linux升級python
能在線用yum安裝更新就用yum,不能就下載個新版本的rpm包,用rpm命令,安裝上就OK了。
② linux 修改默認Python為Python3
先查看自己電腦里的python3版本:
在個人的home目錄中,打開 *.bashrc*文件,打開方式為
沒有安裝gedit文本編輯器的使用如下命令安裝
或者使用vim、nano等。打開後,輸入如下內容:
然後注銷登錄或者輸入如下命令以使命令立刻生效
先刪除默認的Python軟鏈接:
然後創建一個新的軟鏈接指向需要的Python版本:
如果想還原回原python2.7,只需
注意,ln命令的基本用法為:
直接執行下面兩個命令即可:
如果需要改回python2默認,則輸入:
完畢。
③ linux怎麼升級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達到你的要求, 你可以去python.org下載最新版並手動編譯, 如果python.org里的最新版仍不能達到你的要求, 你可以對源碼進行修改編譯並測試.
④ 求助kali Linux上怎麼升級Python
操作方法如下: 1.#vim /etc/apt/sources.list 2.復制上面的軟體源到sources.list中 3.屏蔽或刪除之前的軟體源 4.退出並保存 5.運行以下命令 [html] view plain #apt-get update [html] view plain #apt-get dist-upgrade 6.運行重啟...

⑥ linux python 升級後 怎麼用pip安裝模塊
linux版本太老了。升級一下也很容易。通常升級到2.7就可以了。然後重新安裝cx_Oracle到python2.7目錄里。不過你的arcgis既然有自己的python解釋器,也當然有自己的包管理。你其實不需要重新安裝python2.7隻需要在arcgis環境里,執行它那個python2.7解釋器,安裝一個cx_Oracle到它自己的包管理目錄里就可以了。
⑦ 求助kali Linux上怎麼升級Python
操作方法如下:
1.#vim /etc/apt/sources.list
2.復制上面的軟體源到sources.list中
3.屏蔽或刪除之前的軟體源
4.退出並保存
5.運行以下命令
[html] view plain
#apt-get update
[html] view plain
#apt-get dist-upgrade
6.運行重啟命令即可。(#reboot)
⑧ red hat怎麼升級python
從今天開始學習Python!看了一下虛擬機RedHat中的python,發現還是原生的2.4.3,所以決定升級一下
[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.下載z最新版本的python
[root@linuxidc ~]# wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tgz
2.解壓及編譯
[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.覆蓋原有的python鏈接
[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.
>>>
此時已經可以正常使用python2.7了,但是因為yum是使用的2.4的版本來用的,現在輸入一下yum就會報錯
[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 #修改此處為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怎麼把python2升級到3
Python2和Python3是可以共存在同一個Linux系統上的,所以直接安裝Python3即可。而且Python2在Linux上也是非常重要的,可能你的系統上就有許多程序依賴Python2呢,所以Python2很有必要繼續保留在你的Linux系統上。
⑩ 請問如何將Linux得python3.5.2升級到python3.6-3.7啊
安裝python可使用命令sudo apt install python3,
嘗試使用sudo apt upgrade python來更新。
拓展:
sudo apt install <包名>可安裝軟體;
sudo apt upgrade <包名>可升級軟體;
sudo apt autoremove <包名>可卸載軟體
