How do I install Pip for Python 3.8 ? I made 3.8 my default Python version.
sudo apt install python3.8-pip
gives
unable to locate package python3.8-pip
and running
python3.8 -m pip install [package]
gives
no module named pip
I can't run sudo apt install python3-pip because it installs pip for Python 3.6
Install pip the official way:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3.8 get-pip.py
made 3.8 my default Python version
It depends on how you did that, but it might break something in your OS. For example some packages on Ubuntu 18.04 might depend on python being python2.7 or python3 being python3.6 with some pip packages preinstalled.
sudo apt install python3.8
sudo apt install python3.8-distutils
wget https://bootstrap.pypa.io/get-pip.py
sudo python3.8 get-pip.py
If you installed Python3.8 using apt, the pip documentation advises against using the get-pip.py script:
Be cautious if you are using a Python install that is managed by your operating system or another package manager. get-pip.py does not coordinate with those tools, and may leave your system in an inconsistent state.
The same page suggests running:
python3.8 -m pip --version
to determine if pip is already installed. I installed Python 3.8 on an Ubuntu18 machine using apt install python3.8, and I verified with the command above that it includes pip. It appears that Ubuntu package doesn't install a pip command that you can run directly. But you can run it using the python3.8 binary directly instead, anywhere you would have used pip:
python3.8 -m pip install [package]
you can try updating line #1 from /usr/bin/pip3 to #!/usr/bin/python3.8 as below
#!/usr/bin/python3.8
# GENERATED BY DEBIAN
import sys
# Run the main entry point, similarly to how setuptools does it, but because
# we didn't install the actual entry point from setup.py, don't use the
# pkg_resources API.
from pip import main
if __name__ == '__main__':
sys.exit(main())
What I used to install pip according to the current version of default python is:
sudo apt-get install python-pip
I am trying to install python paramiko using below command:
pip3 install paramiko
then I got an error:
The program 'pip3' is currently not installed. You can install it by typing:
sudo apt install python3-pip
then tried to install pip using above command, the result is:
Reading package lists... Done
Building dependency tree
Reading state information... Done
python3-pip is already the newest version (8.1.1-2ubuntu0.4).
The following packages were automatically installed and are no longer required:
python3-babel python3-dateutil python3-decorator python3-funcsigs python3-gevent python3-greenlet python3-html2text python3-mock python3-ofxparse python3-passlib python3-pbr python3-psutil
python3-psycopg2 python3-pydot python3-pyinotify python3-pypdf2 python3-serial python3-stdnum python3-tz python3-usb python3-vatnumber python3-werkzeug python3-yaml
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 82 not upgraded.
Then I tried to install paramiko again but getting the same error, pip is not installed.
When I type pip3 --version the output is:
The program 'pip3' is currently not installed. You can install it by typing:
sudo apt install python3-pip
pip --version
Output is:
pip 10.0.1 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
How can I resolve this?
For pip on python 3 you have to enter the following command:
sudo apt install python3-pip
Hope this helps
I usually do:
sudo python3 -m pip install paramiko
or
python3 -m pip --version
instead of
pip3 install
I don't know why but python -m pip etc ... works better than just pip etc... in my case.
if you really don't have pip (but I thought it comes automatically with python now) you can also get it using:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
(from here)
it works on my computer, I don't know why sudo apt-get would not work but you can try this solution instead.
This is on CentOs 6.6. I am trying to set up a scientific python environment. I want to avoid Anaconda. When trying to install matplotlib, I get "ImportError: No module named pkg_resources". Full install history:
sudo yum install gcc-c++.x86_64
sudo yum install gcc
sudo yum install atlas atlas-devel lapack-devel blas-devel
sudo yum install python-devel
sudo pip install numpy
sudo pip install scipy
sudo pip install pandas
sudo pip install matplotlib
At the last step, I get the message
Complete output from command python setup.py egg_info:
The required version of distribute (>=0.6.28) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using
'easy_install -U distribute'.
Then I do
sudo pip install --upgrade distribute
which installs distribute-0.7.3, setuptools-18.0.1. Then:
sudo pip install matplotlib
which results in:
File "/usr/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
Any ideas?
Update
After the above steps, setuptools and pip are broken in this installation. From a python shell, doing help() followed by modules does not list setuptools. A search in the filesystem for setuptools directories reveals:
/usr/lib/python2.6/site-packages/setuptools-18.0.1.dist-info/
while the setuptools.pth file in /usr/lib/python2.6/site-packages/ contains a pointer to the non-existent ./setuptools-0.6c11-py2.6.egg-info.
