sudo yum update
# 下载阿里光碟源
wget https://mirrors.aliyun.com/repo/Centos-7.repo
# 下载阿里docker源
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo systemctl start docker
systemctl enable docker
sudo docker run hello-world
sudo yum install docker
sudo systemctl status docker
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
这将下载适用于您的系统的最新版本的Docker Compose。
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
您应该会看到类似于以下内容的输出:
docker-compose version 1.29.2, build unknown
恭喜!现在您已成功在CentOS上安装了Docker Compose。
除了通过下载Docker Compose二进制文件的方式安装外,还可以使用以下方法在CentOS上安装Docker Compose:
sudo yum install python3
sudo yum install python3-pip
sudo pip3 install docker-compose
docker-compose --version
您应该会看到类似于以下内容的输出:
docker-compose version 1.29.2, build unknown
恭喜!现在您已通过Python pip在CentOS上安装了Docker Compose。
请注意,在使用此方法安装Docker Compose时,可能需要指定sudo权限才能运行Docker Compose命令。
这个错误与之前的错误类似,说明在pip源代码中使用了不受旧版本Python支持的语法。具体来说,它在setup.py
文件中使用了类型注释。
[root@localhost yum.repos.d]# pip install --upgrade pip

You are using pip version 8.1.2, however version 23.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
[root@localhost yum.repos.d]#
解决此问题的一种方法是升级您的Python版本以支持类型注释。如果您无法或不想升级Python,可以尝试使用旧版本的pip进行安装,该版本没有使用类型注释。您可以通过以下命令安装旧版本的pip:
pip install --upgrade 'pip<21.0'
请注意,这将安装小于21.0版本的pip。如果您需要安装最新版本的pip,请先升级到支持类型注释的Python版本,然后再执行pip install --upgrade pip
命令进行升级。

这个错误表明在安装 bcrypt
时缺少了一个必要的依赖包 setuptools_rust
,可以通过以下步骤解决:
pip3 install --upgrade pip
setuptools_rust
:pip3 install setuptools-rust
bcrypt
:pip3 install bcrypt
如果还是出现问题,建议检查是否有其他依赖包未安装或版本不匹配。
