一、背景

眾所周知，root用戶在linux系統(tǒng)中擁有至高無(wú)上的權(quán)力，為所欲為，想干嘛就干嘛。所以當(dāng)然不能隨隨便便給人家用root賬戶去搞事情啊，這里就有了用普通用戶安裝使用python的想法，一起來(lái)看看吧。

二、前期準(zhǔn)備

更新下源，并安裝相應(yīng)的更新

sudo apt-get install upgrade && apt-get install update

安裝相關(guān)的編譯輔助工具

sudo apt-get install make build-essential zlib1g-dev  -y

-y表示不用你確認(rèn)了，告訴ubuntu你直接給我裝完就行

源碼包下載

認(rèn)準(zhǔn)這個(gè)網(wǎng)站哦，https://www.python.org/downloads/source/，當(dāng)然你再細(xì)心觀察下，直接訪問(wèn)這里不是更快嗎？https://www.python.org/ftp/python/

三、安裝（以3.8.1為例）

下載相應(yīng)的Python源碼包，這里我們用wget一步到位

wget https://www.python.org/ftp/python/3.8.1/Python-3.8.1.tgz

對(duì)下載下來(lái)的Python源碼包進(jìn)行解壓

tar -zxvf Python-3.8.1.tgz

這里為了便于管理，我們?cè)诋?dāng)前用戶家目錄下新建software表示我們要裝的軟件，一步到位我們就定義好安裝python的目標(biāo)文件夾了

mkdir -p /home/ataola/software/python3.8

進(jìn)入到解壓后的源碼目錄進(jìn)行編譯安裝

cd Python-3.8.1./configure --prefix="/home/ataola/software/python3.8"make && make install

追加到當(dāng)前用戶環(huán)境變量

# 打開(kāi)文件vim ~/.bashrc# 視具體情況粘貼樓下這句話export PATH=PATH/software/python3.8/bin:$PATH# 保存退出 按RSC， 然后輸入:wq# 更新使其生效source ~/.bashrc

驗(yàn)證一下吧

ataola@ataola-ubuntu:~$ python3 -VPython 3.8.1ataola@ataola-ubuntu:~$ pip3 -Vpip 19.2.3 from /home/ataola/software/python3.8/lib/python3.8/site-packages/pip (python 3.8)ataola@ataola-ubuntu:~$ python -VPython 3.8.1ataola@ataola-ubuntu:~$ pip -V
Command 'pip' not found, but can be installed with:
apt install python3-pipPlease ask your administrator.
ataola@ataola-ubuntu:~$

這里你會(huì)發(fā)現(xiàn)每次都要輸入pip3，輸入pip沒(méi)用。你只需在環(huán)境變量加個(gè)別名就好

# 打開(kāi)文件vim ~/.bashrc
# 貼下面的話，視個(gè)人配置alias pip=/home/ataola/software/python3.8/bin/pip3.8
# 保存退出 按RSC， 然后輸入:wq
# 更新使其生效source ~/.bashrc

這樣不就好了嘛

ataola@ataola-ubuntu:~$ python -VPython 3.8.1ataola@ataola-ubuntu:~$ python3 -VPython 3.8.1ataola@ataola-ubuntu:~$ pip -Vpip 19.2.3 from /home/ataola/software/python3.8/lib/python3.8/site-packages/pip (python 3.8)ataola@ataola-ubuntu:~$ pip3 -Vpip 19.2.3 from /home/ataola/software/python3.8/lib/python3.8/site-packages/pip (python 3.8)ataola@ataola-ubuntu:~$

不高興按樓上一步一步來(lái)，我這里貼了一份.bashrc，你直接看著改吧

# ~/.bashrc: executed by bash(1) for non-login shells.# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)# for examples

搞完以后，這是國(guó)內(nèi)環(huán)境啊，首先想到的是換源啊，不然每次都等個(gè)半死，時(shí)間都浪費(fèi)了，阿里、豆瓣、清華源隨便選一個(gè)吧。

# 升級(jí)pippip install --upgrade pip
# 如果沒(méi)有.pip文件創(chuàng)建，有就略過(guò)mkdir ~/.pip
# 編輯配置文件vim ~/.pip/pip.conf

粘貼如下內(nèi)容

[global]index-url=http://mirrors.aliyun.com/pypi/simple[install]trusted-host=mirrors.aliyun.com

注意這里是走h(yuǎn)ttp的，因?yàn)樽铋_(kāi)始編譯的時(shí)候沒(méi)有選--with-ssl，當(dāng)然你完全可以重新編譯一次帶上這個(gè)ssl./configure --prefix="/home/ataola/software/python3.8" --enable-optimizations --with-ssl，后面就可以用https了

四、使用

輸入Python，隨便打點(diǎn)什么吧

ataola@ataola-ubuntu:~$ pythonPython 3.8.1 (default, Dec 11 2021, 19:38:06)[GCC 9.3.0] on linuxType "help", "copyright", "credits" or "license" for more information.>>> import thisThe Zen of Python, by Tim Peters
Beautiful is better than ugly.Explicit is better than implicit.Simple is better than complex.Complex is better than complicated.Flat is better than nested.Sparse is better than dense.Readability counts.Special cases aren't special enough to break the rules.Although practicality beats purity.Errors should never pass silently.Unless explicitly silenced.In the face of ambiguity, refuse the temptation to guess.There should be one-- and preferably only one --obvious way to do it.Although that way may not be obvious at first unless you're Dutch.Now is better than never.Although never is often better than *right* now.If the implementation is hard to explain, it's a bad idea.If the implementation is easy to explain, it may be a good idea.Namespaces are one honking great idea -- let's do more of those!>>>

python吧，就是包庫(kù)多，有的時(shí)候我們可能期望 a和b組合做一個(gè)實(shí)驗(yàn)或者開(kāi)發(fā)，有的時(shí)候期望是a和c組合，那么這里推薦你用virtualenv

# 安裝virtualenvpip install virtualenv
# 創(chuàng)建項(xiàng)目文件并進(jìn)入mkdir play-py-a && cd play-py-a
