ERROR: Could not build wheels for python-ldap, which is required to install pyproject.toml-base proj

报错：

odoo安装 python-ldap 报错pyproject.toml-based，实际上，这个是一个Python3 安装报错。

下面是原始安装报错输出：

Collecting python-ldap

Building wheels for collected packages: python-ldap
  Building wheel for python-ldap (pyproject.toml) ... error

 这里是一堆报错输出。。。

  × Building wheel for python-ldap (pyproject.toml) did not run successfully.Collecting python-ldap
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for python-ldap

解决：

根本原因是由于操作系统没有完整安装必要的组件导致。
在安装应用前，请执行如下把操作系统更新至最新：

$ sudo apt update && sudo apt upgrade   //把操作系统更新至最新

执行组件更新：

$ sudo apt-get install libsasl2-dev python3-dev libldap2-dev libssl-dev

执行完成后，接着执行python-ldap安装：

$ pip install python-ldap

安装成功结果输出：
