创建一个 .bat 文件和 运行 多个调用命令

create a .bat file and run multiple command with call

我想运行批处理文件中的一些命令并使用 if 语句。

@echo off
call npm install
echo node js instaled
if not errorlevel 1 (
    call composer install
    if not errorlevel 1 (
        echo commands run success.
    ) else (
        echo please install composer and then run this batch again.
    )
) else (
    echo you have not nodejs in your system. please install nodejs.
)

当我 运行 这个批处理文件在 npm 安装完成后说

node js installed
if was unexpected at this time.

我如何检查命令是否成功,然后 运行 其他命令。

试一试:

@echo off
call npm install && (
    echo node js installed
    call composer install && (
       echo Composer installed
    ) || echo composer install failed
) || echo Nodejs install failed

&&是有条件的,如果第一个命令成功,那么运行下一个。 || 将成为 else 运算符。
