Intellij IDEA 启动时，弹出Can't start Git问题解决办法

现象说明

今天打开idea，突然在右下方弹出提示框如下：

Can't start Git: /usr/bin/git
Probably the path to Git executable is not valid.

问题出现的原因

为了找到问题出现的原因，首先需要打开终端确认一下是否可以执行git命令：

sudo /usr/bin/git

出现如下结果：

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

但是如果执行如下命令，出现的结果却不一样：

cd /usr/bin/
git

执行的结果如下：

usage: git [--version] [--help] [-C ] [-c name=value]
           [--exec-path[=]] [--html-path] [--man-path] [--info-path]
           [-p | --paginate | --no-pager] [--no-replace-objects] [--bare]
           [--git-dir=] [--work-tree=] [--namespace=]
            []

These are common Git commands used in various situations:

start a working area (see also: git help tutorial)
   clone      Clone a repository into a new directory
   init       Create an empty Git repository or reinitialize an existing one

work on the current change (see also: git help everyday)
   add        Add file contents to the index
   mv         Move or rename a file, a directory, or a symlink
   reset      Reset current HEAD to the specified state
   rm         Remove files from the working tree and from the index

examine the history and state (see also: git help revisions)
   bisect     Use binary search to find the commit that introduced a bug
   grep       Print lines matching a pattern
   log        Show commit logs
   show       Show various types of objects
   status     Show the working tree status

grow, mark and tweak your common history
   branch     List, create, or delete branches
   checkout   Switch branches or restore working tree files
   commit     Record changes to the repository
   diff       Show changes between commits, commit and working tree, etc
   merge      Join two or more development histories together
   rebase     Reapply commits on top of another base tip
   tag        Create, list, delete or verify a tag object signed with GPG

collaborate (see also: git help workflows)
   fetch      Download objects and refs from another repository
   pull       Fetch from and integrate with another repository or a local branch
   push       Update remote refs along with associated objects

'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help ' or 'git help '
to read about a specific subcommand or concept.

以上结果证明在目录内执行git命令是没有问题的, 可能是由于xcode问题造成的。

解决方案

可在终端中执行如下命令：

xcode-select --install

系统弹出xcode插件下载的界面，大概2分钟安装完毕。

至此，问题已经得到解决。
