In developing a Django application, I used the following command to install MySQL (python3):
(Venv)$ pip3 install mysql-connector-python --allow-external mysql-connector-python
The installation was sucessful, and pip3 freeze > requirements.txt shows that mysql-connector-python==2.0.1 was installed.
However, in the production environment, pip3 install -r requirements.txt produced the following error message.
Downloading/unpacking mysql-connector-python==2.0.1 (from -r requirements.txt (line 6))
Could not find any downloads that satisfy the requirement mysql-connector-python==2.0.1 (from -r requirements.txt (line 6))
Is this a bug?
There is an outstanding bug with the way it is packaged on PIP.
here are the details: http://bugs.mysql.com/bug.php?id=76063
You can use following commands to install mysql-connector as mentioned on same link :
wget https://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-2.0.3.zip
unzip mysql-connector-python-2.0.3.zip
cd mysql-connector-python-2.0.3
python setup.py install
pip can not install mysql-python-connector due to an error on the part of its package maintainers. Here is the relevant issue filed against that package's bug tracker. Although technically it should be installable with
pip install --allow-external mysql-connector-python --allow-unverified mysql-connector-python mysql-connector-python
this does not work if the package maintainers fail to correctly register the external URLs to PyPI.
Note that PyMySQL appears to be a complete drop-in replacement, as a pure-Python MySQL driver that implements the Python DB API 2.0 specification. Additionally, PyMySQL appears to be actively maintained, uploaded to PyPI (as opposed to hosted on external URLs), and is under the more generous MIT license (as opposed to the GPLv2 license).
Try this if you do not want to install manually:
sudo pip3 install --extra-index-url https://pypi.python.org/pypi/mysql-connector-python/2.0.4 mysql-connector-python
Works for me on Debian Jessie.

Trying to pip install a repo's specific branch. Google tells me to
pip install https://github.com/user/repo.git#branch
The branch's name is issue/34/oscar-0.6 so I did pip install https://github.com/tangentlabs/django-oscar-paypal.git#/issue/34/oscar-0.6 but its returning a 404.
How do I install this branch?
Prepend the url prefix git+ (See VCS Support):
pip install git+https://github.com/tangentlabs/django-oscar-paypal.git#issue/34/oscar-0.6
And specify the branch name without the leading /.
Using pip with git+ to clone a repository can be extremely slow (test with https://github.com/django/django#stable/1.6.x for example, it will take a few minutes). The fastest thing I've found, which works with GitHub and BitBucket, is:
pip install https://github.com/user/repository/archive/branch.zip
which becomes for Django master:
pip install https://github.com/django/django/archive/master.zip
for Django stable/1.7.x:
pip install https://github.com/django/django/archive/stable/1.7.x.zip
With BitBucket it's about the same predictable pattern:
pip install https://bitbucket.org/izi/django-admin-tools/get/default.zip
Here, the master branch is generally named default.
This will make your requirements.txt installing much faster.
Some other answers mention variations required when placing the package to be installed into your requirements.txt. Note that with this archive syntax, the leading -e and trailing #egg=blah-blah are not required, and you can just simply paste the URL, so your requirements.txt looks like:
https://github.com/user/repository/archive/branch.zip
Instructions to install from private repo using ssh credentials:
$ pip install git+ssh://git#github.com/myuser/foo.git#my_version
To install a package from a subdirectory, say stackoverflow
$ pip install git+ssh://git#github.com/myuser/foo.git#my_version#subdirectory=stackoverflow
https://pip.pypa.io/en/stable/topics/vcs-support/
Just to add an extra, if you want to install it in your pip file it can be added like this:
-e git+https://github.com/tangentlabs/django-oscar-paypal.git#issue/34/oscar-0.6#egg=django-oscar-paypal
It will be saved as an egg though.
This worked like charm:
pip3 install git+https://github.com/deepak1725/fabric8-analytics-worker.git#develop
Where :
develop: Branch
fabric8-analytics-worker.git : Repo
deepak1725: user
You used the egg files install procedure.
This procedure supports installing over git, git+http, git+https, git+ssh, git+git and git+file. Some of these are mentioned in other answers.
It's good. You can use branches, tags, or hashes to install.
Steve_K noted it can be slow to install with "git+" and proposed installing via zip file:
pip install https://github.com/user/repository/archive/branch.zip
Alternatively, I suggest you may install using the .whl file if this exists.
pip install https://github.com/user/repository/archive/branch.whl
It's pretty new format, newer than egg files. It requires wheel and setuptools>=0.8 packages. You can find more in the documentation.
to me your suggestion from question work e.g.
pip install https://github.com/user/repo.git#branch
translating concretely to doing
pip install -U git+https://github.com/moskomule/anatome.git#dev
worked. Perhaps remove the extra / is redundant. My output:

