Script blt blt:init:shell-alias -y --ansi handling the blt-alias event returned with error code 255

[mktomanikandan]

My system information:

• Operating system type: [Centos]
• Operating system version: [7]
• BLT version: [9.2.1]

Output of blt doctor:

When I run this command: composer run-script blt-alias

[replace with command, add -vvv for very very verbose output.]

I get the following output:
blt blt:init:shell-alias -y --ansi
PHP Fatal error: Uncaught Error: Call to undefined function Acquia\Blt\Robo\Inspector\posix_getpwuid() in /var/www/html/clean-harbors-cms/vendor/acquia/blt/src/Robo/Inspector/Inspector.php:487

[replace with ENTIRE command output. DO NOT enter partial output.]

And I expected this to happen:

@mktomanikandan can you give me any details on where you are running this command?
can you please post the results of blt doctor?

i am running blt 9.2.1 locally and cannot reproduce the above inside or outside my vm. it seems to work regardless for me.

also, are you by chance running on windows? i see a similar ticket in our issue queue here - #2526
