我使用git从rails应用程序中删除了一些文件。他们被承诺并被推到Heroku(现场)。现在，我想把他们中的一些带回来，但我做起来有困难。我一直在使用git一段时间，不确定我做错了什么。我已经检查了几个git页面，以确保这应该工作。
文件不在我的本地存储库中，而是在git中。Git列出了它们(在我的例子中显示了一个)，但不让我检索它们。
我找到了提交，下面显示了记录的提交中的文件:
jdc44@jdc44-Kudu:~/Websites/myapp$ git diff-tree --no-commit-id --name-only -r 9c88a26ade871
...
app/models/fitness/weight.rb
...
试图恢复权重。rb文件:
jdc44@jdc44-Kudu:~/Websites/myapp$ git checkout 9c88a26ade871 -- app/models/fitness/weight.rb
error: pathspec 'app/models/fitness/weight.rb' did not match any file(s) known to git
试着看看我是否可以显示文件:
jdc44@jdc44-Kudu:~/Websites/myapp$ git show 9c88a26ade871:app/models/fitness/weight.rb
fatal: Path 'app/models/fitness/weight.rb' does not exist in '9c88a26ade871'
jdc44@jdc44-Kudu:~/Websites/myapp$ git diff-tree -r 9c88a26ade871

Git中的每次提交都是当时所有文件的完整快照。9c88a26ade871没有app/models/fitness/weight文件。因为这是你删除它的提交。
您需要在删除它之前从commit获取它。9 c88a26ade871 ^。看到gitrevisions。
git checkout 9c88a26ade871^ -- app/models/fitness/weight.rb
或者使用更简单的git restore(签出分为恢复和切换)。
git restore --source 9c88a26ade871^ app/models/fitness/weight.rb
