linux升级python

① linux怎么升级python版本

能在线用yum安装更新就用yum，不能就下载个新版本的rpm包，用rpm命令，安装上就OK了。

② linux 修改默认Python为Python3

先查看自己电脑里的python3版本：

在个人的home目录中，打开 *.bashrc*文件，打开方式为

没有安装gedit文本编辑器的使用如下命令安装

或者使用vim、nano等。打开后，输入如下内容：

然后注销登录或者输入如下命令以使命令立刻生效

如果想还原回原python2.7，只需

注意，ln命令的基本用法为：

直接执行下面两个命令即可：

如果需要改回python2默认，则输入：

完毕。

③ linux怎么升级python版本

如果是redhat/centos, 使用sudo yum -y update即可. 如果源里的新版本不能达到你的要求, 你可以去python.org下载最新版并手动编译, 如果python.org里的最新版仍不能达到你的要求, 你可以对源码进行修改编译并测试.

⑥ linux python 升级后 怎么用pip安装模块

linux版本太老了。升级一下也很容易。通常升级到2.7就可以了。然后重新安装cx_Oracle到python2.7目录里。不过你的arcgis既然有自己的python解释器，也当然有自己的包管理。你其实不需要重新安装python2.7只需要在arcgis环境里，执行它那个python2.7解释器，安装一个cx_Oracle到它自己的包管理目录里就可以了。

⑧ red hat怎么升级python

从今天开始学习Python!看了一下虚拟机RedHat中的python，发现还是原生的2.4.3，所以决定升级一下
[root@linuxidc ~]# python
Python 2.4.3 (#1, May 5 2011, 16:39:10)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2
Type "help", "right", "credits" or "license" for more information.
>>>
[root@linuxidc ~]#
1.下载z最新版本的python
[root@linuxidc ~]# wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tgz
2.解压及编译
[root@linuxidc ~]# tar xvf Python-2.7.2.tar.bz2
[root@linuxidc Python-2.7.6]# ./configure --prefix=/usr/local/python27
[root@linuxidc Python-2.7.6]# make
[root@linuxidc Python-2.7.6]# make install
[root@linuxidc Python-2.7.6]# ls /usr/local/python27/ -al
total 28
drwxr-xr-x 6 root root 4096 Mar 21 01:01 .
drwxr-xr-x 13 root root 4096 Mar 21 01:01 ..
drwxr-xr-x 2 root root 4096 Mar 21 01:01 bin
drwxr-xr-x 3 root root 4096 Mar 21 01:01 include
drwxr-xr-x 4 root root 4096 Mar 21 01:01 lib
drwxr-xr-x 3 root root 4096 Mar 21 01:01 share
3.覆盖原有的python链接
[root@linuxidc Python-2.7.6]# mv /usr/bin/python /usr/bin/python_old
[root@linuxidc Python-2.7.6]# ln -s /usr/local/python27/bin/python /usr/bin/
[root@linuxidc Python-2.7.6]# python
Python 2.7.6 (default, Mar 21 2014, 01:00:09)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "right", "credits" or "license" for more information.
>>>
此时已经可以正常使用python2.7了，但是因为yum是使用的2.4的版本来用的，现在输入一下yum就会报错
[root@linuxidc Python-2.7.6]# yum
There was a problem importing one of the Python moles
required to run yum. The error leading to this problem was:
No mole named yum
Please install a package which provides this mole, or
verify that the mole is installed correctly.
It's possible that the above mole doesn't match the
current version of Python, which is:
2.7.6 (default, Mar 21 2014, 01:00:09)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://wiki.linux.ke.e/YumFaq
5.修改yum
[root@linuxidc Python-2.7.6]# vim /usr/bin/yum
#!/usr/bin/python #修改此处为2.4的位置
[root@linuxidc Python-2.7.6]# vim /usr/bin/yum
#!/usr/bin/python2.4
yum 可以使用了!

⑨ linux怎么把python2升级到3

Python2和Python3是可以共存在同一个Linux系统上的，所以直接安装Python3即可。而且Python2在Linux上也是非常重要的，可能你的系统上就有许多程序依赖Python2呢，所以Python2很有必要继续保留在你的Linux系统上。

⑩ 请问如何将Linux得python3.5.2升级到python3.6-3.7啊

安装python可使用命令sudo apt install python3，
尝试使用sudo apt upgrade python来更新。

拓展：

sudo apt install <包名>可安装软件；
sudo apt upgrade <包名>可升级软件；
sudo apt autoremove <包名>可卸载软件
