How to successfully enable SSL? Tried enabling SSL and TLS based on this link and restarting the Server, but no luck
Or at least, any work-around.
I'm not a developer and I reckon I'm not entirely qualified to explain exactly how this should be solved, but I've recently had the same issue and just spent most part of 2 days scouring the internet for a solution.
I have python3.6 and python2.7 installed so for me there is a slight juggling of order of environment variables needed. Easiest seems to be to keep the python2.7 env vars on top for installing
pip install virtualenv
and then the way I solved the SSL 403 Error was to witch the environment variables around again, putting python3 on above python2, so that pip installs with python3 and then download the actual virtualenvwrapper-powershell package [virtualenvwrapper-powershell-12.7.8.zip] from here:
https://pypi.python.org/pypi/virtualenvwrapper-powershell
Once you got that there are a few links I got information from:
https://bitbucket.org/guillermooo/virtualenvwrapper-powershell/issues/5/cant-install-package-with-python3-and-pip
and
https://bitbucket.org/guillermooo/virtualenvwrapper-powershell/issues/21/build-error-with-old-distribute
So using these two links, we're now installing envwrapper with python3 and getting another error: TOKEN_READ.
That's (was for me) solved by editing the distribute_python.py file in the zip you downloaded above by changing Line 50 assignment, by putting an 's' after the 'DEFAULT_URL = http'. Keep the rest of the URL in the quotes there, just make it an SSL address.
Next open the setup.py file in the same ZIP, and edit Line 76 by removing teh 'L' following the number following the TOKEN_READ variable.
This should take care of both the TOKEN_READ error which seems to have something to do with python3 and virtualenvwrapper, as well as the SSL error that we both seem to have experienced, which seem to have something to do with the version of the distribute file.
Once this is done you should be able to
pip install virtualenvwrapper-powershell
Restart powershell, and
Import-Module virtualenvwrapper
if you now get two other errors, the first one should be a Function:/TabExtension Error
That's solved by finding and editing the file that you see in the path in the error message and just adding a '2' after Function/TabExtension on Line 12 i think. Save and restart powershell. The other error if you have one is taken care of by creating your system environment variable for WORKON_HOME. Instructions here:
http://www.tylerbutler.com/2012/05/how-to-install-python-pip-and-virtualenv-on-windows-with-powershell/
and here:
https://rseshan.wordpress.com/2017/04/05/configuring-virtualenv-for-python-on-windows-10-using-powershell-wrapper/
As well as all this I also installed ez_setup.py from the tutorial linked to in your question. As well as after that force re-installing PIP by:
python -m pip install --upgrade --force-reinstall pip
But I have absolutely no clue if this is at all needed as it didn't help on its own, before I did the manual wrapper modifications described above.
Hope this helps! But this got it working for me, after hours of googling my heart out ;)
ADDON in regards to the comment below:
Of course the downloaded envwrapper ZIP file needs to be installed at the path where it sits on the drive after download, so rather than just doing pip install virtualenvwrapper-powershell it was in my case pip install C:\Users\*USER*\Downloads\virtualenvwrapper-powershell-12.7.8\virtualenvwrapper-powershell-12.7.8
Now another error that occurred, covered here
..is that virtualenvwrapper might install itself in a strange location which causes an Error when you try to use Import-Module virtualenvwrapper
In my case that was: C:\Program Files (x86)\Python27\Lib\site-packages\Users*USER*\Documents\WindowsPowerShell\Modules\VirtualEnvWrapper instead of C:\Users*USER*\Documents\WindowsPowerShell\Modules\VirtualEnvWrapper
I simply cut/pasted the Modules folder with everyting in it to the correct folder in the User/Documents folder where it can be found by the Powershell profile. I just thought I'd add this as I just went through all these steps again today.
Download the zip file:
https://files.pythonhosted.org/packages/f5/40/36d418b950139cd09738c0924066ef340ffd6c43f79f67c6152c56a8a628/virtualenvwrapper-powershell-12.7.8.zip
Unzip the file, open distribute_setup.py, and change DEFAULT_URL from http to https, rezip the file (to a fresh zip file).
pip install path_to_zipfile

I am trying to install jupyter notebook but for some reasons I am not able to install it. I have looked into several links like this and this but it did not help me. I am guessing the problem here is with the installation of pip. When I check the version of pip I get the following result :
shaloin#shaolin-Inspiron-3543:~$ pip --version
pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)
But when I try to upgrade the version of pip, I am getting this error :
shaloin#shaolin-Inspiron-3543:~$ sudo pip install --upgrade pip
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement pip in /usr/lib/python2.7/dist-packages

So, I searched for the error and I got to know that if you are behind proxy you should try out the following command :
sudo pip --proxy [NITS:abcde#]172.16.30.20:8080 install jupyter
where NITS is the usename abcde is the password , proxy server = 172.16.30.20 and password=8080, after which I got the following error :

I also tried setting up my proxy in this way :
set http_proxy=http://username:password#proxyAddress:port
set https_proxy=https://username:password#proxyAddress:port
but none of that works for installing jupyter notebook using pip.
Please don't mark this question as duplicate as because I have been searching for the solution for a long time and none of them works.
Can anyone please help??
For Ubuntu 14.04
I solved the problem of installation using anaconda. The description is given in this link.I couldn't fix the problem of upgrading pip. The steps for installing jupyter notebook is given below :
Step 1 (refer here)
First we install anaconda using wget
32 bits version
wget
https://3230d63b5fc54e62148e-c95ac804525aac4b6dba79b00b39d1d3.ssl.cf1.rackcdn.com/Anaconda-2.3.0-Linux-x86.sh
64 bits version
wget
https://3230d63b5fc54e62148e-c95ac804525aac4b6dba79b00b39d1d3.ssl.cf1.rackcdn.com/Anaconda-2.3.0-Linux-x86_64.sh
Step 2
After the download is over :
32 bits version
bash Anaconda-2.3.0-Linux-x86.sh
64 bits version
bash Anaconda-2.3.0-Linux-x86_64.sh
After downloading anaconda, open your terminal and type the following command :
$ sudo gedit ~/.profile
Add the given line at th end of the file :
export PATH=~/anaconda2/bin:$PATH
Step 3
After adding the line save the file. Open a new terminal and go to the directory where anaconda was downloaded.
$ cd anaconda2/bin
~/anaconda2/bin$ source activate
(root):~/anaconda2/bin$ jupyter notebook
The jupyter notebook will be opened in the browser.
For more information on jupyter notebook you can refer to this link.
Hy Everyone,
I try to install a script on my server using a terminal but due the installation I get an error. I will past here, the last lines of terminal.

Can someone help me to fix it ? Should install python develop ? If yes, how ? :D
As the error message is quite clear: httpagentparser is not installed https://pypi.python.org/pypi/httpagentparser
You should install it first, maybe it's available in the ubuntu software center. Else install via pip:
pip install httpagentparser
And if you don't know pip and/or have pip not installed. See https://pip.pypa.io/en/stable/installing/
I have trouble creating a virtualenv on a server that blocks all internet access. Has anybody successfully done that before? I searched but doesn't show up anything helpful. I have no problem transferring data back and forth, but I don't know what packages need to be downloaded and what options I need to have for the installation.
If you are curious what I got by trying to create one, here's the backtrace:

Thanks for any help.
If you update virtualenv to a version >= 1.10, then it will never connect to the internet regardless of any flag (see the "Changes & News" section here)
The internet connection is used to install the setuptools and pip packages in the virtual environment. Older versions of virtualenv will try to download these two packages, while newer versions ship with them and will just unpack them when necessary.
Since your virtualenv version (1.7.2) is lower than 1.10, you can use the --never-download flag in order to avoid connecting to the internet. Later on, you can install (offline) what you need.
Here (section "The --extra-search-dir Option") it's explained how to bootstrap setuptools and pip without an internet connection. You basically need to get the .egg files for these packages and put them somewhere local, and then you need to do:
$ virtualenv --extra-search-dir=/path/to/eggs --never-download ENV
mkdir .mypypi
pip install --download $HOME/.mypypi ipython ipdb django
Now transfer the contents from .mypypi to your server. Let's say you copied it to your $HOME Then do this:
pip install --no-index --find-links=file:/$HOME/.mypypi ipython
This should work for requirements.txt file too.
I am trying to build the HelloWorld example page from the Pyjamas example folder. However I am receiving this error when I run: sudo pyjsbuild helloworld.py. This error seems pretty universal to python as it seems to be related to the setup/configuration of my python environment. Any advice on where to look for the problem?
Here is the error

After trying the various answers, it turns out pip was not properly installing the six package, whatever that is. So I ran sudo easy_install pip (--upgrade) to make sure the script configuration was right. It wrote some extra files so I assume that's why my next command sudo pip install six or sudo pip install six --upgrade worked. Now I ran into another error -_-, For anyone looking later: Runtime Error: Top module not found 'hello world'
Edit: The top module error is coming from trying to build into the output folder that is not pyjs/. All I had to do was move the folder up to pyjs/ folder in sitepackages/.

dule named MySQLdb
First question is, why does Python not simply include this MySQLdb module?
OK, just fine, try to search to solve this message.
I have looked around stackoverflow.com for installing this module but did not have a good result.
Download this module at: http://sourceforge.net/projects/mysql-python/
Comes to the installation of this module on my Windows Vista system.
After the extraction of the package, I run the cmd prompt to continue with the installation:
$ python setup.py install
Again it showed me one other message:

Traceback (most recent call last):

Playing around with this error message, I know that there is the ez_setup.py within the package:
$python ez_setup.py
It seems that everything is OK:

Visual Studio 2003 was not found on this system. If you have Cygwin installed,

How can I fix this problem?
Did you try looking here: http://sourceforge.net/projects/mysql-python/files/
That is the download area of MySQLdb project, it has nothing to do with django, so your question is incorrect - django does not make switching database backends hard, you just change one line. And of course, your python installation should support that database first, so by downloading binary package for Windows from the link I gave above (chose correct version to match your version of python) you can avoid all the hassle of compiling the source release.
Most probably you need either MySQL-python-1.2.2.win32-py2.5.exe or MySQL-python-1.2.2.win32-py2.4.exe
Uh, this isn't Django, this is you downloading some unspecified Python environment and expecting it to magically do everything exactly the way you wanted it to. Find a good tutorial on this and follow the instructions.
BTW, this is a very helpful forum, but giving no specifics and then delivering a non-question with an attitude is not a good way to get people to feel helpful.
I once had the same problem running Python and MySQL on the same computer. Like the guys/gals said above, Python does not come with built-in support for MySQL, so you will need to download the connectors.
The link given above by #kibitzer will most likely not work on Windows successfully, so go here to download a copy of the connector that works with windows. It comes with installer and no need to run setup.py script manually.
