All the answers have so far only 'solved' the problem by installing the ldap and other development packages globally, which doesn't solve the problem of not being able to install the python-ldap package in the virtual environment.
Examples include:
How do I install python-ldap in a virtualenv on Ubuntu?
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
I am using ubuntu 14.04, python 2.7 and flask in my virtual environment.
When I run pip install python-ldap, I receive the following error.

If I try to pip install any of the suggested dev libraries so that they are inside my virtual environment, I get the following error.
Could not find a version that satisfies the requirement libsasl2-dev (from versions: ) No matching distribution found for libsasl2-dev
I can install all this stuff globally just fine, but that just plain defeats the purpose of using virtualenv.
I would really like to find a meaningful, virtualenv solution, since all I have been able to find is non-virtualenv solutions for a virtualenv question.
Thanks.
The Python package python-ldap requires some other libs (libsasl2-dev, …) which are not python libs (so you can't use pip to install them). So, to use them, you have to install them. Two solutions:
use your package manager to install them (ex.: apt-get) ;
download their source code and compile them locally (in your virtualenv) (useful for some libs in special cases).
Maybe you can try the second solution?

In order to install memsql-python you need to ensure that you have the dependencies already available. Specifically, the dependency that seems to be missing from your environment is libmysqlclient-dev or an equivalent package.
Note - you are overriding the include paths to point at your openssl installation which may be causing this issue due to how the compiler is searching for development headers.
According to the project's readme, use the following steps to get started quickly on Ubuntu:
sudo apt-get update
sudo apt-get install -y mysql-client python-dev libmysqlclient-dev python-pip
sudo pip install memsql
Use the following steps to get started with RHEL based distributions such as Amazon Linux or Centos:
sudo yum update
sudo yum install -y gcc mysql-devel
sudo pip install memsql
-- edit to address question regarding installation on Mac OSX
On a Mac it appears that you can install the mysql-client package from brew which in theory should provide the libmysqlclient-dev package. Once available try installing the memsql-python package without overriding linker flags since memsql-python should build fine without openssl. If you need openssl support then you will need to ensure that both the openssl and libmysqlclient-dev shared objects are available to the linker at compilation time.
This procedure worked for me:
brew remove mysql
brew install mysql#5.7
brew link --force mysql#5.7
I read a post and adjusted the procedure to link things in the /usr/local/bin instead of adding a new route to the PATH variable.

First you need to have pip installed. Then you can download the dlib python 2.7 version from "https://pypi.python.org/pypi/dlib/18.17.100" website where you will get wheel of dlib. And then use normal procedure like pip install 'path to dlib wheel'.
For ex. f you have saved .whl file to downloads folder then type pip install C:\Users\XYZ\Downloads\dlib-18.17.100-cp27-none-win32.whl.
This will surely work. When I tried I didn't get any error and dlib got successfully installed.
Cheers
The pip package might be broken or might not be updated. Anyway, download the dlib_master from :https://github.com/davisking/dlib.git
After that there is an easy guide for installation in python. Go to the folder containing setup.py and then open terminal or whatever and type
sudo python setup.py install.
When I sudo pip install pyquery, sudo pip install lxml, and sudo pip install cython, I get very similar output with the same error that says:

I ran into this problem when I attempted to upgrade my pandas version to 0.15.2
If you install gcc-4.9 you are likely to still have an older version of gcc on your system (gcc-4.7 in my case).
I can think of 3 ways to solve this issue:
a) symlink /usr/bin/x86_64-linux-gnu-gcc to
/usr/bin/x86_64-linux-gnu-gcc-4.9
if you want to be more organized about this use update-alternatives, see https://askubuntu.com/questions/26498/choose-gcc-and-g-version
b) figure out how to manually specify which compiler pip uses and set it in some sort of .conf file - I haven't examined where this file lives or if there are CLI options for pip that accomplish the equivalent. In principle, creating/editing a /usr/lib/pythonX.Y/distutils/distutils.cfg should do it. I ran into problems when I tried to use this approach.
c) Edit /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py to reflect your updated compiler
How to use MinGW's gcc compiler when installing Python package using Pip?
https://docs.python.org/2/install/#distutils-configuration-files
I went with the quick and dirty solution (a) to force everything to work
root#localhost:/home/user1$ rm /usr/bin/x86_64-linux-gnu-gcc
root#localhost:/home/user1$ ln -s /usr/bin/gcc-4.9 /usr/bin/x86_64-linux-gnu-gcc
root#localhost:/home/user1$ pip install pandas --upgrade
. . . pandas compiles with gcc-4.9 here . . .
move things back to how they were
root#localhost:/home/user1$ rm /usr/bin/x86_64-linux-gnu-gcc
root#localhost:/home/user1$ ln -s /usr/bin/gcc-4.7 /usr/bin/x86_64-linux-gnu-gcc
One possible solution would be to use GCC 4.9 or higher, which does support the -fstack-protector-strong flag.
Instead of upgrading to GCC 4.9, I was trying to find where the flag was defined and remove it. On Debian Wheezy, I found it in /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py which belongs to the libpython2.7-minimal package. My solution was to replace all occurrences of -fstack-protector-strong with -fstack-protector within this file. Then pip install executed the correct build command.
I am currently trying to install getch, a simple python package and have run into quite a bit of difficulty. I recently installed pypy in a kind of messy way (I wanted to get numpy with pypy working, which was a considerable pain) so that might have to do with the problem I'm having.
Okay, so I try to run
sudo pip install getch
and I get the error...
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
and as a bonus, a character encoding error.
This is the error that folks get when they don't have python-dev installed. However, I do. I attempted to work around this issue, by downloading the package and installing it manually.
sudo python setup.py install
also gave me the gcc error from above. I have gcc installed, and x86_64-linux-gnu-gcc works in terminal fine. I made a simple hello world program in c that simply includes Python.h. That worked fine as well. After remove --purging pypy, python, and python-dev from my system, I re-installed just python and python-dev and I still have the same silly issue.
Anyone have any thoughts?
Here's a pastebin of the exact error I'm getting. pastebin.com/mjRdADZx
You need to manually download the Python 2 version and install it. The version downloaded by pip is for Python 3.
The clue is this line:

The Python 2 version is also 1.0, but the file name is getch-1.0-python2.tar.gz. You can download it directly from the index.
Once downloaded, extract the archive and then python setup.py install from within the extracted directory.

any ideas ?
this is the interface for the ipopt library which is required to compile. as stated in the setup.py file
# You will probably have to edit this file in unpredictable ways
# if you want pyipopt to work for you, sorry.
the easiest way to handle this is to adjust the setup.py accordingly:
# When I installed Ipopt from source, I used the
# --prefix=/usr/local
# option, so this is where I want pyipopt to look for my ipopt installation.
# I only installed from source because the ipopt packaging
# for my linux distribution was buggy,
# so by the time you read this the bugs have probably been fixed
# and you will want to specify a different directory here.
IPOPT_DIR = '/usr/local/'
adjust IPOPT_DIR to the path where the library has been installed on your system, which of course should has been conducted anyway.
EDIT:
If you are installing from source, just use --prefix=/usr/local for the configure script and compile and install the library by running make; sudo make install. Then you don't have to change the setup.py file.
