Anaconda virtual environment migration

Because the lab has several servers at the same time, it is necessary to configure the same virtual environment without the server, so the migration of the virtual environment is considered, which is absolutely successful.

Reference link: On different Ubuntu servers, Anaconda's python virtual environment migration_qq_34292087's blog - CSDN blog

Premise introduction
Ubuntu18.04
anaconda3.5
Migration target: python3.6 (ie env1 in the above figure)
anaconda can manage multiple virtual environments, in the anaconda/envs directoryDown.If on server 1, we have 5 python environments (as shown above), we now need to copy env1 to the new server 2

Migration process

1. Copy anaconda/envs/env1 on server 1 to anaconda/envs on server 2

My environment name here is: Third

cd ~/anaconda3/envsscp -r [email protected] server IP:~/anaconda3/envs/Third ./

2. Modify the pip file.The specific path of pip: ~/anaconda3/envs/env1/bin/pip or pip3 (preferably change both)
The absolute path of python in the first line needs to be modified correctly!!!(Otherwise pip install will report an error)

#!/home/lcf/anaconda3/envs/Third/bin/python# -*- coding: utf-8 -*-import reimport sysfrom pip._internal.cli.main import mainif __name__ == '__main__':sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])sys.exit(main())

Change the "#!/home/lcf/anaconda3/envs/Third/bin/python" in the first line to the path of the destination environment
