[Solved] LDAP Update issue on development environment

Install / Update Deployment

Hi

Just a heads up. I hit this issue twice on separate instances of frappe/erpnext dev virtualbox

During update process, update was halted with a compilation error for the python-ldap module:

Command "/home/frappe/frappe-bench/env/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-iP8He3/python-ldap/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-iEKLhr-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/frappe/frappe-bench/env/include/site/python2.7/python-ldap" failed with error code 1 in /tmp/pip-build-iP8He3/python-ldap/

Just documenting this here in case any one else has this issue.

If you are on ubuntu(as the virtualbox images are) the following will fix the issue:

sudo apt install -y libsasl2-dev python-dev libldap2-dev libssl-dev

This is due to missing headers for the ldap library

Hi,

had the same problem. Your remedy solved the problem.

Thank you.

To the ErpNEXT-Pros :slight_smile:

In general terms,

i have observed sometimes such problems with required elements to be installed for a proper upgrade using bench.

It seems to be a common problem.
So it would be a good idea to find a mechanism, which installs such requirements during the upgrade process. This may be needed to be defined by the developers, because some requirements can not been resolved automatically.

@Felipe_Orellana

You will need to install following packages depending upon your OS

For Ubuntu or Debian based system:
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev

For CentOS or RHEL based system:
sudo yum install python-devel, openldap-devel

After this run bench update. Hope this solves your problem :smiley:

@shreyasp Yup I’ve already solve it just documenting here in case people search the forum for the issue.
