I have one python package A which has depends on another private package named godot(hosted at bitbucket, and should be accessed by git+ssh protocol). In package A's setup.py, I have following code:
...
install_requires=['godot'],
dependency_links=['git+ssh://git#bitbucket.org/xxx/godot.git#egg=godot']
...
I have two questions here:
Now setuptools 1.4 (latest stable version) does not support 'git+ssh' protocol, only code in the development branch handle this protocol: Python setuptools: How can I list a private repository under install_requires?. I have installed the development version via:
pip install --upgrade --force-reinstall hg+https://bitbucket.org/pypa/setuptools#egg=setuptools
I almost solved this bit, but I wonder If any other approach available? Invoke pip install -r requirements.txt(have git+ssh://git#bitbucket.org/xxx/godot.git#egg=godot list in requirements.txt)?
The second question is name conflict. There is another package on pypi also named godot, So when I install package A using follow command, pip install the godot from pypi index:
pip install git+ssh://git#pypi.corp.com/xxx/A.git#egg=A
How could force pip(setup.py) to install the private godot package, rather than the one on pypi index?
For part 1: you can install packages via pip by specifying as:
$ pip install http://my.package.repo/SomePackage-1.0.4.zip
To keep it simple and avoid spending undue time on it, I would just download the .zip source file and install via pip as above.
See here...
For part 2: pip has a --no-dependencies switch. Add that after installing all the dependencies manually

I've a private pypi, and keep uploading new package framework to that registry.
I want to install the latest package in a virtualenv.
Command used:
pip install -i https://user:pass#registry framework
OUTPUT:
Collecting framework:
... downloads many versions
ERROR: Cannot install framework==0.25.13, framework==0.25.14 and framework==0.26.0 because these package versions have conflicting dependencies.
The conflict is caused by:
framework 0.26.0 depends on toolz<0.12.0 and >=0.11.1
framework 0.25.14 depends on toolz<0.12.0 and >=0.11.1
framework 0.25.13 depends on toolz<0.12.0 and >=0.11.1
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies
I want only the latest version to be downloaded. I cannot hard-code version like framework==0.26.0 while pip install because this command is to be used in script and I may need to modify the script everytime a new framework get uploaded.
pip version: pip 21.1.2
The solution that worked for this problem was using --extra-index-url instead of -i
Command to use
pip install --extra-index-url https://user:pass#registry framework
I'm deploying some custom packages with pip straight from my company's private git repo (and it's awesome). But what if I want to install a specific version of my package?
This question completements Specify extras_require with pip install -e.
I'm trying to install it with:
pip install git+https://github.com/user/project.git#egg=project==0.0.1[extra]
But I get a ERROR: Invalid requirement: 'project==0.0.1[extra]' message.
Thanks!
Easy enough:
pip install git+https://github.com/user/project.git#v0.0.1#egg=project[extra]
Of course, assuming version 0.0.1 exists.
If your project is in a subfolder:
pip install "git+https://github.com/user/project.git#v0.0.1#egg=project[extra]&subdirectory=my_subprojects/subproject"

I want to include a Python package dependency (installed using pip3 install) in an rpm package. I cannot install using dnf because its version is out of date. rpm returns the following error if I install the dependency using pip3 install:
error: Failed dependencies python3.6dist(dependency-package)
Any suggestions on how to include a Python package inside of an rpm?
OK. Some of your package require python3-somepackage or python3dist(somepackage). For rpm, it is just a string. Rpm does not care that the python module has been installed using pip. There must be some package which provides that string.
You have two options.
Prefered is use of pyp2rpm --srpm somepackage. That will download the latest version of the module from PyPI and produce the src.rpm. You can then build it using mock -r epel-8-x86_64 somepackage.src.rpm
The other option is to fake the provides. You can install the module using pip and then run: create-fake-rpm --build python3-somepackage 'python3dist(somepackage)'. This will generate the file fake-python3-somepackage-0-0.noarch.rpm which you can install using rpm. Then you can proceed with the install of your application. Be warned, that this is cheating. Future dnf upgrade will not update this module, you will have to take care of that yourself.
I am wondering about this command pip install -r requirements.txt. Does pip install modules if they are not satisfied or does it try and install anyway even if the modules are already there? If it is the latter, than is there any way to write a shell script which checks if dependencies are satisfied and if not invoke pip install?
Pip only installs packages that are not installed yet.
This does mean that even if a new version is available, old packages will be kept. You can pass the --upgrade flag to prevent that behavior and install the latest versions (but then pip will call pypi for every package in your requirements file, in order to identify its latest version).
An alternative is to have version specifiers in your requirements file (e.g. mypackage==1.2.3), so that if you change your requirements file and use new versions, pip will pick those up without the --upgrade flag.
Hi recently i installed setup tools module and google app engine gives me errors . Is there a way to uninstall setuptool? can any one tell me step by step because i tried hard
The answer depends on how it was installed.
If it was installed using the ubuntu (debian) package manager, try:
sudo apt-get remove --purge python-setuptools
[updated]
If you installed manually, probably the setuptools final location will be something like (adjust for your environment/python version):
/usr/local/lib/python2.6/dist-packages
Just delete the setuptools stuff there.
Lame, I know, but it is your burden for not using the excellent package manager provided by ubuntu: stick to dpkg unless you need bleeding edge stuff. For other python modules installed by setuptools, it provides no "uninstall" feature (but pip does, that is why there is a lot of enthusiasm around virtualenv, pip and yolk).
[2017 update]
It is 2017 and installing Python modules changed a bit:
pip is now the preferred installer program. Starting with Python 3.4, it is included by default with the Python binary installers.
venv is the standard tool for creating virtual environments (semi-isolated Python environments that allow packages to be installed for use by a particular application, rather than being installed system wide), and has been part of Python since Python 3.3. Starting with Python 3.4, it defaults to installing pip into all created virtual environments.
virtualenv is a third party alternative (and predecessor) to venv and if not official it is still very popular because it allows virtual environments to be used on versions of Python prior to 3.4, which either don’t provide venv at all, or aren’t able to automatically install pip into created environments.
easy_install pip
pip uninstall pip setuptools
(pip and setuptools both use the same package formats, but pip has uninstall support. kinda hilarious that installing something is the easiest way to uninstall.)
I was having trouble with the method below because my pip wasn't up to date.
easy_install pip
pip uninstall pip setuptools
After upgrading pip like this:
sudo -H pip install --upgrade pip
I was able to successfully uninstall setuptools like so:
pip uninstall setuptools
