ERROR: Could not build wheels for python-ldap, which is required to install pyproject.toml-based projects

Question

I was installing Odoo 15 inside a Python virtual environment on Ubuntu 20.04. I've downloaded Odoo from the official GitHub repository and use Nginx as a reverse proxy.

after following the documentation to install and set up odoo in ubuntu 22.04, I did followed this how-to-do doc in this link

I get this error the moment I do install pip packages using the command pip install -r requirement.txt any help please.

          Python recognizes 'slapdtest.certs' as an importable package,
          but it is not listed in the `packages` configuration of setuptools.
      
          'slapdtest.certs' has been automatically added to the distribution only
          because it may contain data files, but this behavior is likely to change
          in future versions of setuptools (and therefore is considered deprecated).
      
          Please make sure that 'slapdtest.certs' is included as a package by using
          the `packages` configuration field or the proper discovery methods
          (for example by using `find_namespace_packages(...)`/`find_namespace:`
          instead of `find_packages(...)`/`find:`).
      
          You can read more about "package discovery" and "data files" on setuptools
          documentation page.

Please, take a look at how do I format code blocks – Vernacularize

Answer 1

You need to install on your system the GCC compiler package and the package that includes the development libraries and header files needed to compile applications that use LDAP

Resorcinol

Can you please introduce them with more details? – Cheyennecheyne

Package names depends on your Linux distribution. You can use the search command in your package manager to find the packages you need. – Resorcinol

Does this work on windows operating system, am stucked with this error in subject. I have Installed Visual C++ Build tools but still am not able to install ldap – Drafty

You can find links to unofficial pre-compiled packages for Windows on the Installing python-ldap page of the python-ldap documentation. – Resorcinol

Answer 2

This issue is because in your system you don't have python-dev. Also use python 3.8+. However To solve your issue Use below code in terminal:

sudo apt-get install python3-dev libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev build-essential libssl-dev libffi-dev libmysqlclient-dev libjpeg-dev libpq-dev libjpeg8-dev liblcms2-dev libblas-dev libatlas-base-dev

Secor

Worth to mention you may need to install something like python3.11-dev, version specific library instead of just python3-dev. – Drainpipe

Answer 3

If you are using RPM based distributions with the YUM package manager, run this command in your terminal to resolve the issue:

sudo yum install openldap-devel

Answer 4

Downgrading libldap-2.5.0 to the right version (sudo apt install libldap-2.5-0=2.5.16+dfsg-0ubuntu0.22.04.2) was the solution for me to install libldap2-dev which in turn gave me the possibility to pip install the requirements file (was on Ubuntu 22.04 though)

Answer 5

A similar challenge arose for me when installing Odoo Server 17.0 Community Edition on Ubuntu 22.04.4 LTS (Jammy Jellyfish), utilizing Python 3.10.12. I found that using python3-ldap instead of python-ldap could potentially resolve this issue, particularly if you're working with Python 3 or a later version. To implement this solution, you can simply replace the line python-ldap==... in the requirements.txt file with python3-ldap.
