我想使Rails使用Cygwin使用heroku但我遇到问题,当我做
bundle安装我确定postgres已经安装Cygwin的setup.exe但遇到了问题
gem install pg pre>,我不能理解错误消息。
如果这个问题很琐碎, ;这是我第一次尝试学习RoR,错误日志如下:先感谢!

pggem遵循 PostgreSQL的版本控制政策。
I'm trying to get Rails working with Cygwin using heroku but I'm running into problem when I do
bundle installI'm pretty sure postgres is installed (I installed everything with 'postgres' in its title from Cygwin's setup.exe but am running into problems with
gem install pg, and I can't make sense of the error messages.
Apologies if this problem is trivial; it's my first time trying to learn RoR. Error log is below. Thanks in advance!

Version 0.13 of the gem doesn't support versions of PostgreSQL older than 8.3. You'll either need to upgrade your Postgres or install an older gem (e.g., gem install pg -v '< 0.13').
The 'pg' gem follows PostgreSQL's versioning policy.
