Pandas installation fails with "OSError: [WinError8] Not enough storage is available to process this command"

I was trying to install pandas using this command:
python -m pip install pandas
Installation starts initially but then goes all red and returns this error:
Could not install packages due to an OSError: [WinError8] Not enough storage is available to process this command
--- Logging error ---
I don't think it's a memory issue because I checked usage and it was at a normal level.
I'm using Python 3.7 on Windows 7.
Any suggestions on how to fix it??

Eureka! I'm posting solution in case anyone encounters the same problem in the future.
After hours of trying a lot of different solutions I have finally succeed even though I still don't know what was the source of this problem.
To install pandas in case of facing error while downloading using pip command first download manually .whl files of pandas from PyPI website:
https://pypi.org/project/pandas/#files
Copy it to the folder that is used as your path in cmd console- don't change name of the file.
In cmd console use:
python -m pip install fullnameofthedownloadedfile.whl --no-deps
Use --no-deps as it's very likely that automatically downloaded dependencies will encounter similar errors during downloading as pandas- you will install them manually instead.
Once this is finished repeat process for numpy and dateutil and any other packages that might be required.
What a relief!!! Happy coding;)

error when downloading the gensim package in python

I have been trying to install the gensim package in python using pip, using the pip.main(['install','gensim']). It works and starts downloading, but then I get the following error:
THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.
gensim from https://files.pythonhosted.org/packages/82/f2/c2f2c87ed72483fce010fbfea1a3adbd168c0f0dafc878cbfb5a76381b03/gensim-3.4.0-cp36-cp36m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl#sha256=7bafe3f2fd49738942ef04396cb1e50a38283fe02203e5d4c66588daa01fb87c:

Any help would be appreciated

It seems like the package pip is trying to download and install is being modified in transit. You should be able to download, verify, and install the package yourself.
Download the package:
$ curl -O https://files.pythonhosted.org/packages/82/f2/c2f2c87ed72483fce010fbfea1a3adbd168c0f0dafc878cbfb5a76381b03/gensim-3.4.0-cp36-cp36m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl
Calculate the SHA256 sum to ensure the package has not been modifed:
$ openssl sha256 gensim-3.4.0-cp36-cp36m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl
The output should be 7bafe3f2fd49738942ef04396cb1e50a38283fe02203e5d4c66588daa01fb87c (according to https://pypi.org/project/gensim/#files)
Install the package:
$ pip install gensim-3.4.0-cp36-cp36m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl

I didn't solve the problem but I found a way to work around this challenge. I started using anaconda directly. I used the navigator to install gensim in my environments, then I used the spyder command prompt to run my codes.

Where did my python module install to?

I'm running python 3.6 via anaconda 3, using Visual Studio Code.
I followed instructions like these (Interactive Brokers API install) and downloaded the package to a local directory of mine say: c:\dev\pyib, so now the code is in c:\dev\pyib\IbPy-master
I open that directory in command line and run
python setup.py install
All runs ok.
But then my program, which is in c:\dev\pyib says Module not found. (In my case ibapi). The linter is also showing red.
There is no other python installed on this pc.
Where did the package install to? and how do I check that? What will I find where the package installed itself to that shows me its there?
Or do I have to use a trial-and-error with the linter and sys.path.append()? (I tried that with the directory where the files are downloaded to - to no avail)
I'm trying to set up the PYTHONPATH using the "env" in launch.json from Visual Studio Code, as shown in this unaccepted answer.
Current sys.path:
'c:\\dev\\pyIb',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\python36.zip',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\DLLs',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-
packages',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Babel-2.5.0-py3.6.egg',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32\\lib',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Pythonwin'
I deleted the ib directory and re-ran the install. The last line says: Writing C:\Users\user\AppData\Local\Continuum\anaconda3\Lib\site-pac‌​kages\IbPy2-0.8.0-py‌​3.6.egg-info So is the location of the egg-info the location of my undetected module? The actual folder in the site-packages is called ib.
Or could my problems be because of a difference in Lib vs. lib with the lowercase in the sys.path and the uppercase in the actual directory?
But the real question here is still: HOW DO I KNOW WHERE the package was installed what should I search for?

This answer is specific for anaconda3 Python and packages installed using python setup.py install (which is actually using distutils)
Take a look at anaconda3\Lib\site-packages you should see a directory for the package you installed.
The way to know for sure where your package is, is by doing a pip list then trying to pip uninstall and re-install again using the python setup.py install: Here are the detailed instructions:
When uninstalling, pip will tell you it cannot because it was done via distutils.
You'll get a message like this:
DEPRECATION: Uninstalling a distutils installed project (ibpy2) has been deprecated and will be removed in a future version.
This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
You'll be prompted to continue anyway. If you choose No, then you can find the directory in
C:\Users\<yourusername>\AppData\Local\Continuum\anaconda3\Lib\site-packages
Thanks to Emanuel Mtali for pointing me in the right direction
Some more information:
The problem I had was due to a stupid mistake of mine. I was running setup of a different (but related) package not used anymore. IbPy2 instead of TwsAPI. I was supposed to run the setup.py of the package installed via the latest version of the MSI from IB, and NOT the IbPy2 package. :-(

Python pip install gives “Command ”python setup.py egg_info“ failed with error code 1”