At the same time, there is a directory
/usr/share/doc/python-setuptools-0.6.10/
After all this, pip no longer works.
#pavan they said CentOS, so apt is unlikely to help them.
They could, though, do :
yum remove python-setuptools
yum install python-setuptools
(my also need to reinstall pip: yum install python-pip )
And that might fix the problem.
Try this for OS supporting apt-get (Ubuntu etc)
sudo apt-get install python-pkg-resources python-setuptools --reinstall
Try install python-pip (and dependencies):
yum install python-pip
This solved my problem (Centos release 6.8).
Just started Python a few days ago and I'm using PyCharm to develop a web application with Django. I have libpq-dev python-dev packages already installed, but it's still throwing me the same error:
./psycopg/psycopg.h:30:20: fatal error: Python.h: No such file or directory
which according to Google is the issue that occurs when python-dev package isn't installed. Note that I'm running the install from within the PyCharm interface for a virtualenv that I created for 3.2 and 3.3 (not sure how to run it from the terminal). Installing outside of the virtualenv still throws the same error, even when I install it from the terminal with setup.py. If I run pip install psycopg2 from the terminal, it succeeds, but it installs for Python 2.7. According to their website, they have support for up to Python 3.2.
On Ubuntu you just run this:
sudo apt-get install python3-psycopg2
Just run this using the terminal:
$ sudo apt-get install python3-dev
This way, you could use gcc to build the module you're trying to use.
Another option that seems to provide a newer version of psycopg2 than the one in the python3-psycopg2 package (at least when I wrote this):
sudo apt-get install pip3
sudo apt-get install libpq-dev
sudo pip3 install psycopg2
For most operating systems, the quickest way to install Psycopg is using the wheel package available on PyPI:
$ pip install psycopg2-binary
Check:
$ pip freeze | grep -i psycopg2
psycopg2-binary==2.9.3
This will install a pre-compiled binary version of the module which does not require the build or runtime prerequisites.
Or:
$ sudo apt-get install libpq-dev
$ pip install psycopg2
Check:
$ pip freeze | grep -i psycopg2
psycopg2==2.9.3
More info about psycopg vs psycopg-binary.
I have both python2.7 and python3.2 installed in Ubuntu 12.04.
The symbolic link python links to python2.7.
When I type:
sudo pip install package-name
It will default install python2 version of package-name.
Some package supports both python2 and python3.
How to install python3 version of package-name via pip?
Ubuntu 12.10+ and Fedora 13+ have a package called python3-pip which will install pip-3.2 (or pip-3.3, pip-3.4 or pip3 for newer versions) without needing this jumping through hoops.
I came across this and fixed this without needing the likes of wget or virtualenvs (assuming Ubuntu 12.04):
Install package python3-setuptools: run sudo aptitude install python3-setuptools, this will give you the command easy_install3.
Install pip using Python 3's setuptools: run sudo easy_install3 pip, this will give you the command pip-3.2 like kev's solution.
Install your PyPI packages: run sudo pip-3.2 install <package> (installing python packages into your base system requires root, of course).
…
Profit!
You may want to build a virtualenv of python3, then install packages of python3 after activating the virtualenv. So your system won't be messed up :)
This could be something like:
virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
pip install package-name
Short Answer
sudo apt-get install python3-pip
sudo pip3 install MODULE_NAME
Source: Shashank Bharadwaj's comment
Long Answer
The short answer applies only on newer systems. On some versions of Ubuntu the command is pip-3.2:
sudo pip-3.2 install MODULE_NAME
If it doesn't work, this method should work for any Linux distro and supported version:
sudo apt-get install curl
curl https://bootstrap.pypa.io/get-pip.py | sudo python3
sudo pip3 install MODULE_NAME
If you don't have curl, use wget. If you don't have sudo, switch to root. If pip3 symlink does not exists, check for something like pip-3.X
Much python packages require also the dev package, so install it too:
sudo apt-get install python3-dev
Sources:
python installing packages with pip
Pip latest install
Check also Tobu's answer if you want an even more upgraded version of Python.
I want to add that using a virtual environment is usually the preferred way to develop a python application, so #felixyan answer is probably the best in an ideal world. But if you really want to install that package globally, or if need to test / use it frequently without activating a virtual environment, I suppose installing it as a global package is the way to go.
