python-pycharm-py库的安装配置

windows下安装python

一、下载

https://www.python.org/downloads/

二、安装

1.双击安装

2.需要注意，记住安装的路径，如我的安装地址C:\Users\Administrator\AppData\Local\Programs\Python\Python37

三、环境配置

1、为什么要进行环境配置

1）计算机在执行命令的时候是在环境变量找对应的命令的位置的。如果不正确设置环境变量就不能正确使用相应的命令
2）比如说你要执行python 命令，你不设置环境变量path包括你的python安装路径，那系统去哪找你的python.exe文件。

C:\Users\Administrator\AppData\Local\Programs\Python\Python37\python.exe
3）如果执行某个命令，系统无法在当前文件夹里找到对应的.exe，那么系统就会去path包含的路径找挨个找看是否能知道对应的.exe，一旦找到第一个对应的.exe就运行命令，其他的路径下就不找了。如果找不到你就会看到“系统找不到某某命令”的提示

2、怎么配置环境

我的电脑—>右键属性—>系统设置—>系统变量—>Path—>编辑，把上面python的路径填入

四、检查安装配置情况

打开cmd

输入python，如果出现版本以及一下信息说明python环境变量配置成功

centos下安装python3

1.安装rz、sz

yum -y install lrzsz

curl -O https://ohse.de/uwe/releases/lrzsz-0.12.20.tar.gz

更换yum镜像（/etc/yum.repos.d/CentOS-Base.repo）

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
#

yum clean all

yum makecache

1.下载Python-3.7.5.tgz
https://www.python.org/ftp/python/3.7.5/

curl -O https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz

2.上传到指定文件解压

rz Python-3.7.3.tgz /usr/local/lib

tar -zxvf Python-3.7.3.tgz

3.编译前提

yum install -y gcc（必须用gcc编译）

python3 -c "import ctypes; print(ctypes.__file__)" 判断_ctypes

yum install libffi-devel -y（下载第三方库报错：ModuleNotFoundError: No module named ‘_ctypes）

yum install zlib-devel

yum install openssl

4.编译

/usr/local/lib/Python-3.7.5 ./configure --prefix=/usr/local/lib/python37

/usr/local/lib/Python-3.7.5 make

/usr/local/lib/Python-3.7.5 make install

ln -s /usr/local/lib/python37/bin/python3.7 /usr/local/bin/python3

安装python第三方库

一、通过命令进行单个或者批量安装

1.升级pip3等（确定pip为24.0版本）

python3 -m pip install --upgrade pip setuptools wheel -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com

2.pip3下载第三方库

python3 -m pip list 查看已安装的第三方库

python3 -m freeze > centos_requirements.txt 导出依赖到 requirements.txt

python3 -m pip install moviepy==1.0.3 -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com 安装单个第三方库

python3 -m pip install -r centos_requirements.txt -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com 批量安装第三方库

二、手动安装

1.下载

https://pypi.org/project/selenium/（选择扩展名为gz的源码包进行下载）

2.解压

下载后解压，cmd环境进入到setup.py文件所在目录

3.安装

4.检查安装是否成功

用import selenium引入selenium包了，没有报错

三、通过pycharm安装

安装pycharm

一、前言：

在写脚本之前，先要找个顺手的写脚本工具。python是一门解释性编程语言，所以一般把写python的工具叫解释器。写python脚本的工具很多，小编这里就不一一列举的，只要自己用着顺手就可以的，如果你还没有选好解释器，小编这里推荐pycharm。

在安装pycharm后，有一些小伙伴不会破解，这里小编还是推荐大家买正版的。当然，如果你不想付费，想破解pycharm，也是很容易的事情，这里小编列举几种破解办法。前提是你要先下载pycharm安装包，安装包可以去官网http://www.jetbrains.com/pycharm/下载最新版。

二、下载

https://www.jb51.net/softs/598511.html

三、安装

1.双击软件，下一步一直操作直到完成

2.注册（破解）

链接: https://pan.baidu.com/s/1_6o88o1IqLj5rkoq0behWw 提取码: m86n

方法一：

1）在注册界面，选择License serve。填入http://idea.lanyus.com/71

2）点击ok

方法二：

1）注册界面选择：Activationcoede

2）打开网址：http://idea.lanyus.com/71，点击“获取注册码”按钮

3）复制弹出框的注册码

4）copy到注册界面Activationcoede位置

方法三：

1）下载激活插件：jetbrains-agent.jar，并将jetbrains-agent.jar放到PyCharm安装目录bin下面，例如D:\Program Files\JetBrains\PyCharm 2019.1\bin。

2）首次安装的Pycharm，需要点击激活窗口的Evaluate for free免费试用，然后再创建一个空项目进入主页窗口。

3）在菜单栏Help中选择Edit Custom VM Options …

在最后一行添加：

-javaagent:C:\Program Files\JetBrains\PyCharm 2018.2.4\bin\jetbrains-agent.jar

4）修改完成后，重启Pycharm，点击菜单栏中的 “Help” -> “Register”，输入激活码完成完成激活，这里的激活码与方法一种激活码不同。

5）查看有效期的步骤：点击：Help->About，这里可以看到你的pycharm有效期到2089年了，是不是soeasy。

四、使用编写代码

1、新建脚本

1）在pycharm左侧菜单树右键，新建一个Directory(文件夹)。

2）选择对应文件夹，在文件夹中新建Python File(脚本文件)。

3）脚本名称自己命名，后缀.py会自动带出

2、开始编程

1）双击打开需要编写的脚本

2）在右侧编辑框输入：print("hello world!")

3）点脚本的title，右击后选择Run“test01”,运行结果如下
