I'm very new in Python and need to install asyncmongo package for my environment. But when I
excuting pip install asyncmongo it fails with the following error.
C:\git\project>pip install asyncmongo
Downloading/unpacking asyncmongo
Could not find any downloads that satisfy the requirement asyncmongo
Some externally hosted files were ignored (use --allow-external asyncmongo to allow).
Cleaning up...
No distributions at all found for asyncmongo
Storing debug log for failure in C:\Users\Name\pip\pip.log
What I'm doing wrong?
I had the same issue just now (guessing that the library you're trying to install doesn't have a distribution up on the repository which pip is using). Instead, install the easy_install utility and do:
easy_install asyncmongo
Also, as a side note, I'd recommend using virtualenv and virtualenvwrapper which comes with pip/easy_install.
They segregate your python installs and it is basically like using a python install for every project you work on instead of sharing it globally. It includes both pip and easy_install which is useful because when I can't find something with pip or if the pip install fails, I'm usually able to find it with easy_install.
I found the solution. The problem was caused because of asyncmongo 1.2.2 sources was hasted on the amazon file server, so in that case pip should be invoked with additional flags (--allow-external packagename and --allow-unverified packagename) so to install it properly follwing command should be executed:
pip install --allow-external asyncmongo --allow-unverified asyncmongo asyncmongo
You are on Windows platform and pip is not as great for Windows as for Linux or Mac. easy_install has some some advantages on Windows, such as installing a precompiled .exe binary.
On a different note, you may consider using motor instead of asyncmongo. It is newer and looks more elegant.

I have a python library installed on my pc. I did it with pip install. Is it possible to create .whl file of that library with Python code?
I need it, because i don't have access to internet on that pc currently.
If I were you I would try some variant of python -m pip wheel --no-index --no-deps NameOfLibrary.
Otherwise maybe the wheel is already in one of pip's caches (build cache or download cache). You can find their location with python -m pip cache info and go from there.
I tried to install PyAudio on Windows 7 64bit.
Installing it with pip throws dependency errors which end up in the question how to satisfy those.
So i tried to install it with wheel, the suggestion was to just use pip install:
D:\Programming\Kivy>dir
...
27.03.2015 08:11 113.556 PyAudio.whl
D:\Programming\Kivy>pip install PyAudio.whl
Downloading/unpacking PyAudio.whl
Could not find any downloads that satisfy the requirement PyAudio.whl
No distributions at all found for PyAudio.whl
Storing complete log in C:\Users\WindowsPro\AppData\Roaming\pip\pip.log
Any suggestion how to install pyaudio?
What version of pip do you have? Show the output pip -V. It might be necessary to have a current pip version 6 to install the whl. If this is not the case do pip install --upgrade pip (it might be necessary to start the console with admin rights).
Did you download the library from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio? I just installed this version with pip and it works.
As an alternative you can download the installer exe from http://people.csail.mit.edu/hubert/pyaudio/#downloads and install it like a regular program.
If you cant donwload it by pip install pyaudio you can download it from here.
When you found PyAudio, find the version of your Python (ex. 3.7.2 32bit).
DOWNLOAD THE RIGHT VERSION. Once you found the .whl of your python version, download it. Install it by opening cmd, going to the folder that you save it and write pip install "pyaudio_whl_file.whl"
And that's it
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 want to try Ghost.py.
its documentation says that installation require PyQt or PySide.
I have installed pyqt4-dev-tools using command apt-get install pyqt4-dev-tools on my Kubuntu 13.10.
I am getting error
root#alok:~# pip install Ghost.py
Downloading/unpacking Ghost.py
Could not find a version that satisfies the requirement Ghost.py (from versions: 0.1a, 0.1a2, 0.1a3, 0.1b, 0.1b2, 0.1b3)
Cleaning up...
No distributions matching the version for Ghost.py
Storing complete log in /root/.pip/pip.log
I have installed PySide too still I am not able to install Ghost.py using pip install Ghost.py
using pip is so straight forward but I am not able to figure out what is wrong this time.
output of /root/.pip/pip.log is available at http://paste.ubuntu.com/7189458/
I had the same problem on OSX with PyQt installed via Homebrew.
Using pip install --pre Ghost.py made it work. This is also suggested in the pip.log you provide.
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.
