Question

我使用基于CentOS 7（x64）Linux的计算机上的Enterprise DB here的单击安装程序，在PostGIS 2.3中安装了PostgreSQL 9.6。现在我正在尝试将R Studio连接到Postgres。为此，我尝试在R Studio中安装RPostgreSQL包，但我收到以下错误：

PostgreSQL 9.6的安装目录是/opt/PostgreSQL/9.6/bin，它似乎不在上面的错误中。有人可以帮我解决这个错误吗？

编辑1：

感谢@lavajumper的建议，我摆脱了上述错误。但现在得到这个错误，显示一些丢失的HTML链接。

好的，我自己想出了问题。 @Manoj在this链接给出的答案帮助我解决了第二个错误。根据上面提到的链接，RPostgreSQL仅检查这些目录中的库：

/usr/lib 
/usr/lib/pgsql 
/usr/lib/postgresql 
/usr/local/lib 
/usr/local/lib/pgsql 
/usr/local/lib/postgresql 
/usr/local/pgsql/lib 
/usr/local/postgresql/lib 
/opt/lib 
/opt/lib/pgsql 
/opt/lib/postgresql 
/opt/local/lib 
/opt/local/lib/postgresql 
/opt/local/lib/postgresql84 
/sw/opt/postgresql-8.4/lib 
/Library/PostgresPlus/8.4SS/lib 
/sw/lib

因此，作为超级用户，我将库文件从Postgres安装目录复制到/usr/lib并在R Studio中再次运行命令：

 install.packages('RPostgreSQL', dependencies=TRUE, repos='http://cran.rstudio.com/')

它有效！：）
