I've been using Ubuntu 17.04 but my pip install is not working. Pip3 works fine and I've been getting by using python3 but I want to use volatility plugins with vol.py and I need python2 for that.
pip install just runs normally and installs everything fine but when I import it it says it's not installed. And yes I've tried using pip2, python -m pip, etc-- python -m pip just gives some error about no zlib when I've already installed it (zlib package thing). Help?
You can specify which version of python you want to use
Try this
python3.6 -m pip install <package>
or
python3 -m pip install <package>

We have installed python 3.9 from external Link, my OS has in built python 3.6 and python3-pip for 3.6 version. If I install pip packages it will install for python 3.6 and it is not compatible for python 3.9. How to install pip3.9 ? so that i will install packages from pip3.9 command.
OS: Cent OS
I tried like this
python3.9 -m pip
python3.9: No module named pip
Some Python distributions may not come with pip installed. Try
python3.9 -m ensurepip
to install pip for your interpreter first.
Adding on #Selcuk 's answer, you can define which python version runs pip:
For example:
/path/to/python3.9/python -m pip install mypackage
This would install mypackage for the python version you referenced to.
Another suggestion is to use Conda, which handles different python versions pretty effectively.
On Ubuntu 10.04 by default Python 2.6 is installed, then I have installed Python 2.7. How can I use pip install to install packages for Python 2.7.
For example:
pip install beautifulsoup4
by default installs BeautifulSoup for Python 2.6
When I do:
import bs4
in Python 2.6 it works, but in Python 2.7 it says:
No module named bs4
Alternatively, since pip itself is written in python, you can just call it with the python version you want to install the package for:
python2.7 -m pip install foo
Use a version of pip installed against the Python instance you want to install new packages to.
In many distributions, there may be separate python2.6-pip and python2.7-pip packages, invoked with binary names such as pip-2.6 and pip-2.7. If pip is not packaged in your distribution for the desired target, you might look for a setuptools or easyinstall package, or use virtualenv (which will always include pip in a generated environment).
pip's website includes installation instructions, if you can't find anything within your distribution.
You can execute pip module for a specific python version using the corresponding python:
Python 2.6:
python2.6 -m pip install beautifulsoup4
Python 2.7
python2.7 -m pip install beautifulsoup4
In Windows, you can execute the pip module by mentioning the python version ( You need to ensure that the launcher is on your path )
py -2 -m pip install pyfora
You can use this syntax
python_version -m pip install your_package
For example. If you're running python3.5, you named it as "python3", and want to install numpy package
python3 -m pip install numpy
Have tried this on a Windows machine and it works
If you wanna install opencv for python version 3.7, heres how you do it!
py -3.7 -m pip install opencv-python
Alternatively, if you want to install specific version of the package with the specific version of python, this is the way
sudo python2.7 -m pip install pyudev=0.16
if the "=" doesnt work, use ==
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev=0.16
Invalid requirement: 'pyudev=0.16'
= is not a valid operator. Did you mean == ?
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev==0.16
works fine
If you have both 2.7 and 3.x versions of python installed, then just rename the python exe file of python 3.x version to something like - "python.exe" to "python3.exe". Now you can use pip for both versions individually. If you normally type "pip install " it will consider the 2.7 version by default. If you want to install it on the 3.x version you need to call the command as "python3 -m pip install ".
Python 2
sudo pip2 install johnbonjovi
Python 3
sudo pip3 install johnbonjovi
For Python 3
sudo apt-get install python3-pip
sudo pip3 install beautifulsoup4
For Python 2
sudo apt-get install python2-pip
sudo pip2 install beautifulsoup4
On Debian/Ubuntu, pip is the command to use when installing packages
for Python 2, while pip3 is the command to use when installing
packages for Python 3.
for python2 use:
py -2 -m pip install beautifulsoup4
I faced a similar problem with another package called Twisted. I wanted to install it for Python 2.7, but it only got installed for Python 2.6 (system's default version).
