Hi @dsehgal04, this was fixed last month: https://github.com/senaite/senaite.core/blob/master/setup.py#L96

Are you installing Senaite using the source code or the python egg?

Hi @Espurna I just followed the instructions from this page :

Hi @dsehgal04,

Okay, then you are using the python egg, and it means that you are holding from the last stable release. Probably this change was not yet included.

Now, you have three options:

The easiest one is to use SENAITE Docker (https://github.com/senaite/senaite.docker/ ).
Wait for next release…
You can use the source code from GitHub by configuring the buildout for development:

To use the code in your project, you’ll need to reference it in your buildout.cfg file by editing it:

Change or add the following section:

extensions =
    mr.developer

… And the following

auto-checkout = *
always-checkout = true

… Add src/senaite.addons to the develop section.:

develop =
    src/senaite.api
    src/senaite.core
    src/senaite.core.listing
    src/senaite.core.spotlight
    src/senaite.core.supermodel
    src/senaite.impress
    src/senaite.jsonapi
    src/senaite.lims
   (add here other SENAITE addons you want to include)

… Add sources:

[sources]
senaite.api = git git@github.com:senaite/senaite.api.git
senaite.core = git git@github.com:senaite/senaite.core.git
senaite.core.listing = git git@github.com:senaite/senaite.core.listing.git
senaite.core.spotlight = git git@github.com:senaite/senaite.core.spotlight.git
senaite.core.supermodel = git git@github.com:senaite/senaite.core.supermodel.git
senaite.impress = git git@github.com:senaite/senaite.impress.git
senaite.jsonapi = git git@github.com:senaite/senaite.jsonapi.git
senaite.lims = git git@github.com:senaite/senaite.lims.git

Clone the GitHub repos in your src/ directory from your Pone installation (usually under zinstance/src):

$ git clone https://github.com/senaite/senaite.core
$ git clone https://github.com/senaite/senaite.api
...

You need to rerun buildout for the changes to take effect.:

# from your buildout directory
./bin/buildout
