Getting error when trying to 'go get' the geos package
问题
我尝试运行一个新的Golang项目，我已经安装了所有的东西，但是我遇到了以下问题：
$ go get github.com/paulsmith/gogeos/geos
#### #github.com/paulsmith/gogeos/geos
In file included from ..\..\go\pkg\mod\github.com\paulsmith\gogeos@v0.1.2\geos\coordseq.go:4:
./geos.h:1:10: fatal error: geos_c.h: No such file or directory
1 | #include <geos_c.h>
| ^~~~~~~~~~
compilation terminated.

根据项目页面上的安装说明，看起来你需要先安装GEOS；请参考这部分：https://github.com/paulsmith/gogeos#requirements
在Ubuntu上，可以简单地使用$ apt-get install libgeos-dev进行安装，但上面的链接也提供了从源代码安装的说明。
在你的情况下，Go包很可能使用cgo从GEOS加载C代码，但由于未安装GEOS且cgo无法找到头文件，所以加载失败。
英文:
Looking at the installation instructions on the project's page, it seems like you have to install GEOS first; see this part: https://github.com/paulsmith/gogeos#requirements
It can be as easy as $ apt-get install libgeos-dev on Ubuntu, but the link above has instructions for a from-source installation as well.
What happens in your case is that the Go package likely uses cgo to load C code from GEOS, and it fails immediately because GEOS is not installed, and cgo cannot find the headers files.
