Batch file 创建一个.bat文件并通过调用运行多个命令

我想在批处理文件中运行一些命令并使用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.
)

当我在npm安装完成后运行此批处理文件时

node js installed
if was unexpected at this time.

如何检查命令的成功与否，然后运行其他命令。

尝试一下：

@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，则运行下一个命令

|

随后将成为

else

操作符
