今天在编译一个docker项目到时候，遇到了很多问题。记录一下
架构：Python+Django+bootstrap+SaltStack+Zabbix+MySQL
1 bash: docker-compose: command not found...
[root@localhost mysite]# docker-compose build bash: docker-compose: command not found... [root@localhost mysite]# pip -V bash: pip: command not found...

[root@localhost mysite]# pip install six --user -U ImportError: No module named configparser
很多关于configparser，说是python 3.x修改了名字

还是不行，于是把python2换成python3.6试试

安装docker-compose
方法1（在线安装，网络问题） # yum -y install libcurl libcurl-devel # curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose # chmod +x /usr/local/bin/docker-compose # docker-compose --version 方法2 安装python-pip yum -y install epel-release yum -y install python-pip 安装docker-compose pip install docker-compose pip install -U docker-compose==1.23.2 方法3 离线安装 https://github.com/docker/compose/releases/tag/1.23.2 下载安装包docker-compose-Linux-x86_64 [root@localhost opt]# mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose mv: overwrite ‘/usr/local/bin/docker-compose’? y [root@localhost opt]# chmod +x /usr/local/bin/docker-compose [root@localhost opt]# docker-compose --version Traceback (most recent call last): File "/usr/bin/docker-compose", line 5, in <module> from compose.cli.main import main ModuleNotFoundError: No module named 'compose'
问题依旧：
以使用国内的pip源进行加速 [root@localhost opt]# pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple -U docker-compose [root@localhost opt]# docker-compose --version docker-compose version 1.26.2, build unknown
