我已经在我的系统上成功安装了 virtualenv 和 virtualenvwrapper。它工作得很好。为了将来的方便，我想创建一个脚本，将我最喜欢的所有模块安装到我命名为 pynumeric 的环境中，位于 ~/.virtualenvs 中。对于这个脚本，我需要在我的脚本中使用 virtualenvwrapper。不幸的是，这对我不起作用。我不断收到 workon 和 mkvirtualenv 不存在的错误。
所以基本上我的问题归结为:为什么 virtualenvwrapper 在终端中工作，而在我的 Python 脚本中不？
install_pynumeric.py(编辑)
#!/usr/bin/python
import os
import sys
import subprocess as sp
# Set CPU frequency governer to performance
#sp.check_call('cpuset gov performance', shell=True)
# Check for parent directory of virtual environments
if not os.path.isdir('/home/carlos/.virtualenvs'):
sys.exit('The parent directory for virtual environments does not exist yet. Create it before preceeding.')
# Create virtual environment pynumeric if it does not exist yet and activate
if not os.path.isdir('/home/carlos/.virtualenvs/pynumeric'):
sp.check_call('mkvirtualenv pynumeric', shell=True)
# Activate pynumeric
sp.check_call('workon pynumeric', shell=True)
# List of Python modules to be installed
modules = ['numpy',
'scipy',

'matplotlib',
'pyqt4',

'psutil',

]
# Install modules
for m in modules:
cmd = 'pip install ' + m
sp.check_call(cmd, shell=True)
# Deactivate pynumeric
sp.check_call('deactivate', shell=True)
# Set CPU frequency governer to ondemand
#sp.check_call('cpuset gov ondemand', shell=True)
我现在收到以下错误:
