Q: Why did I get Permission denied after I used "sudo" keyword? 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
on my terminal, after I enter the password; the terminal says
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: '/Library/Python/2.7/site-packages/test-easy-install-2365.pth'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
/Library/Python/2.7/site-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.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.
For information on other options, you may wish to consult the
documentation at:
https://pythonhosted.org/setuptools/easy_install.html
Please make the appropriate changes for your system and try again.
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

A: 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
