Pip 在 Python 3.5 上的安装速度明显慢于 2.7 (RHEL)



我目前运行的是Red Hat 7.3，并从SCL(www.softwarecollections.org/en/scls/rhscl/rh-python35/)安装了Python 3.5。当我尝试 pip 安装 C 密集型软件包(如 numpy 和 pandas)时，Python 3.5 上的安装过程比我尝试在本机 Python 2.7 安装中安装相同软件包时花费的时间要长得多(每个包 6 分钟对 ~10 秒)。

我有一些自动化流程，这些流程经常构建和重建虚拟环境，因此这对整体性能产生了巨大影响。有谁知道为什么这些安装在 Python 3.5 中需要更长的时间？任何帮助将不胜感激。

这是两个版本上的"pip install numpy -v"的片段。我跳出的明显事情是 3.5 而不是 2.7 中出现的 GCC 大楼，但我不确定为什么......

我注意到了相同的行为，但似乎可以通过升级 pip 来解决。

默认情况下，rh-python35 似乎附带 pip 7.1.0，pip 警告 9.0.1 可用。升级到此版本似乎可以解决 numpy(以及其他具有类似问题的软件包)的问题，该软件包现在可以快速安装，并且具有与 Python 2.7 类似的日志签名：

[confuser@es-node-0 ~]$ python -m venv myenv
[confuser@es-node-0 ~]$ source myvenv/bin/activate
(myvenv) [confuser@es-node-0 ~]$ pip --version
pip 7.1.0 from /home/confuser/virtso/lib64/python3.5/site-packages (python 3.5)
(myvenv) [confuser@es-node-0 ~]$ pip install --upgrade pip
You are using pip version 7.1.0, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
