How to install python27-devel on Centos 6.5 - python

I have installed python 2.7.6 from source, but can't find how to install python-devel for python 2.7
yum install python27-devel
doesn't work. How to install it?

Thanks for your feedback. First of all, if you try to run yum install python27-devel, then you should get the message like this:
No package python27-devel available
Then I followed this link,
yum search python | grep -i devel
This will show you that you have python-devel.x86_64 package available if your OS is a 64 bit OS. If I am correct, then the following command should work fine as shown in the accepted answer:
yum install python-devel.x86_64

I run Centos 6.5 on Virtualbox and this command solved it.
# yum update
# yum install centos-release-SCL
# yum install python27

How do I install tkinter on RedHat?

I am trying to install tkinter on Redhat 7.7. I have tried every combination if "sudo yum install [whatever]" and every single time it comes up with "No package [whatever] available".
pip install tkinter
pip3 install tkinter
sudo yum install python3-tkinter
sudo yum install tkinter
sudo yum install python36-tkinter
sudo yum -y install python36u-tkinter
sudo yum -y install python36-tkinter
sudo yum install tkinter
sudo yum install python36-tkinter
sudo yum install python35-tkinter.x86_64
...etc
I have tried to find what repository I might need to enable but RedHat support is all behind a pay wall. What repository do I need to enable?
At this point I am actually considering just switching to Ubuntu as RedHat is giving me all sorts of problems.
EDIT: I tried yum search tkinter and got the following:
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
manager
Repo rhel-7-workstation-rpms forced skip_if_unavailable=True due to:

python3.x86_64 : Interpreter of the Python programming language
I already have python3 installed. I don't know if had I installed via sudo yum install python3.x86_64 vs sudo yum install python3 I would have got different results.
This works for me!
sudo yum search tkinter
sudo yum install python3-tkinter.x86_64
Alright, so I managed to fix this to my satisfaction. What I did is outlined here. First I installed ActiveState's ActiveTcl 8.5, then rebuilt python 3.6 manually by downloading the source using the following:
$: ./configure --with-tcltk-includes='-I/opt/ActiveTcl-8.5/include'
--with-tcltk-libs='/opt/ActiveTcl-8.5/lib/libtcl8.5.so /opt/ActiveTcl-
8.6/lib/libtk8.5.so'
$: make
$: make install
Because I had a couple different versions of Python 3.x, I had to add the following to the .bashrc:
export PYTHONPATH=/usr/local/lib/python36.zip:/usr/local/lib/python3.6:/usr/local/lib/python3.6/lib-dynload:/usr/local/lib/python3.6/site-packages:/usr/local/lib64/python3.6/site-packages
One big issue I ran into was first manually installing Python 3.8 (which came out yesterday) for which there seems to be little support for most packages so far, so be advised. I also had a few system-specific issues with pip.

Install python3-venv module on linux mint

I was able to move to Linux mint 17.3 64 bit version from my Linux mint 16. This was long awaited migration.
After moving to Linux Mint 17.3, I am not able to the install python3-venv module, which is said to be the replacement for virtualenv in python 3.x. In my linux mint 16 I had access to pyvenv-3.4 tool. I dont know when I installed that module in Linux mint 16.
Anybody faced this issue ?
python -m venv test
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.
izero#Ganesha ~/devel $ sudo apt-get install python3-venv
[sudo] password for izero:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package python3-venv
Try running this command:
sudo apt-get install python3.4-venv
Then use this:
python3 -m venv test
the package name is python3.4-venv and not python3-venv.
For python 3.6 I found out it was a locale issue, running this:
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales
Seems to solve the issue.
Source from this answer
I use python 3.6 , and so the following did the trick for me:
$ sudo apt-get install python3.6-venv
(the problem was that apt-get install python3-venv would virtualenv for 3.5)
Update all packages
sudo apt-get update
Install virtual environment 3
apt-get install python3-venv
apt install virtualenv
Check that it has been installed
virtualenv --version
Note: that this is for ubuntu 20 or variants

