• Linux中安装docker-compose
  (1）执行docker-compose时报错-bash: docker-compose: command not found
  说明没有安装docker-compose命令
  (2）安装docker-compose之前需要安装pip，通过pip -V查看是否安装pip如果报错-bash: pip: command not found 表示没有安装
  安装pip ：

yum -y install epel-release
 
yum -y install python-pip
 
#升级
pip install --upgrade pip

安装过程中或者安装完成查看pip版本时报错

Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==21.0', 'console_scripts', 'pip')()
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 378, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2566, in load_entry_point
    return ep.load()
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2260, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
  File "/usr/lib/python2.7/site-packages/pip/_internal/cli/main.py", line 60
    sys.stderr.write(f"ERROR: {exc}")

通过以下方式解决

yum remove python-pip
 
cd /usr/local/src
wget https://bootstrap.pypa.io/2.7/get-pip.py
python get-pip.py
 
pip -V

（3）安装Docker-Compose执行pip install docker-compose，如果报错
ERROR: Cannot uninstall ‘requests’. It is a distutils installed project and thus we cannot accuratel

解决方法：执行sudo pip install --ignore-installed requests即可解决
（4）执行docker-compose -version 查看安装是否成功
