 hucy_Bioinfo 2021-08-19

安装python

windows下面的Python安装一般是通过软件安装包安装。下载地址:
https://www./downloads /  

WIN+R→cmd

python

添加环境变量:鼠标右键此电脑  -> 属性 -> 点击高级系统设置 -> 点击环境变量 -> 点击PATH -> 在最后面加上Python的安装路径 -> 点击确定。

安装pip

官网下载:https://pypi./pypi/pip#downloads   

下载完成之后,解压到一个文件夹,用CMD控制台进入解压目录,输入:

python setup.py install

安装好之后,直接在命令行输入pip,同样会显示'pip’不是内部命令,也不是可运行的程序。需添加环境变量:D:Program Filespython3.6.5Scripts
