如何在Linux Ubuntu 16上安装luasql？

Question

感谢StackOverflow社区的帮助,我能够在运行Linux CentOS 7的计算机上正确安装luasql .

现在我在Linux Ubuntu 16上遇到了类似的问题.我尝试了以下命令:

sudo apt-get -y install lua-sql-postgres
sudo apt-get -y install lua-sql-postgres-dev
sudo luarocks install luasql-postgres

这是我从系统得到的错误:

Installing https://rocks.moonscript.org/luasql-postgres-2.3.5-2.rockspec...
Using https://rocks.moonscript.org/luasql-postgres-2.3.5-2.rockspec... switching to 'build' mode

Error: Could not find expected file libpq-fe.h, or libpq-fe.h for PGSQL -- you may have to install PGSQL in your system and/or pass PGSQL_DIR or PGSQL_INCDIR to the luarocks command. Example: luarocks install luasql-postgres PGSQL_DIR=/usr/local

有谁知道如何解决这个问题？谢谢

正如@Knud Larsen所建议的那样:

首先,您需要安装libpq-dev.

如果安装成功,则可以看到该文件 /usr/include/postgresql/libpq-fe.h

之后执行命令:

sudo luarocks PGSQL_INCDIR=/usr/include/postgresql/ install luasql-postgres
