解决docker-compose启动时urllib3报错的问题

2017-08-31

使用pip安装了docker-compose之后，启动时报了如下如下错误

Traceback (most recent call last):

在谷歌上查了一下，发现GitHub上有人报过类似issue，结果发现要升级urllib3的版本，还要需改一下path

1	pip install urllib3==1.14

and

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

另外，如果是系统初装，urllib3会报insecure的错误

1	apt-get install python-openssl

完美解决

发现了一个可以避免的办法，就是不使用ubuntu自带的pip安装

1 2	sudo easy_install pip pip install docker-compose
