CentOS 安装后没有看到 python3.8

Question

我在本教程的帮助下安装了 Python 的最新版本：https://computingforgeeks.com/how-to-install-python-on-3-on-centos/

"Which" 看到 python3.6 但没看到 python3.8

[nikolay@nikovm ~]$ which python3.6
/bin/python3.6
[nikolay@nikovm ~]$ which python3.8
/usr/bin/which: no python3.8 in (/home/nikolay/.local/bin:/home/nikolay/bin:/sbin:/bin:/usr/sbin:/usr/bin) 

[nikolay@nikovm ~]$ python3.8
bash: python3.8: command not found  

[nikolay@nikovm ~]$ python3.6
Python 3.6.8 (default, Nov 21 2019, 19:31:34)
[GCC 8.3.1 20190507 (Red Hat 8.3.1-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>     

[nikolay@nikovm ~]$ ls /usr/local/lib
libpython3.8.a  pkgconfig  python3.6  python3.8
[nikolay@nikovm ~]$  

[nikolay@nikovm ~]$ ls /bin/ | grep python
python3
python3.6
python3.6m
unversioned-python

[nikolay@nikovm ~]$ ls /usr/bin/ | grep python
python3
python3.6
python3.6m
unversioned-python

旧版本 python (3.6) 有效。

我重装了python3.8很多次了，还是不行。

请帮帮我）

默认情况下，CentOS python 3.8 安装到 /usr/local/bin 中，根据您 "which" 的输出，它不在您的路径中。

(/home/nikolay/.local/bin:/home/nikolay/bin:/sbin:/bin:/usr/sbin:/usr/bin)

查看 python3.8 和其他 3.8 二进制文件是否在 /usr/local/bin

内

如果是，请将其添加到您的路径

PATH=$PATH:/usr/local/bin

然后再试一次。
