Can'；t在RHEL上通过pyenv安装python

在RHEL7.6上安装了

pyenv

根据需要安装必要的库

检查可用安装列表

$ pyenv install --list | grep 3.8.2
  3.8.2

安装时出现错误：

$ pyenv install 3.8.2
Downloading Python-3.8.2.tar.xz...
-> https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tar.xz
error: failed to download Python-3.8.2.tar.xz

BUILD FAILED (Red Hat Enterprise Linux Server 7.6 using python-build 1.2.18-7-gae4d489)

甚至尝试设置代理，但仍然出现相同的错误

操作系统信息是

$ cat /etc/os-release

ID_LIKE="fedora"

尝试从

https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tar.xz

并将其放入pyenv缓存

$（pyenv root）/cache/

然后重试

pyenv安装3.8.2
