For some reason, I cannot pip install %CD%\*.whl as I will then get:
Requirement 'C:\\Users\fredrik\\Downloads\\*.whl' looks like a filename, but the file does not exist
`*.whl is not a valid wheel filename.
On macOS (and I believe on Linux), I can do this without issues:
pip install *.whl
Processing ./certifi-2017.11.5-py2.py3-none-any.whl
Processing ./chardet-3.0.4-py2.py3-none-any.whl
Processing ./idna-2.6-py2.py3-none-any.whl
Processing ./requests-2.18.4-py2.py3-none-any.whl
Processing ./urllib3-1.22-py2.py3-none-any.whl
...
Why is there a difference in this behavior between the platforms?
Is there a preferred way to make this (pip install *.whl) work on Windows?
If you know the package name e.g. foo
You can use this:
python -m pip install --find-links=C:\Users\fredrik\Downloads foo
this will find any foo package e.g. foo-X.Y.Z-cp37-cp37m-win_amd64.whl etc...
If you don't know the package name then you can try:
FOR %%i in (C:\Users\fredrik\Downloads\*.whl) DO python -m pip install %i

When you tell pip to install multiple packages simultaneously, it looks up all child dependencies and installs the most recent version that is allowed by all parent package restrictions.
For example, if packageA requires child>=0.9 and packageB requires child<=1.1, then pip will install child==1.1.
I'm trying to write a script to scan a requirements.txt and pin all unlisted child package versions.
One way to do this would be to simply install everything from a requirements.txt file via pip install -r requirements.txt, then parse the output of pip freeze, and strip out all the packages from my requirements.txt file. Everything left should be child packages and the highest version number that pip calculated.
However, this requires creating a Python virtual environment and installing all packages, which can take a bit a time. Is there any option in pip to do the version calculation without actually installing the packages? If not, is there pip-like tool that provides this?
You can read the package requirements for PyPI hosted packages with the json module:
python3 terminal/script:
import csv
import json
import requests
your_package = str('packageA')
pypi_url = 'https://pypi.python.org/pypi/' + your_package + '/json'
data = requests.get(pypi_url).json()
reqs = data['info']['requires_dist']
print(reqs)
print('Writing requirements for ' + your_package + ' to requirements.csv')
f = open('requirements.csv', 'w')
w = csv.writer(f, delimiter = ',')
w.writerows([x.split(',') for x in reqs])
f.close()
If i get your question correctly you’re trying to install a particular version of a package, one way to do this is after specifying the version in ur requirement.txt file, it can be installed by using pip install then the dependency plus the version
example pip install WhatsApp v3.5
I am getting following error while running this command on my virtual machine:
$ sudo pip install -U -v --no-deps -b /tmp/piyush/ /tmp/piyush/common_bundle
File "/usr/local/lib/python2.7/dist-packages/pip-6.0.6-py2.7.egg/pip/_vendor/pkg_resources/__init__.py", line 2807, in parse_requirements
raise ValueError("Missing distribution spec", line)
ValueError: ('Missing distribution spec', '/tmp/piyush/common_bundle')
My input file is an archive.
$ file common_bundle
common_bundle: Zip archive data, at least v2.0 to extract
The version of pip is:
$ pip -V
pip 6.0.6 from /usr/local/lib/python2.7/dist-packages/pip-6.0.6-py2.7.egg (python 2.7)
Here is the pip manifest present in the common_bundle:
# This is a pip bundle file, that contains many source packages
# that can be installed as a group. You can install this like:
# pip this_file.zip
# The rest of the file contains a list of all the packages included:
PyYAML==3.10
boto==2.6.0
msgpack-python==0.2.2
tornado==2.1.1
ujson==1.22
virtualenv==1.8.2
bottle==0.10.7
raven==2.0.3
protobuf==2.4.1
# These packages were installed to satisfy the above requirements:
simplejson==2.4.0
distribute==0.6.32
Does anything look fishy?
Thanks.
When pip installing from an archive, the file must either have the proper extension or you need to explicitly use the file:// protocol. Rename your file to /tmp/piyush/common_bundle.zip or use file:///tmp/piyush/common_bundle.
The error you're seeing has nothing to do with the contents of the archive, pip hasn't even unpacked it yet.
Check to see if there are any spaces in your path. This was my problem. Also try keeping the path to the file as short as possible.
I am just starting with virtualenv, but I am trying to install gevent within a virtualenv environment (I am running Windows). When I use PIP from virtualenv, I get this error:
MyEnv>pip install gevent
Downloading/unpacking gevent
Running setup.py egg_info for package gevent
Please provide path to libevent source with --libevent DIR
The package index has MSIs and EXEs for installing on Windows (http://pypi.python.org/pypi/gevent/0.13.7), but I don't know how to install those into a virtualenv environment (or if that is even possible). When I try pip install gevent-0.13.7.win32-py2.7.exe from the virtualenv promp, I get an error as well:
ValueError: ('Expected version spec in', 'D:\\Downloads\\gevent-0.13.7.win32-py2.7.exe', 'at', ':\\Downloads\\gevent-0.13.7.win32-py2.7.exe')
Does someone know how to do this?
