無法打開擴展控制文件 citext.control

Question

環境

Ubuntu 20.04 和 Debian 10 分別帶有 Python 3.8 或 3.7。

已嘗試過 Postgresql 版本 11、12 和 14。

Psycopg2-二進制 2.8.6

概述

我正在嘗試安裝 Django 項目，但出現此錯誤：

psycopg2.errors.UndefinedFile: could not open extension control file "/usr/share/pgsql/extension/citext.control": No such file or directory

psycopg 開發人員告訴我這可能是 postgresql-contrib 庫的問題。 同樣，其他人已經能夠通過安裝postgresql-contrib來修復這個錯誤，但是，這對我不起作用。 我也試過安裝postgresql-12 。

我可以看到 citext.control 在/usr/share/postgresql/12/extension/citext.control可用，所以我嘗試了ln -s /usr/share/postgresql/12 /usr/share/pgsql沒有效果。

我還運行了CREATE EXTENSION citext; 在 Postgres 中，也沒有效果。

對此的任何支持將不勝感激，因為我希望這個項目已經上線！

非常感謝。

Answer 1

您是否嘗試python3-psycopg2包裝系統安裝python3-psycopg2 ？

我的 Ubuntu 20 設置已經安裝了這個，並且 postgresql 連接可以與 django 一起使用。

ii python3-psycopg2 2.8.4-2 amd64 Python 3 module for PostgreSQL

Answer 2

我在本地 django 服務器而不是遠程數據庫服務器上安裝了postgresql-contrib 。 在與 Postgresql 相同的服務器上安裝解決了該問題。