Can't find Python.h file on CentOS

I am trying to compile a Python extension written in C on a CentOS machine. I am getting
error: Python.h: No such file or directory
It works fine on ubuntu, where I have python-dev installed using apt-get.
I tried installing python-devel using
yum install python-devel
but it is already installed. How do I fix this error?
If you using python3 You could install python34-devel for that
It's available on EPEL Repository and has python34-devel package available
You simply just run this command to get it installed
yum install python34-devel
Hope it's help
*note At this time python34-devel is the most updated version of python 3.4
On my system the Python.h header file is in the path /usr/include/python2.6/. As this path is not searched by the pre-processor by default, you have to add it to the list of paths to search. This is done with the -I option to the compiler, like this:
$ gcc -I/usr/include/python2.6 source.c -o program
Change the path above to the actual path on your system. You can find it either with the find command as proposed in a comment, of with the locate command if it's installed.
for CentOS 7.4
Python 3.6.6 : yum -y install python36-devel
Python 2 : yum -y install python-devel
for Ubuntu
Python 3.6: apt-get install libpython3.6-dev
For centos 8+
dnf install -y python3-devel
If your are running Centos 8 , you can use :
dnf install -y python38-devel
dnf install -y python3-devel did not work for me.
I had a similar problem where default Python was 2.7 but pip was running against 3.4, and I wanted to use 2.7. So I did: yum remove python34-pip and yum install python2-pip. Solved it!
I too had similar problem.
./python/py_defines.h:39:20: fatal error: Python.h: No such file or
directory
Whereas the find command showed that the python.h exists.
The above solutions did not work however the below command execution worked for me.
yum install python27-python-devel.x86_64
Not much different but wasted lots of time.
Install python3.4 (include pip) & python3.4-dev packages on Centos6.X:
yum install http://dl.iuscommunity.org/pub/ius/stable/CentOS/6/x86_64/python34u-3.4.2-1.ius.centos6.x86_64.rpm
yum install http://dl.iuscommunity.org/pub/ius/stable/CentOS/6/x86_64/python34u-devel-3.4.2-1.ius.centos6.x86_64.rpm
This depends on the Python you have!
You need a dev package, the version X.X.X for Python X.X.X you have, you can search on https://centos.pkgs.org/7/ius-x86_64.
By example, if you have Python 3.6.5 from IUS, you need to install https://centos.pkgs.org/7/ius-x86_64/python36u-devel-3.6.5-1.ius.centos7.x86_64.rpm.html.
I had the same problem with Python3.9 on Centos8. I fixed it by installing as below:
dnf install -y python39-devel

I can't install python-ldap

When I run the following command:
sudo pip install python-ldap
I get this error:
In file included from Modules/LDAPObject.c:9:
Modules/errors.h:8: fatal error: lber.h: No such file or directory
Any ideas how to fix this?
The python-ldap is based on OpenLDAP, so you need to have the development files (headers) in order to compile the Python module. If you're on Ubuntu, the package is called libldap2-dev.
Debian/Ubuntu:
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
RedHat/CentOS:
sudo yum install python-devel openldap-devel
To install python-ldap successfully with pip, following development libraries are needed (package names taken from ubuntu environment):
sudo apt-get install -y python-dev libldap2-dev libsasl2-dev libssl-dev
On CentOS/RHEL 6, you need to install:
sudo yum install python-devel
sudo yum install openldap-devel
and yum will also install cyrus-sasl-devel as a dependency. Then you can run:
pip-2.7 install python-ldap
"Don't blindly remove/install software"
In a Ubuntu or Debian based distro, you can use apt-file to find the name of the exact package that includes the missing header file.
# do this once
sudo apt-get install apt-file
sudo apt-file update
$ apt-file search lber.h
libldap2-dev: /usr/include/lber.h
As you could see from the output of apt-file search lber.h, you'd just need to install the package libldap2-dev.
sudo apt-get install libldap2-dev
In Ubuntu it looks like this :
$ sudo apt-get install python-dev libldap2-dev libsasl2-dev libssl-dev
$ sudo pip install python-ldap
Windows: I completely agree with the accepted answer, but digging through the comments took a while to get to the meat of what I needed. I ran across this specific problem with Reviewboard on Windows using the Bitnami. To give an answer for windows then, I used this link mentioned in the comments:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap
placed that wheel (whl file) into my reviewboard install directory
Then, executed the following commands
easy_install pip
pip install python_ldap-2.4.20-cp27-none_win32.whl
(because I had python 2.7 and a 32bit install at that)
easy_install python-ldap
For those having the same issue of missing Iber.h on Alpine Linux, in a docker image that you are trying to adapt to Alpine for instance.
The package you are looking for is: openldap-dev
So run
apk add openldap-dev
Available from version 3.3 up to Edge
Available for both armhf and x86_64 Architectures.
On Fedora 22, you need to do this instead:
sudo dnf install python-devel
sudo dnf install openldap-devel
On openSUSE you need to install the packages openldap2-devel, cyrus-sasl-devel, python-devel and libopenssl-devel.
zypper install openldap2-devel cyrus-sasl-devel python-devel libopenssl-devel
python3 does not support python-ldap. Rather to install ldap3.
For alpine docker
apk add openldap-dev
if the python version is 3 and above try
pip install python3-ldap
I had problems with the installation on Windows, so one of the solutions is to install the ldap package manually.
A few steps:
Go to the page pyldap or/and python-ldap and download the latest version *whl.
Open a console then cd to where you've downloaded your file like some-package.whl and use:
pip install some-package.whl
The current version for pyldap is 2.4.45. On a concrete example the installation would be:
pip install .\pyldap-2.4.45-cp37-cp37m-win_amd64.whl
# or
pip install .\python_ldap‑3.3.1‑cp39‑cp39‑win_amd64.whl
Output:
Installing collected packages: pyldap
Successfully installed pyldap-2.4.45
EDIT
You can install the proper version for Python-3.X though using following command:
# if pip3 is the default pip alias for python-3
pip3 install python3-ldap
# otherwise
pip install python3-ldap
Also here is the link of PiPy package for further information: python3-ldap 0.9.8.4
OR
ldap3 is a strictly RFC 4510 conforming LDAP V3 pure Python client library. The same codebase runs in Python 2, Python 3, PyPy and PyPy3: https://github.com/cannatag/ldap3
pip install ldap3
from ldap3 import Server, Connection, SAFE_SYNC
server = Server('my_server')
conn = Connection(server, 'my_user', 'my_password', client_strategy=SAFE_SYNC, auto_bind=True)
status, result, response, _ = conn.search('o=test', '(objectclass=*)')
# usually you don't need the original request (4th element of the returned tuple)
For most systems, the build requirements are now mentioned in python-ldap's documentation, in the "Installing" section.
If anything is missing for your system (or your system is missing entirely), please let maintainer know!
(As of 2018, I am the maintainer, so a comment here should be enough. Or you can send a pull request or mail.)
To correct the error due to dependencies to install the python-ldap : Windows 7/10
download the whl file

