It's possible I should just open this is an issue on the Enchant package, but it could definitely be something I'm missing too. I'm using El Capitan and python 2.7. I tried a few things:
pip install penchant seems to successfully install pyenchant-1.6.6, but when I try to import enchant I get the error ImportError: The 'enchant' C library was not found. Please install it via your OS package manager, or use a pre-built binary wheel from PyPI. I followed the advice here and upgraded pip.
I followed the advice here and started with brew install enchant, but that gave the error
curl: (22) The requested URL returned error: 404 Not Found
Error: Failed to download resource "glib--patch"
Download failed: https://gist.githubusercontent.com/jacknagel/af332f42fae80c570a77/raw/7b5fd0d2e6554e9b770729fddacaa2d648327644/glib-hardcoded-paths.diff
I also downloaded the wheel here (second-to-last link) and tried to pip install it, but got the error that it is not a supported wheel on this platform.
Thoughts? Thanks.

I'm using the "import ldap" in a python code. This is on a windows 10 machine.
I installed the python-ldap module
pip3 install python-ldap
Installed the dependencies based on the instructions at Python Can't install packages
Also resolved all the pip deployment issues based on Installing python-ldap in a virtualenv on Windows
I'm now getting the following error when executing the import ldap statement. am I missing something here? Any ideas to resolve it?
thon39\site-packages\ldap\__init__.py", line 34, in <module>
import _ldap
ImportError: DLL load failed while importing _ldap: The specified module could not be found.
Visit the unofficial Python binaries page:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap
Download the appropriate WHL package for your system.
For example, if you're using Python 3.8 on an x64 system, download python_ldap‑3.3.1‑cp38‑cp38‑win_amd64.whl
(hint: do NOT download the +sasl version unless you have the Cyrus SASL code running on your system...)
Start the VirtualEnv for your project, if you're using one (C:\Users\youruser\.virtualenv\YourVirtualEnv\Scripts\activate.bat) -- if you're not, skip this step.
Then run pip3 install C:\Path\To\python_ldap_x.x.x-cpXX-cpXX-winXX.whl and this should install the Python DLL (pyd) file for you.
When I installed eric6, I was prompted with the following problems:
Python Version: 3.6.5
Found PyQt5
Found pyuic5
Sorry, please install QScintilla2 and its PyQt5/PyQt4 wrapper.
Error: DLL load failed: Cannot find the specified program!
But I have installed QScintilla via "pip install QScintilla", so what should I do next?
My operating system is Windows.
I see this error on today too , I used pip to install this module but all stop or fail, so I just can download 'whl' from pypi.org and 'pip install *.whl'. and re-install sip and PyQt5<5.9.3> before. And fixed. you can try it.
sip-4.19.4-cp36-none-win_amd64
PyQt5-5.9.2-5.9.3-cp35.cp36.cp37-none-win_amd64
QScintilla-2.10.1-5.9.1-cp35.cp36.cp37-none-win_amd64
install sequence: sip -> PyQt5 - QScintilla
I am following the instructions here: http://www.pyimagesearch.com/2017/03/27/how-to-install-dlib/
line by line, except for the line where python3 is installed. I made a virtual environment and inside the virtualenv, did these four lines:
$ pip install numpy
$ pip install scipy
$ pip install scikit-image
$ pip install dlib
Unlike the instructions, the last line took a few seconds, not 15 minutes. After the installation, I opened ipython and tried import dlib, and receive this message:
----> 1 from .dlib import *
2 __version__ = "19.4.0"
ImportError: dlopen(/Users/myname/Documents/camera-project/code/story-board/cv/lib/python2.7/site-packages/dlib/dlib.so, 2): Library not loaded: #rpath/libmkl_rt.dylib
Referenced from: /Users/myname/Documents/camera-project/code/story-board/cv/lib/python2.7/site-packages/dlib/dlib.so
Reason: image not found
I assume this means dlib is not properly installed, but I am not sure what I did wrong?
Also, I should add that I do not haveanaconda on my mac, so it cannot be the issue. However earlier today I did, and I could load dlib without an issue, presumably because I am running a version of python distributed by anaconda, and I assume dlib comes with anaconda. However the X11 distributed by anaconda is broken so I had to remove anaconda completely from my system and start over.
EDIT
This is the message I get after installing dlib "successfully":

Installing collected packages: dlib
Successfully installed dlib-19.4.0
You may need to install the pakage cmake.
When I tried installing dlib on my Mac in a virtualenv just now, I got the error
running bdist_wheel
running build
error: Cannot find cmake, ensure it is installed and in the path.
You can install cmake on OSX using `sudo brew install cmake`.
You can also specify its path with --cmake parameter.
So I would recommend trying to install cmake with
brew install cmake
I am using Win7 64 bit machine with Python 2.7 installed. I have installed swigwin 3.0.5. When I do "pip install M2Crypto" I got the following errors:
SWIG\_m2crypto.i(30) : Error: Unable to find 'openssl\opensslv.h'
SWIG\_m2crypto.i(33) : Error: Unable to find 'openssl\safestack.h'
SWIG\_evp.i(12) : Error: Unable to find 'openssl\opensslconf.h'
SWIG\_ec.i(7) : Error: Unable to find 'openssl\opensslconf.h'
In some links I found the suggestion is to install openssl-dev. But I could not find the equivalent package for windows (pip install openssl-dev does not work and I have done pip install pyOpenSSL which did not help me).
Thanks in advance for your help in this issue.
Not sure what your OS is. But to solve the issue on MAC OS X Yosemite you need to reinitialise xcode command line tools by using this command in terminal.
xcode-select --install
This solved the problem for me.
I'm struggling with installing MySQL-python on my Centos VPS. I have "main" Python 2.6 (one that came automatically with CentOS) and another one I installed after (2.7). So I used this command:
easy_install-2.7 MySQL-python
But it reproduces following error:
Searching for MySQL-python
Reading https://pypi.python.org/simple/MySQL-python/
Download error on https://pypi.python.org/simple/MySQL-python/: unknown url type: https -- Some packages may not be found!
Couldn't find index page for 'MySQL-python' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading https://pypi.python.org/simple/
Download error on https://pypi.python.org/simple/: unknown url type: https -- Some packages may not be found!
No local packages or download links found for MySQL-python
error: Could not find suitable distribution for Requirement.parse('MySQL-python')
Thanks for reading my question and possibly trying to help!
Perhaps you're using an old version of easy_install, that may be the root of problem. You can follow instructions from distribute doc package, and than install pip. Since you have installed pip you can install MySQL-pythoneasily.
Maybe try use some sentence,which include mysqldb.
