How to install modules in python (two methods, just copy and use)

Here is a brief introduction to the two methods of installing modules in python.

The first

Install the module in pycharm


I am here because it has already been installed, so this will appear.

# 安装模块
# pip install 模块名
# 可以指定安装版本 如安装requests 版本是2.25.1
# pip install requests==2.25.1

# 如果觉安装的太慢，可以用下面的方法

# 三个镜像源网址
# 阿里云镜像源 http://mirrors.aliyun.com/pypi/simple/
# 清华镜像源 https://mirrors.tuna.tsinghua.edu.cn/help/pypi/
# 豆瓣镜像源 https://pypi.doubanio.com/simple  

# 要有空格隔开！！！
# pip install -i 镜像源网址 模块名
# 同样也可以指定版本
# pip install -i https://mirrors.tuna.tsinghua.edu.cn/help/pypi/ requests==2.25.1

# 查看可以升级的包
# pip list --outdate

# 升级包
# pip install --upgrade 包名

# 卸载模块
# pip uninstall 模块名



# 我们也可以查看自己安装了多少模块
# pip list

the second

Win+R pops up the shortcut key to run the command, enter cmd, then press Enter, and enter in the pop-up window

# 第一种方法都能在这里使用
# pip install 模块名

# 阿里云镜像源 http://mirrors.aliyun.com/pypi/simple/
# 清华镜像源 https://mirrors.tuna.tsinghua.edu.cn/help/pypi/
# 豆瓣镜像源 https://pypi.doubanio.com/simple
# pip install -i 镜像源网址 模块名

# 卸载模块
# pip uninstall 模块名

# 我们也可以查看自己安装了多少模块
# pip list
