我正在制作一個批處理文件，用于從SVN中簽出項目。我要求用戶輸入目錄，當您到達所需的目錄時，鍵入checkout，它將簽出該項目目錄。但是，我在下面的代碼上遇到了一些麻煩。請幫忙。if /i %choice%==1 ( clssvn ls %svnroot_temp%:topset /p direct=Enter directory:if %direct%=checkout( goto :checkout_area )set svnroot_temp= %svnroot_temp%/%direct%svn ls %svnroot_temp%goto :top)我在哪里錯了？

從來沒有使用:label也沒有:: label-like comment封閉在命令塊內部()的括號。證明：
@ECHO %1>NUL
if "" == "" (
@echo a simple echo, no comments
)
if ""=="" (
@echo a rem comment follows this echo command
rem comment
@echo a rem comment precedes this echo command
)
if ""=="" (
@echo a label-like comment follows this echo command
:: comment
@echo a label-like comment precedes this echo command
)
if ""=="" (
@echo a label follows this echo command
:label
@echo a label precedes this echo command
)
輸出：
==>D:\bat\labels.bat OFF
a simple echo, no comments
a rem comment follows this echo command
a rem comment precedes this echo command
a label-like comment follows this echo command
'@echo' is not recognized as an internal or external command,
operable program or batch file.
a label follows this echo command
'@echo' is not recognized as an internal or external command,
operable program or batch file.

如果我可以理解您的目標，那么下一個代碼段應該可以按預期工作：
SETLOCAL enableextensions
rem (set `svnroot_temp` and `choice` variables here)
if /i "%choice%"=="1" (
cls
svn ls %svnroot_temp%
call :top
)
goto :eof
:top
set /p direct=Enter directory:
if /I "%direct%"=="checkout" goto :checkout_area
set "svnroot_temp=%svnroot_temp%\%direct%"
svn ls %svnroot_temp%
goto :top
:checkout_area
請注意，兩個比較表達式if /I "%direct%"=="checkout" goto :checkout_area都用雙引號引起來，因為任何用戶輸入都可能包含空格，甚至可能為空。
不確定要引用svn ls "%svnroot_temp%"。
不確定命令"%svnroot_temp%"的輸入目錄還是輸出目錄svn ls：
如果輸入：if not exist "%svnroot_temp%\%direct%\" goto :top 在更改之前先檢查使用set "svnroot_temp=%svnroot_temp%\%direct%"
萬一輸出：更改MD "%svnroot_temp%" 2>NUL 后使用創建。
