我正在关注最近关于设置 PostgreSQL 的 RailsCast，但我无法运行 initdb/usr/local/var/postgres 命令。每次运行它时，我都会收到此错误:
The files belonging to this database system will be owned by user "Construct".
This user must also own the server process.
The database cluster will be initialized with locale en_US.UTF-8.
The default database encoding has accordingly been set to UTF8.
The default text search configuration will be set to "english".
creating directory /usr/local/var/postgres ... initdb: could not create directory "/usr/local/var": Permission denied
最佳答案
这应该可以正常工作:
# sudo mkdir /usr/local/var/postgres
# sudo chmod 775 /usr/local/var/postgres
# sudo chown construct /usr/local/var/postgres
# initdb /usr/local/var/postgres
使用您的用户名代替构造。因此，如果您的计算机用户名是 WDurant，则代码将是:
# sudo chown $(whoami) /usr/local/var/postgres
关于database - 尝试在我的环境中设置 Postgres，但似乎无法获得对 intidb 的权限，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10431426/
