Ubuntu Python "No module named paramiko"

Question

So I'm trying to use Paramiko on Ubuntu with Python 2.7, but import paramiko causes this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named paramiko

The other questions on this site don't help me since I'm new to Ubuntu.

Here are some important commands that I ran to check stuff:

sudo pip install paramiko
pip install paramiko
sudo apt-get install python-paramiko

Paramiko did "install". These are the only commands I used to "install" paramiko. I'm new to Ubuntu, so if I need to run more commands, lay them on me.

which python
/usr/local/bin/python

python -c "from pprint import pprint; import sys; pprint(sys.path);"
['',
 '/usr/local/lib/python27.zip',
 '/usr/local/lib/python2.7',
 '/usr/local/lib/python2.7/plat-linux2',
 '/usr/local/lib/python2.7/lib-tk',
 '/usr/local/lib/python2.7/lib-old',
 '/usr/local/lib/python2.7/lib-dynload',
 '/usr/local/lib/python2.7/site-packages']

In the python interpreter, I ran help("modules") and Paramiko is not in the list.

two paramiko folders are located in usr/local/lib/python2.7/dist-packages.

Short version: You're mixing Ubuntu's packaged version of Python (/usr/bin/python) and a locally built and installed version (/usr/local/bin/python).

Long version:

• You used apt-get install python-paramiko to install Ubuntu's official Paramiko package to /usr/lib/python2.7/dist-packages.
• You used (I assume) Ubuntu's version of pip, which installs to /usr/local/lib/python2.7/dist-packages. (See here.)
• You used a locally built version of Python, and because it's locally built, it uses /usr/local/lib/python2.7 instead of /usr/lib/python2.7, and because it doesn't have Debian/Ubuntu customizations, it doesn't check use dist-packages.

Solution: You should be able to add /usr/local/lib/python2.7/dist-packages to your /usr/local/bin/python's sys.path, but since you're using Ubuntu, it's easiest to let Ubuntu do the work for you:

• Use /usr/bin/python instead of a local version.
• Use Ubuntu's packages wherever possible (i.e., use apt-get instead of pip).
• Use virtualenv for the rest (to keep a clean separation between Ubuntu-packaged and personally installed modules).

I'd go so far as to uninstall the local version of Python and delete /usr/local/lib/python2.7, to ensure that no further mismatches occur. If you don't want to be that drastic, then you can edit your $PATH to put /usr/bin before /usr/local/bin to run the system version of Python by default.

There are two others methodes for add modules in python :

The first :

1. Download the package.
2. Create directory and paste the package in it.
3. Tap in the terminal :
4. export PYTHONPATH=$PYTHONPATH:path_of_package

The second :

4. open python interpreter:
5. import sys
6. sys.path.insert(0, "path_of_package")
