我正在尝试运行docker-compose（通过 安装pip），但遇到以下错误：
# pip install --quiet docker-compose
# docker-compose ps

有没有办法强制docker-compose使用 python3 而不是python（python2）？
@Micromegas/@MikaelH
# apt-get -q install python3-pip
# pip3 install --quiet docker-compose
# docker-compose ps

答案1
这是 pyrsistent 的最新版本 (0.17.0) 的问题。
您应该安装过去的版本。
pip uninstall pyrsistent
pip install pyrsistent==0.16.0
答案2
我不知道这是否能解决您的问题，但我希望它能帮助您解决问题。我遇到了同样的问题，但我试图pip install docker-compose在我的 gitlab CI 中运行。
我之前出现问题的配置是这样的：
- apk update
- apk upgrade
- apk add python python-dev py-pip build-base libffi-dev openssl-dev libgcc
- pip install docker-compose
为我修复此问题的方法是：
- apk update
- apk upgrade
- apk add build-base libffi-dev openssl-dev libgcc
- apk add python3
- apk add python3-dev
- apk add py3-pip
- pip3 install docker-compose
所以我认为@MikaelH 的评论是正确的。尝试更新到 pip3 并确保安装了必要的依赖项。这取决于您的环境/系统。如果您使用的是 Debian，则可以使用sudo apt-get install python3，sudo apt-get install python3-pip等等sudo apt-get install python3-dev libffi-dev libssl-dev...
答案3
由于 Python 2 现已停用，因此应使用 Python 3 版本的 pip 来安装 docker-compose。在 Debian 或 Ubuntu 上，可以使用以下命令安装：
apt-get install python3-pip
之后可以使用 Python 3 pip 版本安装 Docker Compose
pip3 install docker-compose