I need to update offline a library in Python.
I have downloaded the library with pip download and then I try to update the library with the command:

which gives:

This behaviour can happen because pip by default works with system Python which is located in /usr/bin/ on Linux. When installing the package, by giving Python --user flag your package is installed in your user's version of Python, probably located somewhere in ~/.local/.
To solve the problem you can install the package to your system Python, which is generally not recommended without --user flag. Another option is to use virtual environments and have the distribution that is made specifically for your project. Currently the recommended way is using venv.
$ python -m venv env
$ source env/bin/activate
(env) $ pip install ... (packages you need to install without --user flag)
(env) $ pip freeze
# should give you the packages you installed
This can help you not only with this example, but it can always keep your system Python installation clean and if you mess something up, you will only mess the environment you are having for specific project.
I am trying to install waferslim (A python port of the fitnesse slim server and protocols) into my python environment. Waferslim is in the Python package library PyPI, however when I try to install it using pip it doesn't work, I get a package not found error:
(test) C:\Python27\VirtualEnvs\test\Scripts>pip install waferslim
Downloading/unpacking waferslim
Could not find any downloads that satisfy the requirement waferslim
Cleaning up...
No distributions at all found for waferslim
But if I try installing it with easy_install, it is installed correctly. Why does this happen? Is there a way I can install it using Pip instead of easy_install? I wrote a requirements.txt file that holds all the dependencies for my project, but running pip install -r requirements.txt fails because of waferslim.
I'n using pip 1.5.1 which worked fine up until today.
Now, I'm trying to install a requirements.txt in a fresh virtualenv, and for many packages it can no longer find specific old version for most packages.
$ pip install django-endless-pagination==1.1
Downloading/unpacking django-endless-pagination==1.1
Could not find a version that satisfies the requirement django-endless-pagination==1.1 (from versions: 2.0)
Some externally hosted files were ignored (use --allow-external to allow).
Cleaning up...
No distributions matching the version for django-endless-pagination==1.1
What do I need to do to get this to work again? Upgrading my app to use all the latest versions of all its packages is out of the question.
Update:
This works fine in pip 1.4.1. It's the newer version of pip that's causing it to fail.
From PIP 1.5 changelog:
BACKWARD INCOMPATIBLE
pip no longer will scrape insecure external urls by default nor will it install externally hosted files by
default. Users may opt into installing externally hosted or insecure
files or urls using --allow-external PROJECT and --allow-unverified
PROJECT
So in this case following ought to work the same way as old PIP:
pip install django-endless-pagination==1.1 \
--allow-all-external --allow-unverified django-endless-pagination
(There is no --allow-all-unverified, each unverified project name must be specified)
In case of using requirements.txt, it should be specified like this:
--allow-external django-endless-pagination
--allow-unverified django-endless-pagination
django-endless-pagination==1.1
In this case, you can use the URL of the appropriate zip file as input to pip install::
pip install https://github.com/frankban/django-endless-pagination/archive/v1.1.zip
Of course, not every package will have such a URL available, but most do.
I've occasionally used this to install the latest-greatest master, since in some cases the cheeseshop didn't have Python 3 ready packages yet.
Because the version on PyPI is 2.0 and pip now tries to honor the fact that maintainer wants you to use given version.
Trying to pip install a repo's specific branch. Google tells me to
pip install https://github.com/user/repo.git#branch

Prepend the url prefix git+ (See VCS Support):

which becomes for Django master:
pip install https://github.com/django/django/archive/master.zip
for Django stable/1.7.x:
pip install https://github.com/django/django/archive/stable/1.7.x.zip
With BitBucket it's about the same predictable pattern:
pip install https://bitbucket.org/izi/django-admin-tools/get/default.zip
Here, the master branch is generally named default.
This will make your requirements.txt installing much faster.
