You can use the command line to operate the version management library every day. Svn add path is found, and occasionally an error is prompted as follows: You can see from the error prompt in this prompt, it seems to be a problem with the. svn folder. This folder is a reserved name. Therefore, it cannot be operated. However, such errors do not occur all the time, but occasionally. In most cases, such errors are not prompted. Therefore, you do not need to worry about it. But there is no solution. The solution is as follows. First, you need to move the. svn folder to the upper-level directory. Second, you need to write the name of the submitted file, but it cannot contain the. svn folder. Third, you can directly use the ci Command instead of the add command. In short, svn is sometimes unstable, but it is occasionally compared. Therefore, you can consider how to solve the problem. Hope to help you.
