python 2（而不是python 3）作为（临时）默认python？

您可以使用virtualenv

# Use this to create your temporary python "install"# (Assuming that is the correct path to the python interpreter you want to use.)virtualenv -p /usr/bin/python2.7 --distribute temp-python# Type this command when you want to use your temporary python.# While you are using your temporary python you will also have access to a temporary pip,# which will keep all packages installed with it separate from your main python install.# A shorter version of this command would be ". temp-python/bin/activate"source temp-python/bin/activate# When you no longer wish to use you temporary python typedeactivate
