问题
I'm using Python 3.4 on Windows. I have created a virtual environment with
python c:\Python34\Tools\Scripts\pyvenv.py foo
Then activated it
foo\Scripts\activate.bat
And installed several libraries in it.
Question: Is it safe to rename the venv folder "foo" to "bar"? I.e. once i have renamed foo to bar, then activate it with
bar\Scripts\activate.bat
will it still work?
What could make problems are any environment variable settings and absolute paths.
回答1:
To be able to do that you should use virtualenv. From the docs:
Normally environments are tied to a specific path. That means that you cannot move an environment around or copy it to another computer. You can fix up an environment to make it relocatable with the command:
$ virtualenv --relocatable ENV
This will make some of the files created by setuptools or distribute use relative paths, and will change all the scripts to use activate_this.py instead of using the location of the Python interpreter to select the environment.
Note: you must run this after you've installed any packages into the environment. If you make an environment relocatable, then install a new package, you must run virtualenv --relocatable again.
But be aware:
The --relocatable option currently has a number of issues, and is not guaranteed to work in all circumstances. It is possible that the option will be deprecated in a future version of virtualenv.
