- 安装 gcc-9
yum install devtoolset-9
- 使用 gcc-9
基本用法
scl enable devtoolset-9 "要执行的其他命令"
这里开启 gcc-9 后, 进入新的 bash 交互环境执行其他命令
scl enable devtoolset-9 bash
conda activate my-env
pip install pandas==2.2.2
- (可选)配置当前登录用户的默认 gcc 版本, 如果系统里安装的东西很多, 这一步要谨慎.
vim ~/.bashrc
# 自动启用 SCL devtoolset-9 (GCC 9)
source /opt/rh/devtoolset-9/enable
背景
pandas / numpy 安装报错
pip install pandas==2.2.2
pandas 依赖 numpy, 新版本 numpy 安装, 依赖较新版本的 gcc g++. 其中,
numpy 2.3.4 需要 gcc g++ 版本 >=9.3
numpy 1.2.99 需要 gcc g++ 版本 >=8.4

直接使用系统默认安装源(如果可以访问的话,这里用了mirrors.aliyun.com镜像), gcc 版本为 4.8.5, 不满足要求
yum install gcc gcc-c++
不要把 scl enable devtoolset-9 bash 放到 .bashrc 里, 会导致嵌套循环执行
