1、在 Windows 10 专业版中，PHP 无法运行的排查分析。执行命令：php-cgi.exe -b 127.0.0.1:9000-c C:/php-7.4.27/php.ini ，自动退出。如图1
2、安装 Visual C++ 2015运行库 64位，如图2
3、再次执行命令：php-cgi.exe -b 127.0.0.1:9000-c C:/php-7.4.27/php.ini ，报错：PHP Warning: ‘vcruntime140.dll’ 14.0 is not compatible with this PHP build linked with 14.16 in Unknown on line 0 。如图3

PS C:\php-7.4.27> php-cgi.exe -b 127.0.0.1:9000-c C:/php-7.4.27/php.ini
PHP Warning: 'vcruntime140.dll' 14.0 is not compatible with this PHP build linked with 14.16 in Unknown on line 0
PS C:\php-7.4.27>
4、重启电脑，仍然报同样的错误。参考网址：https://www.shuijingwanwq.com/2019/01/24/3139/ ，VC15 版本需要安装 Visual Studio 2017 x64 或 x86 的 Visual C ++ Redistributable，下载并安装 Microsoft Visual C++ Redistributable for Visual Studio 2017。安装 Visual CPP 2017运行库 64位。不再报错。如图4

5、执行命令：php -v，正确显示 PHP 版本。如图5
