1.从官网git下载最新的poco源代码

在/usr/local路径下创建Poco文件夹，克隆Poco源代码

sudo git clone -b poco-1.13.3-release https://github.com/pocoproject/poco.git

2.等了一会后，报错啦！！！ 

error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly: CANCEL (err 8)

error: 3966 bytes of body are still expected

fetch-pack: unexpected disconnect while reading sideband packet

fatal: early EOF

解决办法如下：

git config --global http.postBuffer 600000

再重新克隆一下，就解决啦～ 

3.编译

cd poco/
sudo mkdir cmake-build
sudo cmake ..
cmake --build . --target install

4.安装

sudo cmake --build . --target install

安装效果如下，等待就好
