Linux Mint 21.2下pyenv安装Python3.6.6失败求助

解决步骤 #

1. 安装编译依赖 #

先补全Python编译所需的系统依赖包：

sudo apt update
sudo apt install build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl git

2. 规避ensurepip报错安装Python #

Python 3.6.6与Linux Mint 21.2搭载的新版编译器存在兼容性冲突，禁用ensurepip模块绕开段错误：

PYTHON_CONFIGURE_OPTS="--without-ensurepip" pyenv install 3.6.6

如果上述命令仍报错，添加编译器兼容参数再尝试：

CFLAGS="-fno-semantic-interposition" pyenv install 3.6.6

3. 手动安装pip #

由于禁用了ensurepip，需要手动给Python 3.6.6安装pip：

pyenv local 3.6.6
curl https://bootstrap.pypa.io/pip/3.6/get-pip.py | python
