Question

我已经使用conda激活了venv

$ source激活/ home / sim / anaconda3 / envs / myenv

我在(myenv) sim@ma-Vostro-15-3568:~/flask/venv$行事中

python3 -m pip install psycopg2

我也尝试过pip3

python --version是3.6

错误在下面

    Error: pg_config executable not found.

    pg_config is required to build psycopg2 from source.  Please add the directory
    containing pg_config to the $PATH or specify the full executable path with the
    option:

        python setup.py build_ext --pg-config /path/to/pg_config build ...

    or with the pg_config option in 'setup.cfg'.

    If you prefer to avoid building psycopg2 from source, please install the PyPI
    'psycopg2-binary' package instead.

    For further information please check the 'doc/src/install.rst' file (also at
    <http://initd.org/psycopg/docs/install.html>).
