Question

我正在尝试在Ubuntu 20.04上安装Odoo 13，我按照不同的步骤进行安装，例如this one，但我总是遇到此 psycopg2 错误（在本段下面）），当我到达安装requirements.txt组件的步骤时，此错误仅在python虚拟环境中发生。

错误：

  It appears you are missing some prerequisite to build the package from source.

  You may install a binary package by installing 'psycopg2-binary' from PyPI.
  If you want to install psycopg2 from source, please install the packages
  required for the build and try again.

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

  ERROR: Failed building wheel for psycopg2

我尝试手动安装不同版本的psycopg2，但没有成功。如果我不使用虚拟环境，则不会出现错误，安装过程将完全成功。

Answer 1

pip install psycopg2-binary（适用于ubuntu）和pip install psycopg2（适用于Windows）

Answer 2

与Python 3.8一起安装Odoo13对于许多软件包（包括psycopg2，Pillow，Python-ldap等）来说有点问题，有时候我花了很多时间但我却能够在python 3.8上运行20.04 我稍微修改了requirment.txt文件，然后观看我的github链接-

https://github.com/tanvirahmedkhan74/Installing-Odoo13-on-Ubuntu20.04-with-Python-3.8.git

在github上用给定的一个替换requirments.txt文件

Answer 3

ubuntu20中的

odoo，具有连接自定义asddons存储库的选项 https://github.com/jerichoruz/odoo-instal-sh

Answer 4

首先安装枕头 pip3 install pillow 比通过安装安装psycopg2 sudo apt install python3-dev libpq-dev 通过运行来验证是否安装了pg_config pg_config --version 如果没有添加到路径 export PATH=/usr/lib/postgresql/X.Y/bin/:$PATH 之后 pip install psycopg2 接下来，从requirements.txt中删除psycopg2和枕式包装机然后重新运行 pip3 install -r requirements.txt
