How to install downloaded Python packages without sudo?

I need to install https://pypi.python.org/pypi/PasteScript on a VM without sudo access (this one, if relevant). I've downloaded it but when I run python setup.py install I get:
running install Checking .pth file support in
/usr/local/lib/python2.7/dist-packages/ error: can't create or remove
files in install directory
The following error occurred while trying to add or remove files in
the installation directory:
[Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/test-easy-install-1621.pth'
The installation directory you specified (via --install-dir, --prefix,
or the distutils default setting) was:
/usr/local/lib/python2.7/dist-packages/
Perhaps your account does not have write access to this directory? If
the installation directory is a system-owned directory, you may need
to sign in as the administrator or "root" account.
One alternative suggestion I found was to use pip, but I can't install pip without sudo.
PS: There are many similar questions, but none (that I can find!

What about:
python setup.py install --user
As stated in the doc, it should work as you expect: https://docs.python.org/2/install/#alternate-installation-the-user-scheme

variable.

Running the "python" command in your terminal will by default run Python 2 on many systems, even after you have installed Python 3. Try using the "python3" command instead.

try this:
sudo python setup.py install

Anyone could help me?
Thank you very much~

You are trying to install the package to a system owned folder location. You can overcome this by running sudo python setup.py installm but you will end up with a mess of installed libraries. Rather create a virtual environment in a location that your user owns. This way you keep your main python install clean and can chop and change versions as you need.

I want to install NLTK(natural language toolkit) on my mac, but when I used
sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | python

Something went wrong during the installation.
See the error message above.
Could anyone please tell me how to fix it, I really need this toolkit to finish my work.
Thanks

You need a second sudo, you need to also run python with sudo python
sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python
