在Mac上创建应用程序时无法启用Python虚拟环境

Question

I am following instruction to create Mac app with Python. I was installing Virtualenv as a part of it, as here says. I successfully did till second step; pip install, bash_profile. But when I try to Enable the virtual environment part, I get a. no file or directory / b&c. command not found, for each step.

By the way, this is the first time I heard .bash_profile, so the script is empty except what I did at the second step.

How can I fix the problem?

Answer 1

Follow simple steps

1. pip install virtualenv
2. virtualenv venv # venv is your desired name
3. source venv/bin/activate

Answer 2

I suggest you read Virtualenv User Guide .

1. Install virtualenv by using pip install virtualenv

2. virtualenv ENV to create virtual environment.

   Where ENV is a directory to place the new virtual environment.

3. source bin/activate to activate script.

4. And type deactivate to undo the changes.

virtualenvwrapper

Add three lines to your shell startup file ( .bashrc , .profile , etc.) to set the location where the virtual environments should live, the location of your development project directories, and the location of the script installed with this package:

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh

Run source ~/.bashrc to reload the startup file.