Making a simple change worked for me.
When adding Python 2.7's path to your $PATH variable, append it to the front like this: PATH=/usr/local/bin:$PATH, so that the system uses that version.
If you face more problems, you can follow this blog post which helped me - https://github.com/h2oai/h2o-2/wiki/installing-python-2.7-on-centos-6.3.-follow-this-sequence-exactly-for-centos-machine-only
As with any other python script, you may specify the python installation you'd like to run it with. You may put this in your shell profile to save the alias. The $1 refers to the first argument you pass to the script.
# PYTHON3 PIP INSTALL V2
alias pip_install3="python3 -m $(which pip) install $1"
I'm using Ubuntu 22.04, which comes with python 3.10.4.
Some packages do not have recent pip packages, so I needed install from an older pip. This sequence worked for me.
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.9
sudo apt install python3.9-distutils
python3.9 -m pip install onnxruntime-gpu
Folder location: /usr/local/lib/python3.8
Package: python3.8 -m pip install <package_name>
I had Python 2.7 installed via chocolatey on Windows and found pip2.7.exe in C:\tools\python2\Scripts.
Using this executable instead of the pip command installed the correct module for me (requests for Python 2.7).
I think the best practice here is not to use the system python or install any system python package (no apt install). That is just the way to trouble.
Instead, build the required Python version from source, get it installed in /usr/local/... . Then use pip to install packages for that. It is really not that hard to build Python from source on Ubuntu.
sudo apt install build-essential
download the source from https://www.python.org/downloads/source/
unpack the file downloaded: tar xf <filename>
cd <directory> - change into the directory created.
./configure
make
sudo make install
Then check /usr/local/bin for a pip script tied to that version. Use that to pip install whatever you need. Also find the particular executable for the python version in that directory. You might have to shuffle things a bit if you get lots of versions.
Again, do not mess with system python.
I installed python3 from the official website and then installed jupyter notebook. While trying to run jupyter notebook, I was getting a "command not found" error.
I found this github issue and followed the instructions to delete python3 and reinstall using Homebrew instead (I've used Homebrew before).
When trying python3 -m pip install --upgrade pip i get a "No module named pip" error. My /usr/local/bin/ file shows pip, pip2, pip2.7, pip3, pip3.6.
I have a feeling my pip is not associated with the python3 that I installed using Homebrew. How can I fix this?
This way is a pretty fool-proof way to install pip for a specific python interpreter, when you have a big mess of them on the machine:
$ curl https://bootstrap.pypa.io/get-pip.py > /tmp/get_pip.py
$ my_python_interpreter /tmp/get_pip.py
Then:
$ my_python_interpreter -m pip install some_dist
I'm on Ubuntu and I have python2.7, (it came pre-installed) python3.4, (used before today) and python3.5, which I upgraded to today, installed in parallel. They all work fine on their own.
However, I want to use pip to install some packages, and I can't figure out how to do this for my 3.5 installation because pip installs for 2.7 and pip3 installs python 3.4 packages.
For instance, I have asyncio installed on 3.4, but I can't import it from 3.5. When I do pip3 install aysncio, it tells me the requirement is already satisfied.
I'm a bit of a newbie, but I did some snooping around install directories and couldn't find anything and I've googled to no avail.
I suppose you can run pip through Python until this is sorted out. (https://docs.python.org/dev/installing/)
A quick googling seems to indicate that this is indeed a bug. Try this and report back:
python3.4 -m pip --version
python3.5 -m pip --version
If they report different versions then I guess you're good to go. Just run python3.5 -m pip install package instead of pip3 install package to install 3.5 packages.
Another way would be to setup a virtual environment:
$ python3.4 -m venv envdir
$ source envdir/bin/activate
$ pip --version
Obviously, this won't install the packages globally and you'll have to source venv/bin/activate every time you wan to make use of it.
