VC ++ 2017找不到VC ++工具版本“ 14.16.27023”

Question

我已经安装了Visual 2017 C ++生成工具。我正在尝试运行vsdevcmd来准备环境。但是，我收到一个错误消息，说明实际上没有安装VC ++工具。

以下是我得到的错误：

[DEBUG:vcvars.bat] Could not find VC++ tools version "14.16.27023" under "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\".
[DEBUG:ext\vcvars.bat] init:COMPLETE

[DEBUG:VsDevCmd.bat] --------------------- VS Developer Command Prompt Environment [post-init] ---------------------

这是该特定错误的3级错误报告：

C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC>if exist "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.16.27023\" (
set "VCToolsInstallDir=C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.16.27023\"
 set "VCToolsVersion=14.16.27023"
)  else (
set VCToolsInstallDir=
 if "3" GEQ "2"
 goto :end
)
[DEBUG:vcvars.bat] Could not find VC++ tools version "14.16.27023" under "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\".

该目录存在是因为我复制并粘贴了路径，并且能够更改为该目录。使用资源管理器，我还可以看到确实存在确切的版本，并且其中包含所有预期的工具（如下图所示）

任何想法可能是什么问题？

修改

就像汉斯在评论中指出的那样，文件名14.16.27023的开头有一个通配符。

根据输出，它从此处加载路径：C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC>set "__VCVARS_DEFAULT_CONFIG_FILE=C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Auxiliary\Build\Microsoft.VCToolsVersion.default.txt"

我已经检查了此文件，它包含以下内容（无奇数字符）：

还用十六进制编辑器查看过，那里什么也没有：

我检查了vcdevcmd.bat文件，但此操作失败：

@REM *****************************************************************
@REM This section executes all .bat files found in vsdevcmd\ext.
@REM Any "leaf node" script should be placed in this directory.
@REM A few notes:
@REM * For determinism sake, the scripts are called in alphabetical
@REM   order.
@REM * This section does NOT recursively look in sub-directories
@REM   under vsdevcmd\ext. Sub-directories may be used for
@REM   "implementation detail" scripts called by .bat files in the
@REM   vsdevcmd\ext folder.
@REM *****************************************************************

@REM Iterate through ext scripts
if NOT EXIST "%VS150COMNTOOLS%vsdevcmd\ext\" (
    @echo [ERROR:%~nx0] Cannot find 'ext' folder "%VS150COMNTOOLS%vsdevcmd\ext\"
    set /A __vscmd_vsdevcmd_errcount=__vscmd_vsdevcmd_errcount+1
    goto :ext_end
)

for /F %%a in ( 'dir "%VS150COMNTOOLS%vsdevcmd\ext\*.bat" /b /a-d-h /on' ) do (
    call :call_script_helper ext\%%a
)

:ext_end
set __vscmd_dir_cmd_opt=
exit /B 0

出现错误：

'"C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\Common7\Tools\vsdevcmd\ext\"' is not recognized as an internal or external command,
operable program or batch file.
[ERROR:ext\] init:FAILED code:1

现在，我什至不确定这两个错误是否相关，但都出现在日志中。我试图完全删除VS及其所有产品。我已经重新安装了全新的安装程序，无济于事。

是的，我最初有这个工作。

编辑2

好的，这是无法加载VC ++工具（从vcvars.bat开始）的问题：

:export_env_vctoolsinstalldir
if exist "%VCINSTALLDIR%Tools\MSVC\%__VCVARS_TOOLS_VERSION%\" (
    set "VCToolsInstallDir=%VCINSTALLDIR%Tools\MSVC\%__VCVARS_TOOLS_VERSION%\"
    set "VCToolsVersion=%__VCVARS_TOOLS_VERSION%"
) else (
    set VCToolsInstallDir=
    if "%VSCMD_DEBUG%" GEQ "2" @echo [DEBUG:%~nx0] Could not find VC++ tools version "%__VCVARS_TOOLS_VERSION%" under "%VCINSTALLDIR%Tools\MSVC\".
    goto :end
)

我找不到任何环境。为__VCVARS_TOOLS_VERSION或VCVARS_TOOLS_VERSION设置的变量。如果我可以设置它，也许我可以使它正常工作。

在同一文件的开头找到了该文件：

if "%__VCVARS_VERSION%" NEQ "" (
    set __VCVARS_TOOLS_VERSION=%__VCVARS_VERSION%
    goto :export_env_vctoolsinstalldir
)

我尝试设置该变量并重新运行vcdevcmd，但仍然失败：

set __VCVARS_VERSION=14.16.27023

也尝试过：

vsdevcmd -arch=amd64 -host_arch=amd64 -vcvars_ver=14.16.27023

产生错误：
