PostgreSQL 11.4 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 9.1.1 20190503 (R但是它没有pgcrypto模块:ERROR: could not open extension control file "/usr/pgsql-11/share/extension/pgcrypto.c
我将这个gem添加到Gemfile中,并在database.yml中将适配器名称更改为pgcrypto。并在包安装后执行以下命令。rails generate pgcrypto:install。但是我得到了以下错误,Could not load the 'pgcrypto' Active Record adapter.
