bash - 在 Flutter 安装中通过添加路径的名称找到一个交换文件

Question

我正在学习有关 Flutter 开发的在线教程，但我已经被 Flutter 的安装所困扰。

当我尝试将 Flutter 的路径添加到我的计算机(macOS Mojave 10.14.6)时:

vim .bash_profile

我收到了这条消息:

Found a swap file by the name ".bash_profile.swp"
      owned by: username   dated: Wed Jan 15 01:04:29 2020
     file name: ~username/.bash_profile
      modified: YES
     user name: username   host name: name's-Air-2.local.tld
    process ID: 44340
While opening file ".bash_profile"

(1) Another program may be editing the same file.  If this is the case,
be careful not to end up with two different instances of the same
file when making changes.  Quit, or continue with caution.
(2) An edit session for this file crashed.
If this is the case, use ":recover" or "vim -r .bash_profile"
to recover the changes (see ":help recovery").
If you did this already, delete the swap file ".bash_profile.swp"
to avoid this message.

Swap file ".bash_profile.swp" already exists!

按 R R(ecover) 我得到:

Enter number of swap file to use (0 to quit): 

我该如何处理？

其实我不知道这是什么 bash.profile s 代表。

编辑:曾经 D(eleted) .swp文件并重新启动 Flutter 的安装我从 Python(?) 收到了这条消息:

".bash_profile" 46L, 1556C

这个时候我该怎么办？

Answer 1

您可以删除 .swp文件。它只是一个文件，Vim 在保存之前将其更改缓存到其中。您可能之前正在编辑该文件并毫不客气地退出vim，因此无法删除.swp文件关闭前。

您的 .bash_profile是当您打开终端时 bash 读取的文件。这是保存您的 bash 首选项的地方。您在 .bash_profile 中更新 PATH 并在您打开终端时读取该路径。
