I used this command in terminal
sudo apt-get install python-setuptools
it throws up an error instead of installing -
Package 'python-setuptools' has no installation candidate
THis is a python package so you could use pip to install it
pip3 install setuptools
Try this:
sudo apt-get install python-pip
When pip is installed type in:
pip install setuptools
Hope this helps!
I'm trying to install Pillow (Python module) using pip, but it throws this error:
ValueError: jpeg is required unless explicitly disabled using --disable-jpeg, aborting
So as the error says, I tried:
pip install pillow --global-option="--disable-jpeg"
But it fails with:
error: option --disable-jpeg not recognized
Any hints how to deal with it?
There is a bug reported for Pillow here, which indicates that libjpeg and zlib are now required as of Pillow 3.0.0.
The installation instructions for Pillow on Linux give advice of how to install these packages. Note that not all of the following packages may be missing on your machine (comments suggest that only libjpeg8-dev is actually missing).
pip / PyPi (Pillow>3.4.2)
The latest releases of Pillow are available on PyPi as wheels — the new standard packaging mechanism for Python. These prebuilt packages include all neccessary binary dependencies to allow Pillow to run and should be used if you want to install Pillow using PyPi
To use wheels, you need to have a version of pip>=1.4. If you are using an earlier version (pip --version) upgrade pip using the following:
pip install --upgrade pip
Once pip is upgraded, pip install will use platform-specific wheel files by default if they are available. Use the following command to upgrade Pillow to the latest version available on PyPi:
pip install --upgrade pillow
Ubuntu 12.04 LTS or Raspian Wheezy 7.0
sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk
Ubuntu 14.04
sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
Ubuntu 18.04
sudo apt install libjpeg8-dev zlib1g-dev
Fedora 20
The Fedora 20 equivalent of libjpeg8-dev is libjpeg-devel.
sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel
Mac OS X (via Homebrew)
On Mac OS X with Homebrew this can be fixed using:
brew install libjpeg zlib
You may also need to force-link zlib using the following:
brew link zlib --force
Update April 2019: In Mojave the above will not work and you need to run the following as taken from this bug report on Pillow
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Update July 2016: There is no longer a formula for zlib available in the main repository (Homebrew will prompt you to install lzlib which is a different library and will not solve this problem).
There is a formula available in the dupes repository. You can either tap this repository, and install as normal:
brew tap homebrew/dupes
brew install zlib
Or you can install zlib via xcode instead, as follows:
xcode-select --install
Thanks to phoenix, Panos Angelopoulou, nelsonvarela, benjaminz and Kal in the comments
After these are installed the pip installation of Pillow should work normally.
On Raspberry pi II, I had the same problem. After trying the following, I solved the problem. The solution is:
sudo apt-get update
sudo apt-get install libjpeg-dev
Thank you #mfitzp. In my case (CentOS) these libs are not available in the yum repo, but actually the solution was even easier. What I did:
sudo yum install python-devel
sudo yum install zlib-devel
sudo yum install libjpeg-turbo-devel
And now pillow's installation finishes successfully.
The quickest fix is upgrate the pip. Did worked for me:
pip install --upgrade pip
This worked for me to solve jpeg and zlib error :
C:\Windows\system32>pip3 install pillow --global-option="build_e
xt" --global-option="--disable-zlib" --global-option="--disable-jpeg"
This worked for me.
`sudo apt-get install libjpeg-dev`
brew install zlib
on OS X doesn't work anymore and instead prompts to install lzlib. Installing that doesn't help.
Instead you install XCode Command line tools and that should install zlib
xcode-select --install
I had the ValueError: zlib is required unless explicitly disabled using --disable-zlib but upgrading pip from 7.x to 8.y resolved the problem.
So I would try to update tools before anything else.
That can be done using:
pip install --upgrade pip
The alternative, if you don't want to install libjpeg:
CFLAGS="--disable-jpeg" pip install pillow
From https://pillow.readthedocs.io/en/3.0.0/installation.html#external-libraries
Working successfuly :
sudo apt install libjpeg8-dev zlib1g-dev
Anyone with Python 3.9 you can only install Pillow 8.0, Any version lower than that wouldn't work. For more check here.
So you can run it like this:
pip install Pillow==8.0.0
BTW this is tested on pip 21.0.1 (python 3.9) on MacOS Big Sur 11.2
Try
pip install pillow
If it doesn't work, try clearing the
cache by pip install --upgrade pip
Then again run
pip install pillow
On debian / ubuntu you only need:
libjpeg62-turbo-dev
So a simple sudo apt install libjpeg62-turbo-dev
and a pip install pillow
I am constantly getting the
Cannot fetch index base URL https://pypi.python.org/simple/
whenever I try to pip install anything with the most recent pip version.
I read on some other questions that pip was having SSL related issues in its latest version and recommended to install pip 1.2.1.
How do I install a specific version of pip via easy_install for example?
You should be able to install pip with pip:
pip install --upgrade pip==1.2.1
Based on your context, you can uninstall as above and then run:
sudo easy_install pip==1.2.1
No more pesky SSL errors.
Uninstall any previous installation of pip. Considering you are using system wide installation,
sudo apt-get remove python-pip
and also,
pip uninstall pip
Now,
sudo apt-get install python-setuptools
sudo easy_install pip==<specific version>
sudo pip install virtualenv
It's preferred to use virtual environment though.
I am using Ubuntu 10.04, which supports Python up to version 2.6.5.
However, I need to install the package python-iso8601_0.1.4-2_all.deb,
which depends on python (>= 2.6.6-7~).
I can not upgrade the distro, since I am using some other packages
which are not supported in 10.10+
Thank you!
/Nico.
Thats likely to break far too many things. You are better of installing the ISO 8601 package as an egg from http://pypi.python.org/pypi/iso8601/ for example.
Install pip:
sudo apt-get install python-pip python-dev build-essential
sudo pip install --upgrade pip
sudo pip install --upgrade virtualenv
and then install your package:
sudo pip install iso8601
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
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap.
python 3.6 suit with
python_ldap-3.2.0-cp36-cp36m-win_amd64.whl
Deploy the file in :
c:\python36\Scripts\
install it with
python -m pip install python_ldap-3.2.0-cp36-cp36m-win_amd64.whl
sudo apt-get install build-essential python3-dev python2.7-dev libldap2-dev libsasl2-dev slapd ldap-utils python-tox lcov valgrind
Debian Reference :

For others: https://www.python-ldap.org/en/latest/installing.html
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
