python将软件包和所有的依赖都下载到本地的目录？

实现这个功能，只需2步

 

一、下载

 

1、创建目录

 

目录用于存放包及其依赖

 

mkdir /root/rdbtools

 

 

2、安装软件

 

这里安装 rdbtools python-lzf

 

重点： --download 参数

 

pip3 install --download="/root/rdbtools" rdbtools python-lzf

 

 

注意：这个环境可以联网！

 

并没真正的安装！（pip3 list 可验证！）

 

3、查看目录

 

命令执行完成，进入目录查看

 

所有的软件包和依赖都已经下载好了。

[root@centos7 rdbtools]# ls -ltr

-rw-r--r-- 1 root root  31867 Dec  8 02:14 rdbtools-0.1.15.tar.gz
-rw-r--r-- 1 root root   9282 Dec  8 02:14 python-lzf-0.2.4.tar.gz

-rw-r--r-- 1 root root  98338 Dec  8 02:14 pyparsing-3.0.9-py3-none-any.whl
-rw-r--r-- 1 root root   5313 Dec  8 02:14 zipp-3.6.0-py3-none-any.whl
[root@centos7 rdbtools]# 

# 打包
cd ..
zip -r rdbtools.zip rdbtools

 

 

下载好，之后，如何在其他的主机上进行安装？

 

二、离线安装

 

1、上传软件及依赖包

 

解压

[root@centos7 ~]# ls -l rdbtools.zip 
-rw-r--r-- 1 root root 476530 Dec  8 02:25 rdbtools.zip
[root@centos7 ~]# 

unzip rdbtools.zip

 

 

2、本地安装

 

cd rdbtools/
pip3 install --no-index --find-links=./ rdbtools python-lzf

 

 

完成安装

[root@centos7 rdbtools]# pip3 install --no-index --find-links=./ rdbtools python-lzf

3、查看安装的包

 

[root@centos7 rdbtools]# pip3 list
