No such file error libpq-fe.h when installing PostgreSQL package for R on Linux

Question

On R, I was trying to install the PostgreSQL package called the RPostgreSQL.

I tried to install it by issuing the statement in the command-line like so:

R

命令行语句显示输出：

R version 3.5.2 (2018-12-20) -- "Eggshell Igloo"

Type 'contributors()' for more information and

Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

然后我尝试安装软件包

install.packages("RPostgreSQL")

然后安装失败并显示此错误消息

In file included from RS-PQescape.c:7:0:
RS-PostgreSQL.h:23:14: fatal error: libpq-fe.h: No such file or directory
 #    include "libpq-fe.h"
              ^~~~~~~~~~~~
compilation terminated.

似乎 R 找不到名为libpq-fe.h. 解决这个问题的方法是什么？

Answer 1

事实证明，这可以通过安装 C 语言开发的库和头文件来解决。
