I wrote python3.4 in .envrc with direnv and allowed it, but I got a syntax error

I got a syntax error when I direnv allow locally on my Mac.

wakana-no-MacBook-Pro:Documents wakanayoshizawa$ cd test/
direnv: loading .envrc
Running virtualenv with interpreter /Users/wakanayoshizawa/.pythonz/pythons/CPython-3.4.3/bin/python3
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/virtualenv.py", line 37, in <module>
    import ConfigParser
ImportError: No module named 'ConfigParser'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/virtualenv.py", line 39, in <module>
    import configparser as ConfigParser

                                         ^
SyntaxError: invalid syntax

Looking at line 397 of configparser.py,

394:try:
395:    import ConfigParser
396:except ImportError:
397:    import configparser as ConfigParser

Looking at this page, it seems that Python 3.4 is loading the Python 2.7 environment, so compatibility is required. It was that. I hit the following command because the virtualenvwrapper may be out of date or missing.

sudo pip install -U virtualenvwrapper

wakana-no-MacBook-Pro:Documents wakanayoshizawa$ sudo pip install -U virtualenvwrapper

Enter the directory again and try loading .envrc.