Edit: Yes I know this question already exists, except my question is a bit different and none of the solutions fixed it.
I do most of my Python stuff when I'm at work and not on my personal machine, but I decided to install it on my personal computer as well. I fresh installed python 3.6.1, and created a virtual environment with virtualenv. Then within the virtualenv I tried to pip install urllib (or any module) and I received the error:
(pdbot) C:\Users\user\Documents\pdbot>pip install urllib
Collecting urllib
Using cached urllib-1.21.1.tar.gz
Complete output from command python setup.py egg_info:

SyntaxError: invalid token
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\user\AppData\Local\Temp\pip-build-50tn0wlb\urllib\
I read elsewhere that this error had something to do with setuptools not being properly installed. So I ran this to attempt to fix the issue:
easy_install -U setuptools
I ended up receiving an even weirder error next:
(pdbot) C:\Users\zeke\Documents\pdbot>easy_install -U setuptools

This looks like a permissions error, but I ran these both in an administrator command prompt (Windows 10) and got the same result. I am the only user on this computer and I have all admin permissions. Is this virtualenv causing an issue? How do I remedy it?
EDIT: I was able to fix the permissions issue by leveraging the python executable like so:
python -m easy_install -U setuptools
But it didn't fix the python setup.py egg_info issue. I still get this error message when trying to pip install anything:
Command "python setup.py egg_info" failed with error code 1 in C:\Users\user\AppData\Local\Temp\pip-build-50tn0wlb\urllib\
I have tried both python -m pip install urllib and pip install urllib and neither work.

I had the same problem when trying to install urllib, but after doing a pip search urllib, I discovered that the problem was due to the version of urllib. From the search:
$ pip search urllib
...
> urllib5 (5.0.0) - Just increment the number and create a new lib. Never fix the original one.
At the end, a simple
pip install urllib5
within an elevated shell solved it.

Your problem has to do with permissions. The related/similar tools setup_tools, easy_install, and pip all tend to set a default set of permissions on files and folders they try to create in the package installation folder(s), rather than trying to match access permissions of the location they're installing in.
On Linux systems, where files and folders individually have permissions, this is frequently bypassed with the sudo command. On Windows, the equivalent is to run the installer as an Administrator. Since you're in the console, you have to open a console with Administrator privileges to run the pip command in.
Notable under Windows, the modules installed with pip from an Administrator console are still accessible to all users of the system that have the proper path in the PYTHONPATH system environment variable. Under Linux however, the problem is exacerbated by the fact that the files themselves may not be created with read and execute access for other users and may need to have their permissions manually modified after installation.
WARNING: urllib vs urllib2 vs urllibx
Both other answers claim that the problem is you're not specifying the correct "version" of the module in the call to pip. Neither is correct, as the error clearly indicates an installation folder access permissions violation causing the failure, but they also incorrectly recommended VERY unsafe behavior.
pip install urllib != pip install urllib5 these are two completely different packages.
The documentation for pip (https://packaging.python.org/tutorials/installing-packages/#id17) clearly says the way to specify a module version explicitly is pip install 'urllib==5'.
As part of how the package management engine implemented by pip works, running the command pip install urllib will always try to use the latest version of the urllib package, so you shouldn't need to specify the version unless you have some reason that you need a very specific version of the module.

There are two points to make in order to answer your question:
1. You are lucky you did not install that package!
The package you were trying to install was a maliciously created python package that was designed to look like a real package (in this case urllib3). If you had installed it, the package would have operated as normal except it would have sent some basic information about the system on which you installed the package to a URL (you can see more details on this here). You can read more about this fake package at either of the following links:
https://app.threatconnect.com/auth/incident/incident.xhtml?incident=5256822&owner=Common%20Community (you can sign up for a free account to view this one)
http://www.nbu.gov.sk/skcsirt-sa-20170909-pypi/index.html
Sending basic information about your systems to an unknown source isn't the worst thing you could do, but is certainly something you want to avoid when possible.
2. To properly install a package...
Specifically urllib:
To install urllib, you need to specify the version of the package you would like to install. For example, pip install urllib3.
Any package in general:
As #Elisabete Coelho suggested, you can use the pip search <package-name> feature to view the available packages. This is not perfect, however, as it may list malicious libraries like the one you were trying to install. A good guideline is that you should follow the installation instructions in a package's documentation closely to avoid any unforeseen issues. This is just an unfortunate necessity of living in a world where people make pretend python packages.

os 10.11.6 pip install permission error

I am a CS beginner taking udemy python course and trying to install pip in order to use matplotlib, pandas and so on in pylab.
I use IDLE 3.4.2 and latest version Pycharm
Tried
1. "pip installed pylab"(version not satisfies the requirement pylab,no matching distribution found for pylab);
2.same result with sudo before the first one;
3.sudo easy_install matplotlib（succeeded in terminal, but still no matplotlib module in shell) ;
4.brew install python 3(succeeded , but still no matplotlib module in shell, and every command looks like still for 2.7)
5.Anaconda Package based on preinstalling Macports (same result as 3)
6.On cloud9.io, still can't import matplotlib
Then tried to uninstall both 2 and 3 python then install
7.brew rm -rf/Library/Frameworks/Python.framework/Versions/2.7
(error:no keg argument)
Downloaded Xcode but "block compressed payload operation failed"

Answer in detailed direction will be appreciated as I am just a beginner having tons of stuff to learn from you.
Really frustrated by now.
