Have the same problem - use nextcloud docker compose for apache (Nextcloud Hub 6 (27.1.1)) Try to installing langchain via pip3 install langchain which fails and complain "This environment is externally managed..."

thanks best regards Jochen

marcelklehr commented 1 year ago

Which docker container are you using? You do need python-venv in the container, which may not be there in the default images. I've just successfully installed the app on the 27.1.1-apache container with

apt update && apt install python3.11-venv
php occ app:enable llm

on the alpine things inevitably fail, for lots of reasons. (one of them being that poetry wants to build some native python modules)

jjqoie commented 1 year ago

thx for your reply

my dockerfile is based on nextcloud:27-apache which has installed NEXTCLOUD_VERSION 27.1.1

FROM nextcloud:27-apache

RUN apt-get update && apt-get install -y procps smbclient && rm -rf /var/lib/apt/lists/ RUN echo '0 4 php -f /var/www/html/occ preview:pre-generate' >> /var/spool/cron/crontabs/www-data

COPY mpm_prefork.conf /etc/apache2/mods-enabled/

COPY my.cnf /etc/mysql/

I will add python3.11-venv to the image and redeploy - let's see...
