Getting error: could not compile `postgresql_archive` (lib) due to 23 previous errors in Windows

[manuelarte]

I am getting:

error: could not compile postgresql_archive (lib) due to 23 previous errors

When I try to run my code in Windows
Cargo.toml

...
[dev-dependencies]
postgresql_embedded = "0.16.1"

as a github action it works, but not in my Windows machine, any idea?

[brianheineman]

@manuelarte could you provide the "23 previous errors" that were reported? Also, which version of Rust are you using? This project was recently updated to use features in Rust 1.80; so if you are using an older version of rust you might want to either try version 0.14.2 of this project, or upgrade your version of Rust to the latest.

Hi @brianheineman , all of them are related to lazy_cell feature:

error: aborting due to 23 previous errors

[brianheineman]

@manuelarte in order to address those errors, you will need to use Rust >= 1.80 or use version 0.14.2 of the library.

[manuelarte]

@brianheineman I forgot that part, sorry, I was using 1.79, I updated to 1.80, and it works. Thanks!
