What’s written here doesn’t help, at least the first answer.

Answer 1

You don’t have psycorg2 installed (pgadmin4 dependency is likely). When installing pgadmin4, pip automatically tries to install the required dependencies (only Python libraries — pip does not install third-party non-Python software as a rule).

The error in the question arises from an attempt to compile psycorg2 from source (pg_config command not found). On my system, / usr / bin / pg_config is in the postgresql-common Ubuntu package (it doesn’t matter since the actual system install is sudo apt-get install python -psycopg2 or a similar command does).

Install psycorg2 of the correct version on your system and repeat the pip command for pgadmin4.

We are interested in the version that the pip command sees:

$ pip show psycopg2

If you want to build a newer version from source, then to automatically install dependencies for compilation, you can run:

$ sudo apt-get build-dep python-psycopg2

And rerun pip install with the desired version restrictions.

Install the following package:

sudo apt-get install libpq-dev
