Can't build example diesel_embedded

[tylerjw]

What steps will reproduce the bug? (please provide code snippet if relevant)

1. copy the example code out of diesel_embedded
2. fixup the Cargo.toml to build outside the workspace with current versions

[package]
name = "diesel_embedded_test"
edition = "2021"
version = "0.6.0"

[dependencies]
diesel = { version = "2.2.4", features = ["postgres", "r2d2"] }
diesel_migrations = { version = "2.2.0", features = ["postgres"] }
postgresql_embedded = { version = "0.17" }
r2d2_postgres = "0.18.1"
tokio = { version = "1.41.0", features = ["full"] }

4. build failures

Hello @tylerjw, thank you for reporting the issue. I was able to reproduce this with version 0.17.2. Version 0.17.3 was just released and appears to address the issue.

Sweet, thank you! Odd question, I wasn't able to figure it out through your docs. Is there a way I can specify a local path for using this in an environment where I don't have access to the internet?

You might want to take a look at Settings.installation_dir (https://github.com/theseus-rs/postgresql-embedded/blob/main/postgresql_embedded/src/settings.rs#L42-L43). The installation_dir is the path prefix without the PostgreSQL version number where the installation is located. For instance if you set the installation_dir to /foo and the version to 17.0.1, and you manually installed PostgreSQL to /foo/17.0.1 I would expect that it would work without an internet connection.
