Twisted compilation failed in Ubuntu 14.04 - python

I am trying to install Crossbar in my ubuntu 14.04. I installed the
dependencies as per the instruction here. When I am trying to
install cross the twisted installation fails. I am having python
2.7.6. I installed all the python-devl packages and all are up to date. I am getting the below error when I execute "pip install
crossbar".

Do you have the dev files installed from pypy? I don't use Ubuntu, but I believe the package is called pypy-dev. I contains a proper Python.h.
The one you mention belongs to the main Python installation. /usr/include/python2.7/Python.h

You can install them using the following command.
Windows Subsystem for Linux / Debian / Ubuntu
sudo apt-get install python-dev
Fedora / RedHat / CentOS
sudo yum install python-devel
You need to install the python-dev package, which includes Python.h.
There is a much simpler solution, though - install Python for Windows, without using the Linux Subsystem. Starting with Python 3.5 pip sometimes (actually, quite often) installs the precompiled binary version, saving you a lot of trouble.
In fact, since Python 3.5, it's easier to install most packages on Windows than it is on Linux.
It's because of you didn't have python-dev or python3-dev packages due to your python version.
Just install them through 'pip' or 'pip3' package installer and enjoy it!
Note if you find the mentioned packages is installed and your problem is still exist!, you must look for 'Python.h' file in your file system by:
sudo find / -name "Python.h"
and then add listed paths which includes Python.h into your C_INCLUDE_PATH environment variable something like:
export C_INCLUDE_PATH=/usr/include/python3.6m/
and now retry your installation and enjoy!

I checked that Xcode should be properly installed and working
You should be using pip. Try:
pip install biopython
Uninstalled Canopy and everything worked like a charm...
Try installing the Biopython version available from the Canopy "Package Manager" > "Available Packages" > "Canopy Packages".
This way, I seem to have solved a similar problem while installing Pyensembl, that also installs Biopython.

Error during PyCUDA installation

I tried to install PyCUDA using these instructions: http://wiki.tiker.net/PyCuda/Installation/Linux

What should I do?
EDIT: My OS is: Arch Linux 3.3.2.1. GPU: Nvidia GF 9600M GS
Instead of su -c "make install" try sudo su - (to become root), and then, as root: make install (after navigating to the right directory)
This one full command worked for me:

Mysql for Python compiler MinGW32 gcc.exe error: CreateProcess file or directory not found

I'm trying to get Django/Python to work with MySQL, so I'm installing Mysql for Python adapter.
At one point, I discovered that I needed to use the MinGW compiler, so I installed that.
I encountered many annoying problems, and I managed to get past them. This one, however, is especially torturing.
The error occurs when I attempt to execute the following command in command line for Windows:
setup.py install build --compiler=mingw32
Here is the error:

> **gcc: /Z1: No such file or directory<br> gcc: CreateProcess: No such file or directory<br> error: command 'gcc' failed with exit status 1**
Can any of you guys help me out?
This error is caused by /Zl parameter, as they are special parameters used only by VC. We could delete them on setup_window.py.
Since you're talking about MinGW, I'm assuming you're building on Windows. You probably need to add the directory where mingw's gcc binary resides to your PATH.
Assuming it's C:\MinGW32, then you'd do something like:
set PATH=C:\MinGW32\bin;%PATH%
You'd do that before you ran python setup.py install build --compiler=mingw32
Using compiled binaries for windows machine helps. you can get it here http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/

Error building 'lxml.etree' extension

I'm trying to install lxml, on an Ubuntu server running Python 2.6 (in a virtualenv - the system Python is 2.5).
I've checked out via svn and as a result I've also install Cython, as per the instructions.
However, I get the following error when running python setup.py build:

And very similar errors if i try python setup.py bdist_egg, python setup.py build_ext -i or make
Trying to install via easy_install or pip produces the same error - although the former just hangs indefinitely.
As far as I am aware, all of the various dependencies, such as python-dev are installed.
What am I missing / doing wrong?
"I've checked out via svn" ...
"Building lxml version 2.3.alpha1-76211" ...
You appear to be on the bleeding edge. Suggestions: Use a released version of the lxml source. Consult with the lxml author/maintainer.