Pip doesn't support installing binary packages, yet. If you want to install from binary package you have to use easy_install - easy_install gevent-0.13.7.win32-py2.7.exe

See Can I install Python windows packages into virtualenvs? Another option is to install from source and you can do this with pip but this requires setting up compiler and environment which is much harder than the simple command above.
From the error message, it would appear you need libevent source code. I would imagine you need to go a step further and compile/install libevent system-wide so pip can find it.
I would start by downloading the latest stable source from http://libevent.org/.
Compile and install it using instructions in the README: https://github.com/libevent/libevent#readme
To compile it on Windows, you'll need to use GNU-style build utilities like make and autoconf. I recommend http://www.mingw.org/.
Once you've installed libevent system-wide, I imagine pip will find it and proceed with gevent installation.
In the msi for gevent-0.13.7 there's an option to select an alternate installation point. point it to the root dir of your particular virtual environment (just above where /Lib and /Scripts are located). That should install it correctly.
You also need to make sure greenlets are installed. For that you can use Piotr's suggested method with easy_install on the .exe.
Since upgrading to subversion 1.7 I get "unrecognized .svn/entries format" when running buildout. I notice there is an unresolved bug reports for both distribute and setuptools for this error and it also seems that you can use setuptools_subversion to resolve the issue.
What I can't find out how to do is install setuptools_subversion so that buildout picks it up. Please can someone help?
I've tried
downloading it and running python setup.py install
adding it to the eggs list of the [buildout] part of my buildout configuration
You need to install it at the python site-packages level; easy_install (used under the hood by buildout) needs it available before it'll install anything else.
That said, the python setup.py install stanza should have installed it just fine; check by running the following test:
$ python -m setuptools_subversion
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/setuptools_subversion.py directory
That should print the installation path of the module, like it did for me in the above example. You could try to use pip or easy_install for automatic download:
$ pip install setuptools_subversion
or
$ easy_install setuptools_subversion
You can do that in a virtualenv if you want to isolate the installation. Because this is basically a dependency for svn 1.7, installing this at the same level as the svn binary (usually system wide) is certainly acceptable and the norm.
Note that the unrecognized .svn/entries format error message will not disappear, but your buildout will otherwise succeed. The message is printed no matter what as easy_install first tries the internal .svn parser before deferring to the external plugin.
If you really, really want to verify if the plugin is installed, run the following python code:
import pkg_resources
for entrypoint in pkg_resources.iter_entry_points('setuptools.file_finders'):
print entrypoint
On my system this prints:
svn = setuptools_subversion:listfiles
svn_cvs = setuptools.command.sdist:_default_revctrl
git = setuptools_git:gitlsfiles
hg = setuptools_hg:hg_file_finder
I'm trying to convert some date/times to UTC, which I thought would be dead simple in Python - batteries included, right? Well, it would be simple except that Python (2.6) doesn't include any tzinfo classes. No problem, a quick search turns up python-dateutil which should do exactly what I need.
The problem is that I need to install it on Windows. I was able to upack the .tar.gz2 distribution using 7-zip, but now I'm left with a collection of files and no guidance on how to proceed. When I try to run setup.py I get the error "No module named setuptools".
If dateutil is missing install it via:
pip install python-dateutil
Or on Ubuntu:
sudo apt-get install python-dateutil
Why didn't someone tell me I was being a total noob? All I had to do was copy the dateutil directory to someplace in my Python path, and it was good to go.
Looks like the setup.py uses easy_install (i.e. setuptools). Just install the setuptools package and you will be all set.
To install setuptools in Python 2.6, see the answer to this question.
Install from the "Unofficial Windows Binaries for Python Extension Packages"
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-dateutil
Pretty much has every package you would need.
It is a little tricky for people who is not used to command prompt. All you have
to do is open the directory where python is installed (C:\Python27 by default) and open the command prompt there (shift + right click and select open command window here) and then type :
python -m pip install python-dateutil
Hope that helps.
Using setup from distutils.core instead of setuptools in setup.py worked for me, too:
#from setuptools import setup
from distutils.core import setup
If you are offline and have untared the package, you can use command prompt.
Navigate to the untared folder and run:
python setup.py install
Just run command prompt as administrator and type this in.
easy_install python-dateutil
You could also change your PYTHONPATH:
$ python -c 'import dateutil'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named dateutil
$
$ PYTHONPATH="/usr/lib/python2.6/site-packages/python_dateutil-1.5-py2.6.egg":"${PYTHONPATH}"
$ export PYTHONPATH
$ python -c 'import dateutil'
$
Where /usr/lib/python2.6/site-packages/python_dateutil-1.5-py2.6.egg is the place dateutil was installed in my box (centos using sudo yum install python-dateutil15)
First confirm that you have in C:/python##/Lib/Site-packages/ a folder dateutil, perhaps you download it, you should already have pip,matplotlib, six##,,confirm you have installed dateutil by--- go to the cmd, cd /python, you should have a folder /Scripts. cd to Scripts, then type --pip install python-dateutil --
----This applies to windows 7 Ultimate 32bit, Python 3.4------
I followed several suggestions in this list without success. Finally got it installed on Windows using this method: I extracted the zip file and placed the folders under my python27 folder. In a DOS window, I navigated to the installed root folder from extracting the zip file (python-dateutil-2.6.0), then issued this command:
.\python setup.py install
Whammo-bammo it all worked.
