如何把外网python虚拟环境迁移到内网
外网python2.7虚拟环境中安装了flask模块，期望在内网使用，如何迁移外网的虚拟环境到内网呢？
1进入外网python虚拟环境
[root@localhost20200422]#sourcepython27_virtual_env/bin/activate
(python27_virtual_env)[root@localhost20200422]#
2导入虚拟环境中已安装包的信息到requirements.txt文件中
(python27_virtual_env)[root@localhost20200422]#pipfreeze--all>requirements.txt
3创建一个临时目录，将安装包下载到该目录下
(python27_virtual_env)[root@localhost20200422]#mkdirwhls
(python27_virtual_env)[root@localhost20200422]#cdwhls
(python27_virtual_env)[root@localhostwhls]#pipdownload-r../requirements.txt-d.
(python27_virtual_env)[root@localhostwhls]#ll

4将创建好的虚拟环境打包，拷贝到新的环境中
5解压，激活该虚拟环境
6将whls目录拷贝解压到新环境的目录下
7执行安装命令安装
pipinstall--no-index--find-links=your_offline_packages-rrequirements.txt
