如果要使用virtualenv，应该在哪里找到Python文件？

Question

I have a virtual environment and I do not know where should I save my Python file ? it only works when I run it in /home/jojo/Enviroment/venv1 can I save it in other place ? Especially when I want to use PyCharm thank you

Answer 1

virtualenv and your code base can very well be in different locations. I prefer things this way. Here are sample commands that I use.

Step 1 : Activate the virtualenv.

[mayank@demo /dev]$ source /usr/local/pyenv3.4/bin/activate
(pyenv3.4)[mayank@demo dev]$ 

Notice the prefix "(pyenv3.4)" that indicates that virtualenv is now activated.

Step 2 : Ensure that python executable in virtualenv is indeed pointed by "python"

(pyenv3.4)[mayank@demo dev]$ which python 
/usr/local/pyenv3.4/bin/python

Notice that python is indeed pointing to the one in virtualenv directory.

Step 3 : Create a file elsewhere and execute it

echo "import sys; print(sys.executable)" > /tmp/print_python_exe.py
python /tmp/print_python_exe.py

Edit: As suggested by Paul, one might choose to keep the virtualenv directory inside the app directory. This style of structuring projects is also suggested here: http://docs.python-guide.org/en/latest/dev/virtualenvs/#basic-usage
