i used this
git clone https://github.com/indico/indico.git src

I still need a dev environment as there are a some translation fixes and custom menu etc.,

thanks

You need to git checkout 2.3-maintenance inside the src folder…

Recreate your virtualenv, you probably have some wrong versions from attempting to install some 3.0 deps

i did recreate but

should I change the OS. I am trying to use Centos 7. Should I try with Ubuntu?

28

Doesn’t really matter. Ubuntu and CentOS7 should both work fine.

Since it fails at the psycopg2 wheel my guess would be that there’s something some yum dependency such as libpq-devel missing. But since you omitted the “complete output” part I cannot for sure :wink:

hi, I managed to install Indico Dev in Centos 7 using following set of commands

yum install epel-release
yum update
sudo yum -y install https://packages.endpoint.com/rhel/7/os/x86_64/endpoint-repo-1.7-1.x86_64.rpm
sudo yum install git
sudo vi /etc/yum.repos.d/CentOS-Base.repo
Find the [base] and [updates] sections, enter insert mode by pressing i, and insert the exclude=postgresql* line in both sections. As a result, your file will look like the following, with
sudo yum install https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
yum list postgresql*
sudo yum install postgresql96-server
sudo yum install postgresql96-contrib postgresql96-devel
systemctl start redis.service postgresql-9.6.service
sudo /usr/pgsql-9.6/bin/postgresql96-setup initdb
yum install -y gcc redis python-devel python-virtualenv libjpeg-turbo-devel libxslt-devel libxml2-devel libffi-devel pcre-devel libyaml-devel redhat-rpm-config libpq-devel
yum install httpd
useradd -rm -g apache -d /opt/indico -s /bin/bash indico

pip install pyrsistent==0.16.1
pip install -e .
npm ci
indico setup wizard --dev
indico db prepare
indico i18n compile-catalog
indico i18n compile-catalog-react

but when I run it with

(env) [indico@localhost src]$ indico run -h 10.10.10.106 -q --enable-evalex
 * Serving Indico on http://10.10.10.106:8000

 * Werkzeug debugger console is available to all clients!
 * Running on http://10.10.10.106:8000/ (Press CTRL+C to quit)

accessing http://10.10.10.106:8000 timed out. Looking at indico log at (/opt/indico/dev/indico/data/log/indico.log) shows me only following

2021-04-27 04:34:32,443 ERROR 0000000000000000 - indico.i18n Configured DEFAULT_LOCALE (en_GB) does not exist

31

The message about the locale is weird, en_GB should exist as long as you executed indico i18n compile-catalog before starting indico. Anyway, the warning is harmless and safe to ignore.

If you get a timeout it sounds like the issue is not related to indico but maybe your local firewall?

32

i did add port 8000 on firewall

[root@localhost ~]# firewall-cmd --permanent --add-port=8000/tcp
success
[root@localhost ~]# firewall-cmd --reload
success

following errors are flooding on watch terminal

33

This may help… anyway it’s just an error from the file modification watcher used by the assets builder, so probably harmless. I’d still raise the max inotify watchers to avoid the error spam.

i just noticed this line in HTTPD error log. Could this be the reason?

[proxy:error] [pid 1099] (111)Connection refused: AH00957: uwsgi: attempt to connect to 127.0.0.1:8008 (127.0.0.1) failed

36

I don’t understand how uwsgi is involved there - in a development setup it’s not being used at all…

37

i remove it but still does not help.

here is my VM running on VMware player 14.0 root password is: Test
can you please have a look what could be wrong. Thanks in advance.

38

Sorry, I don’t really have time for that (and I’d have to install vmware first).

My recommendation would be to use a clean VM and then just follow the dev setup guide - with the only difference that you need to git checkout 2.3-maintenance after cloning the repo.

39

I am so noob, followed the documentation at Installation guide (development) — Indico 2.3.4 documentation and 4th time failing.

40

my 5th attempt was success. Now I have got the dev running. Following is the exact set of commands I used to get it running.
PS: There was only 1 error as follows

ERROR: pip’s legacy dependency resolver does not consider dependency conflicts when selecting packages. This behaviour is the source of the following dependency conflicts.
sphinx-rtd-theme 0.5.2 requires docutils<0.17, but you’ll have docutils 0.17.1 which is incompatible.

but still it got the dev console running
