Inheriting environment variable PATH from vim for conda virtual environment

[NobodyXu]

I tried to use vimcmdline with conda, however it doesn't work due to the fact that the newly created python interpreter does not inherit the environment variable PATH from vim.

It works by appending /shared/conda/envs/environ_name to environment variable PATH.

So adding 'env PATH=' . $PATH when launching python through tmux should work.
