如何在Linux Ubuntu 16上安装luasql?

How to install luasql on Linux Ubuntu 16?

感谢 Whosebug 社区的帮助,我能够在 .

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


请安装包 libpq-dev :

文件 libpq-fe.h/usr/include/postgresql/ http://packages.ubuntu.com/xenial-updates/amd64/libpq-dev/filelist

正如@Knud Larsen 所建议的:

首先,您需要安装libpq-dev

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

之后执行命令:

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