Git:将本地分支与远程暂存和生产进行比较

Question

我在比较本地 master(与 origin/master 相同的提交)和 production/master 时遇到了问题。

$ git remote -v
origin  git@github.com:mydomain/mydomain.git (fetch)
origin  git@github.com:mydomain/mydomain.git (push)
production  git@heroku.com:mydomain-production.git (fetch)
production  git@heroku.com:mydomain-production.git (push)
staging git@heroku.com:mydomain-staging.git (fetch)
staging git@heroku.com:mydomain-staging.git (push)

我似乎能够通过 staging/master 获得差异，但我在使用 production/master 时出现错误:

$ git diff staging/master
[i'm shown diff]
$ git diff production/master
fatal: ambiguous argument 'production/master': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

有人看到我搞砸了吗？

我真正想做的是使用 git diff production/master...master 查看本地主机上的提交，而不是其他远程主机上的提交，但这会产生相同的错误:

$ git diff production/master...master
fatal: ambiguous argument 'production/master...master': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

我以前用过的是

git fetch production master && git diff master production/master

您以前可能从未从那个远程获取数据。

就查看不在 production/master 上但在本地 master 上的提交而言，git log 可能更好适合:

git log --oneline production/master..master
