pjsua2网上很多教程都安装失败，记录下正确的安装过程。

pip命令安装会提示如下错误：

(pjsip) [root@L-AP-10-88 ~]# pip3 install pjsua2
Collecting pjsua2
  Using cached pjsua2-2.12.tar.gz (329 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error
  
  × python setup.py egg_info did not run successfully.
  │ exit code: 1

              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
      FileNotFoundError: [Errno 2] No such file or directory: '../../../../version.mak'
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

采用编译的方式安装：

wget https://github.com/pjsip/pjproject/archive/refs/tags/2.15.1.tar.gz
tar -zxvf ./2.15.1.tar.gz
cd pjproject-2.15.1/
ls
./configure --enable-shared --with-python=python3
make dep
make
make install
ldconfig

# 下一步前需要安装swig，根据操作系统采用1或者2的方式
#1 ubuntu 直接安装
apt-get install swig python3-dev

#2 centos 采用包安装 
# 下载 SWIG 4.0.2
wget https://download.sourceforge.net/swig/swig-4.0.2.tar.gz
# 解压
tar xvf swig-4.0.2.tar.gz
cd swig-4.0.2
# 配置、编译并安装
./configure --prefix=/usr/local
make
sudo make install
# 检查是否安装成功
swig -version

# 这步非常重要，特别是路径
cd pjsip-apps/src/swig/python
make
python3 setup.py build