python 3.6 suit with
python_ldap-3.2.0-cp36-cp36m-win_amd64.whl
Deploy the file in :

On OSX, you need the xcode CLI tools. Just open a terminal and run:
xcode-select --install
For ArchLinux/Manjaro for me helped the following command:
yay libldap24
As of december 2021 there was/is a strange problem with the ldap library (at least in arch/manjaro).
While installing python-ldap (at 'Building wheel for python-ldap') I got the message 'ERROR: Failed building wheel for python-ldap':
/usr/bin/ld: cannot find -lldap_r
collect2: error: ld returned 1 exit status
error: command '/usr/bin/gcc' failed with exit code 1
a workaround is provided here: https://github.com/python-ldap/python-ldap/issues/432#issuecomment-974799221
I cite:
As a workaround create the file /usr/lib64/libldap_r.so with content
INPUT ( libldap.so ). The approach works on all systems that use a GNU
ld-compatible linker.
# cat > /usr/lib64/libldap_r.so << EOF
INPUT ( libldap.so )
EOF
In FreeBSD 11:
pkg install openldap-client # for lber.h
pkg install cyrus-sasl # if you need sasl.h
pip install python-ldap
As a general solution to install Python packages with binary dependencies [1] on Debian/Ubuntu:
sudo apt-get build-dep python-ldap
# installs system dependencies (but not the package itself)
pew workon my_virtualenv # enter your virtualenv
pip install python-ldap
You'll have to check the name of your Python package on Ubuntu versus PyPI. In this case they're the same.
Obviously doesn't work if the Python package is not in the Ubuntu repos.
[1] I learnt this trick when trying to pip install matplotlib on Ubuntu.
If you're working with windows machines, you can find 'python-ldap' wheel in this Link and then you can install it
for those who are using alphine linux,
apk add openldap-dev
try:
ARCHFLAGS="-arch x86_64" pip3 install python-ldap
Adding also libzbar-dev solved for me the installation of python-ldap when building DOCKER
The full command becomes:
apt-get install -y python-dev libldap2-dev libsasl2-dev libssl-dev libzbar-dev
A hack answer for FreeBSD 13.1 (yes, I know this is deep South of best practices, but I just needed a quick fix):
pkg install openldap24-client
cd /usr/local/include/python3.9
ln -s ../<all of the below> .
lber.h
lber_types.h
ldap.h
ldap_cdefs.h
ldap_features.h
ldap_schema.h
ldap_utf8.h
openldap.h
sasl
pip install python-ldap

PIP not available from command line

I am using CentOS. It has Python 3.6 version installed.
From command line if I try to execute PIP, I get error: "Command not found"
How to add Python folder to the environment path?
Pip is not available in CentOS 7 core repositories. To install pip we need to enable the EPEL repository:
sudo yum install epel-release
Once the EPEL repository is enabled we can install pip and all of its dependencies with the following command:
sudo yum install python-pip
To verify that the pip is installed correctly run the following command which will print the pip version:
pip --version
Enjoy! :)
Apparently you should install pip separately in CentOS.
Try this Link.
