升级 Postgres 后,当我尝试迁移数据库时出现以下错误。
enable_extension(:postgis)
SQL (17.2ms) CREATE EXTENSION IF NOT EXISTS "postgis"
PG::UndefinedFile: ERROR: could not open extension control file "/usr/local/Cellar/postgresql/9.4.5/share/postgresql/extension/postgis.control": No such file or directory
: CREATE EXTENSION IF NOT EXISTS "postgis"
(0.3ms) ROLLBACK
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

不确定从哪里开始。大多数其他问题似乎与 Linux 有关,当我尝试创建符号链接(symbolic link)时它也没有工作。
最佳答案
你应该安装 postgresql-9.4-postgis-2.1
关于ruby-on-rails - PG::UndefinedFile: 错误:无法打开扩展控制文件,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/33314381/
