docker-compose的pkg_resources.DistributionNotFound错误对应

这里写图片描述

docker-compose是python写的，使用pip install docker-compose安装的docker-compose有的时候会提示pkg_resources.DistributionNotFound的错误信息，
很多时候都是由于backports.ssl_match_hostname版本的问题，升级backports.ssl_match_hostname一般可以解决该问题。

现象

[root@liumiaocn ~]# docker-compose versionTraceback (most recent call last):  File "/usr/bin/docker-compose", line 5, in <module>    from pkg_resources import load_entry_point  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 3011, in <module>    parse_requirements(__requires__), Environment()  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 626, in resolve    raise DistributionNotFound(req)pkg_resources.DistributionNotFound: backports.ssl-match-hostname>=3.5[root@liumiaocn ~]#

升级backports.ssl_match_hostname

[root@liumiaocn ~]# pip install backports.ssl_match_hostname --upgradeCollecting backports.ssl_match_hostname  Downloading backports.ssl_match_hostname-3.5.0.1.tar.gzInstalling collected packages: backports.ssl-match-hostname  Found existing installation: backports.ssl-match-hostname 3.4.0.2    Uninstalling backports.ssl-match-hostname-3.4.0.2:      Successfully uninstalled backports.ssl-match-hostname-3.4.0.2  Running setup.py install for backports.ssl-match-hostname ... doneSuccessfully installed backports.ssl-match-hostname-3.5.0.1[root@liumiaocn ~]#

结果再确认

[root@liumiaocn ~]# docker-compose versiondocker-compose version 1.8.1, build 878cff1docker-py version: 1.10.4CPython version: 2.7.5OpenSSL version: OpenSSL 1.0.1e-fips 11 Feb 2013[root@liumiaocn ~]#