Well, on ubuntu 13.10/14.04, things are a little different.
Install
$ sudo apt-get install python3-pip
Install packages
$ sudo pip3 install packagename
NOT pip-3.3 install
The easiest way to install latest pip2/pip3 and corresponding packages:
curl https://bootstrap.pypa.io/get-pip.py | python2
pip2 install package-name
curl https://bootstrap.pypa.io/get-pip.py | python3
pip3 install package-name
Note: please run these commands as root
I had the same problem while trying to install pylab, and I have found this link
So what I have done to install pylab within Python 3 is:
python3 -m pip install SomePackage
It has worked properly, and as you can see in the link you can do this for every Python version you have, so I guess this solves your problem.
Old question, but none of the answers satisfies me. One of my systems is running Ubuntu 12.04 LTS and for some reason there's no package python3-pip or python-pip for Python 3. So here is what I've done (all commands were executed as root):
Install setuptools for Python3 in case you haven't.
apt-get install python3-setuptools
or
aptitude install python3-setuptools
With Python 2.4+ you can invoke easy_install with specific Python version by using python -m easy_install. So pip for Python 3 could be installed by:
python3 -m easy_install pip
That's it, you got pip for Python 3. Now just invoke pip with the specific version of Python to install package for Python 3. For example, with Python 3.2 installed on my system, I used:
pip-3.2 install [package]
If you have pip installed in both pythons, and both are in your path, just use:
$ pip-2.7 install PACKAGENAME
$ pip-3.2 install PACKAGENAME

This is a duplicate of question #2812520
If your system has python2 as default, use below command to install packages to python3
$ python3 -m pip install <package-name>
Easy enough:
sudo aptitude install python3-pip
pip-3.2 install --user pkg
If you want Python 3.3, which isn't the default as of Ubuntu 12.10:
sudo aptitude install python3-pip python3.3
python3.3 -m pip.runner install --user pkg
You can alternatively just run pip3 install packagename instead of pip,
Firstly, you need to install pip for the Python 3 installation that you want. Then you run that pip to install packages for that Python version.
Since you have both pip and python 3 in /usr/bin, I assume they are both installed with a package manager of some sort. That package manager should also have a Python 3 pip. That's the one you should install.
Felix' recommendation of virtualenv is a good one. If you are only testing, or you are doing development, then you shouldn't install the package in the system python. Using virtualenv, or even building your own Pythons for development, is better in those cases.
But if you actually do want to install this package in the system python, installing pip for Python 3 is the way to go.
Although the question relates to Ubuntu, let me contribute by saying that I'm on Mac and my python command defaults to Python 2.7.5. I have Python 3 as well, accessible via python3, so knowing the pip package origin, I just downloaded it and issued sudo python3 setup.py install against it and, surely enough, only Python 3 has now this module inside its site packages. Hope this helps a wandering Mac-stranger.
Execute the pip binary directly.
First locate the version of PIP you want.
jon-mint python3.3 # whereis ip
ip: /bin/ip /sbin/ip /usr/share/man/man8/ip.8.gz /usr/share/man/man7/ip.7.gz
Then execute.
jon-mint python3.3 # pip3.3 install pexpect

Cleaning up...
You should install ALL dependencies:
sudo apt-get install build-essential python3-dev python3-setuptools python3-numpy python3-scipy libatlas-dev libatlas3gf-base
Install pip3(if you have installed, please look step 3):
sudo apt-get install python3-pip
Iinstall scikit-learn by pip3
pip3 install -U scikit-learn
Open your terminal and entry python3 environment, type import sklearn to check it.
To install pip for python3 use should use pip3 instead of pip.
To install python in ubuntu 18.08 bionic
before installing a version of python, activate virtual environment so that it won't have any problem in a future versions of python.
virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
then install the actual python version you want.
>> sudo apt-get install python3.7
To install the required pip package in ubuntu
>> sudo apt-get install python3-pip
You Can Simply type in terminal/console .
Commands
sudo apt update
sudo apt upgrade
sudo apt install python3-pip3
pip3 install package-name
Another way to install python3 is using wget. Below are the steps for installation.
wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz
tar xJf ./Python-3.3.5.tar.xz
cd ./Python-3.3.5
./configure --prefix=/opt/python3.3
make && sudo make install
Also,one can create an alias for the same using
echo 'alias py="/opt/python3.3/bin/python3.3"' >> ~/.bashrc
Now open a new terminal and type py and press Enter.
