ruby - 每当我输入 `missing postgres.yml` 时，Rails 不会加载默认项目模板，说 `rails new` 文件

Question

每当我尝试使用 rails new -d postgresql -T 开始一个新项目时，它都会给我一个不完整的默认项目并告诉我我缺少 config/databases/postgresql.yml 据我所知，它本来就不应该存在。

有没有人遇到过这个问题或知道我可以尝试解决冲突的一些事情？下面是我尝试创建一个新项目的结果。我可以导航到模板所在的文件夹，但我不知道在那里做任何事情是否有帮助。

我尝试删除 .railsrc 并重新启动计算机。我还确保我的 gemfile 有 gem pg 而我的 databse.yml 没有 username 并且我的适配器正确设置为 adapter :postgresql 。不过，该项目只给了我一个不完整的入门模板，其中包括:

app 
bin 
config 
config.ru 
Gemfile 
Rakefile 
README.rdoc

摆脱标志 -d postgresql -T 并在 Gemfile 中手动将数据库更改为 postgresql。可以找到这样做的说明 here
