Problems with 'pyenchant', CentOS (& El Capitan)

Problem Statement

I am having problems running a python file that import's the enchant library. I've installed the enchant module with the following command:

$ pip install -U pyenchant
> Requirement already up-to-date: pyenchant in /usr/lib/python3.4/site-packages


My Python Environment

$ cat /etc/*-release
CentOS Linux release 7.2.1511 (Core)

$ cat ~/.zshrc
...
export PYTHONPATH=/usr/lib/python3.4/site-packages
alias py="python3"
alias pip="pip3"
...

$ py --version
Python 3.4.3

$ pip --version
pip 8.1.1 from /usr/lib/python3.4/site-packages (python 3.4)

$ echo $PYTHONPATH
/usr/lib/python3.4/site-packages

$ ls -al /usr/lib/python3.4/site-packages | grep enchant
drwxr-xr-x  5 root root 4096 13 apr 13:56 enchant
drwxr-xr-x  2 root root 4096 13 apr 13:56 pyenchant-1.6.6.dist-info

$ yum list installed | grep python-enchant
((nothing))


My Python File

$ cat ~/diskchall.py
import enchant

dictionary = enchant.Dict("en_US")
...


Running the file

$ py ~/diskchall.py
Traceback (most recent call last):
  File "/root/diskchall.py", line 1, in <module>
    import enchant
  File "/usr/lib/python3.4/site-packages/enchant/__init__.py", line 92, in <module>
    from enchant import _enchant as _e
  File "/usr/lib/python3.4/site-packages/enchant/_enchant.py", line 143, in <module>
    raise ImportError(msg)
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.


OS X El Capitan - TypeError

Did pretty much the same steps on El Capitan, but when running it gave me a TypeError.

Fixed by changing the _enchant.py file as suggested by this issue.

Pretty much a shame that this commit was from 2014 and still hasn't made the Pip repo.

In case you have Python 2.7 and Centos 7 (any minor version) these are the steps to install and run enchant library. 1. Install epel release for centos7, following other dependencies for enchant. 

RUN rpm -Uvh ./rpms/epel-release-7-11.noarch.rpm
RUN rpm -Uvh ./rpms/hunspell-1.2.8-16.el6.x86_64.rpm
RUN rpm -Uvh ./rpms/hunspell-en-US-0.20121024-6.el7.noarch.rpm
RUN rpm -Uvh ./rpms/hunspell-1.3.2-15.el7.x86_64.rpm
RUN rpm -Uvh ./rpms/enchant-1.6.0-8.el7.x86_64.rpm
RUN rpm -Uvh ./rpms/aspell-0.60.6.1-9.el7.x86_64.rpm
RUN rpm -Uvh ./rpms/enchant-aspell-1.6.0-8.el7.x86_64.rpm
RUN rpm -Uvh ./rpms/python-enchant-1.6.5-14.el7.noarch.rpm

This will install pyenchant library with spell checker for EN (you can change it accordingly to any other language) and aspell interface for PY and hunspeller.

It looks like you are missing at least one dependency the 'enchant' C library. It is either called libenchant or enchant. The python module is a wrapper around this library so you need this library to use the wrapper. To see what is available try:

yum whatprovides '*enchant*'

Your command 

yum list installed | grep python-enchant

will not show python-enchant as you installed it with pip not yum. Instead try:

pip freeze | grep enchant

A list of dependencies for one a build of python-enchant can be seen here note the requirement for enchant >= 1.5.0 (sometimes called libenchant)

On RedHat a simple "yum whatprovides enchant" will do:

yum whatprovides enchant
...
Repo        : rhel6-base-x86_64
...
1:enchant-1.5.0-4.el6.i686 : An Enchanting Spell Checking Library
Repo        : rhel6-base-x86_64
...
1:enchant-1.5.0-5.el6.i686 : An Enchanting Spell Checking Library
Repo        : rhel6-base-x86_64
...
1:enchant-1.5.0-5.el6.x86_64 : An Enchanting Spell Checking Library
Repo        : rhel6-base-x86_64
...

Install it with:

yum install enchant
