dist-packages

在ssladapter.py中，request.packages.urllib3事先是根據以下方式導入的： try: import requests.packages.urllib3 as urllib3 except ImportError: import urllib3

如果您的requests.packages.urllib3太舊，將引發錯誤。

因此，您有兩種方法可以解決此問題

1. 將最新的urllib3復制到請求/包中

2. 刪除請求/包中的urllib3，以便docker-compose將使用pythonpath中的urllib3（您最新的urllib3）

（您可以通過交互式控制台獲取請求的路徑：

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