Answer 1

I solved it. Since the pip version is 1.5.4 (you can confirm it by pip -V), upgrade pip is necessary. At the beginning, I can't upgrade pip with: pip install --upgrade pip. I used another way to upgrade pip (https://askubuntu.com/questions/775942/how-to-install-the-latest-version-of-pip-when-i-already-installed-the-provided-b):

wget https://pypi.python.org/packages/e7/a8/7556133689add8d1a54c0b14aeff0acb03c64707ce100ecd53934da1aa13/pip-8.1.2.tar.gz
tar -xzvf pip-8.1.2.tar.gz
cd pip-8.1.2
sudo python setup.py install

then upgrade to latest version of pip by: pip install --upgrade pip

then I can install jupyter by: sudo pip install jupyter.
