Reticulate fails with uv 0.8.0

[dfalbel]

After installing uv 0.8.0, we see:

> reticulate::py_config()
Error : could not find a Python environment for /
In addition: Warning message:
In normalizePath(python_home) :
  path[1]="/Users/dfalbel/.cache/uv/builds-v0/.tmpeNA4CT/bin": No such file or directory
Error:

When reticulate uses uv to create an ephemeral environment.

The development version of reticulate has a hotfix:

# install.packages("pak")
pak::pak("rstudio/reticulate")

[t-kalinowski]

I did a quick release to CRAN with this hotfix, since this issue affects so many users and workflows. This hotfix only pins the uv version. We'll follow up with a proper fix that supports uv <=0.8.0 in the subsequent release.

#1813

Should this be picked up soon given the recent uv security advisory GHSA-w476-p2h3-79g9 ?

[t-kalinowski]

We restored support for uv versions >= 0.8 in #1818
