原因在于你当前库，已经把一些想要忽略的文件诸如 .Rproj.user\C1821C3F\pcs\windowlayoutstate.pper 加入到版本管理了，然后你再配置修改 .gitignore 配置并不能对已经纳入版本管理的文件进行忽略，现在配置的 .gitignore 只能保证新的符合配置规则的文件不会被纳入版本管理中。所以解决办法很简单，把已经纳入版本管理的想要 ignore 的文件移出版本管理，命令：git rm --cached <file> git rm -r --cached <folder>。

    G_will 感谢回复！我对本地文件D:\04_Rrender\Blogdown\MyBlog中进行Git Bash Here后，在界面中先后输入了您提供的两个命令，但是都报错了，具体情况如下：

    $ git rm --cached <file>
bash: syntax error near unexpected token `newline'

    后来查资料才知道是<>的问题，我想我理解错了你的意思，<file>应该是写具体的文件名字，而不是照写。然后根据这篇帖子，我了解到如果没指定清楚文件，可能会把整个仓库的缓存删除干净。

    所以还想请教一下您，我是应该在<file>指定.gitignore文件，然后在<floder>指定.Rproj.user吗？

    .gitignore的源代码位置：https://github.com/residualsun1/MyBlog/blob/main/.gitignore

    .Rproj.user的源代码位置：https://github.com/residualsun1/MyBlog/tree/main/.Rproj.user

        residual-sun 所以还想请教一下您，我是应该在<file>指定.gitignore文件，然后在<floder>指定.Rproj.user吗？

        <file> 和 <folder> 是写你不想让 git 记录的文件/目录。

        git rm -r --cached .Rproj.user

        git rm 删除后文件还在仓库，git checkout 12afd99 这样就变回来了。

        要完全删掉文件，可以看这篇文章：完全删除 Git 仓库的文件

            CyrusYip 感谢回复！我在Git Bash运行了以下命令：

            git rm -r --cached .Rproj.user

            下一步是要传到Github上吗？如果是的话是用哪个命令？因为我平时主要用GitHub Desktop来修改和上传文件的，所以不大清楚。

                我运行了以下两个命令：

                git add .
git commit -m 'delete'

                响应结果如下：

                不知道和你提供的代码效果是否是一样的。

                    一些建议：

                    1. 用英文在谷歌搜技术问题，我刚在谷歌搜 .Rproj.user .gitignore，我这边第三个结果就是你的问题。

                      https://stackoverflow.com/questions/36185456/gitignored-files-still-shown-in-rstudio

                    2. 别看 CSDN。它质量不行，抄袭和垃圾内容太多，又要登陆才让复制代码，还有广告。

                    3. 小心内容农场。

                      你看这句话就狗屁不通，提交里怎么会有垃圾邮件。看到这句话就可以关掉这个网页了。

                    为什么中文互联网那么多垃圾内容！叹气。

                      CyrusYip
                      好！

                      我过去一直都是用CSDN搜索问题……广告确实很多。我偶尔也会在chrome上搜索，用中文搜也能搜到英文答案，例如GitHub里的、Posit community里的，也包括叶大哥你发的stackoverflow。

                      忏愧的是，我更多时候会纵容自己的惰性，倾向于看中文的答案，知乎和CSDN就很现成，就是答案质量往往不如耐心看下来的英文帖子。

                      十分乐意采纳你的意见！
