我正在运行run rake db:migration命令,终端告诉我rake不是命令
$ heroku run rake db:migrate --app"glacial-lake-5597"
Running `rake db:migrate --appglacial-lake-5597` attached to terminal... up, run.1930
bash: rake: command not found
$ heroku run rake db:migrate
Running `rake db:migrate` attached to terminal... up, run.4588
bash: rake: command not found
我已经将已安装和已提交的更改捆绑到git.
我看了遍布StackOverflow,我找不到答案
有人能指出我正确的方向
