'The define key "process.env.ProgramFiles(x86)" contains invalid identifier "ProgramFiles(x86)"'

I'm running into the same issue on Alma Linux:

$ pnpm build

After grepping through the code, I couldn't find the problematic which function. Checking my environment, it appears my system has a weird "which" function defined:

]$ env | grep -i which
which_declare=declare -f
BASH_FUNC_which%%=() {  ( alias;
 eval ${which_declare} ) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot $@

]$ which which
which ()
{
    ( alias;
    eval ${which_declare} ) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot $@
}

After unsetting the variable, I was able to run the build and I came up with a different error now.

✘ [ERROR] Could not resolve "../utils/MessageInterface"

You might have a weird environment variable that is causing a similar error. The MessageInterface is supposed to be a class defined in the example code, so I am going to dig around some more and will post if I find a solution.

--- edit I had moved the index.html and index.ts from the sample code to try to put my own page up, that's why it couldn't find the class. Everything built properly once I put it back.
