Create a site

What issue or error are you experiencing?

I downloaded localWP, however I cannot create a site (under masOS Monterey 12.6), I get the message “Uh-oh! Unable to provision site.Error: Error: spawn Unknown system error -86
at ChildProcess.spawn (node:internal/
at spawn (node:child_process:783:9)

Security Reminder
Local does a pretty good job of scrubbing private info from the logs and the errors it produces, however there’s always the possibility that something private can come through. Because these are public forums, always review the screenshots you are sharing to make sure there isn’t private info like passwords being displayed.

Hi @Lau

Are you on the Apple Silicon version of Local?

Yes ! I made this adjustment !

For the Apple Silicon version you’ll need to install Rosetta:

usr/sbin/softwareupdate --install-rosetta should do the trick inside your terminal window.

Great, thank you !!
But I thought 2020 Macs with M1 chip already had rosetta? Can I check it somewhere?

I don’t believe it comes installed already since it’s actually for Macs with an Intel processor, but for certain programs like Local Rosetta 2 is required due to the Nginx and MySQL Lighting Services compiled on the Intel architecture.

Thank you for your reply !
However, I’m surprised because when in Finder I select the local application and navigate to file/reading information, I see type=Application (Apple chip) and not type=Application (Intel) ! Wouldn’t that mean that locals would support M1 architecture? (If this is the case he would not need Rosetta and the problem would come from elsewhere…?)
Thank you in advance for your answer

The original error you shared is one we typically see with users who are on Apple Silicon, and download the Apple Silicon version of Local, but don’t have Rosetta 2.

As mentioned previously, Rosetta 2 is required for Local’s Apple Silicon build due to the Nginx and MySQL Lighting Services compiled on the Intel architecture.

OK, thank you very much for your explanation. I will install Rosetta 2 as you explained to me, I will keep you informed of the result :wink:

Thank you very much @Nick-B for your help, everything is fine now, I managed to create a new site, I’m very happy because I was stuck for some time with this problem! THANKS !!! :grin:
