部署新服务器之后发现，服务器上没有console命令了

You can specify extra command-line arguments to be used every time 'rails new' runs in the .railsrc configuration file in your home directory. Note that the arguments specified in the .railsrc file don't affect the defaults values shown above in this help message. Example: rails new ~/Code/Ruby/weblog This generates a skeletal Rails installation in ~/Code/Ruby/weblog. See the README in the newly created application to get going.
看了一下文件发现bin目录有个软链接，

先删除了链接
# rm bin
然后再新建个文件夹重新生成一下目录的内容就ok啦
root@i-1lb6pxls:/home/ubuntu/campo/current# mkdir bin root@i-1lb6pxls:/home/ubuntu/campo/current# rake rails:update:bin exist bin create bin/bundle create bin/rails create bin/rake
如果记不清rake命令了可以查一下

接下来就可以运行console啦
