MacOS源.bash_profile导致重复消息打印

Question

我在终端中使用source .bash_profile时遇到问题。它打印许多相同的消息是这样的：

-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 
-bash: /Users/wuyiqing: is a directory 

当我重新打开终端，相同的重复消息再次打印：

export PATH=${PATH}:/usr/local/mysql/bin export PATH=$PATH:/Users/keso/Library/Tomcat/bin ~ ~ ~

我试图解决这个问题，但失败了。我怎么能让重复消息消失？

您的.bash_profile中的~行会导致该错误消息。 ~是您的主文件夹路径的外壳缩写，因此这些行扩展为/Users/wuyiqing。因为这是第一件事，所以它被视为执行的命令，但它不是命令，而是目录，所以你会看到“/ Users/wuyiqing：是一个目录”的消息。

有一件事让我感到困惑：根据您发布的内容，.bash_profile包含三条~行，但您将其看作错误消息的十六次。你发布了完整的.bash_profile吗？无论如何，解决方案很简单：删除这些行。
