When trying to build a hugo site with modules, hugo fails to get modules, because it can’t run go tool.  
go and hugo was installed using asdf ([https://asdf-vm.com/](https://asdf-vm.com/)). go is working fine from any terminal configuration I tried.  
Has anyone experienced using hugo with asdf?

```auto
❯ hugo mod get -u
unknown command: go. Perhaps you have to reshim?

I suspect this is caused by Hugo’s [security policy](https://gohugo.io/about/security-model/#security-policy), specifically `security.exec.osEnv`.

The default value is:

```nohighlight
[security.exec]
osEnv = ['(?i)^((HTTPS?|NO)_PROXY|PATH(EXT)?|APPDATA|TE?MP|TERM)$']

```

In your site configuration, change this to:

```nohighlight
[security.exec]
osEnv = ['(?i)^((HTTPS?|NO)_PROXY|PATH(EXT)?|APPDATA|TE?MP|TERM|HOME|ASDF_DIR)$']

```

If that doesn’t work, change it to:

```nohighlight
[security.exec]
osEnv = ['.*']

```

See [https://github.com/gohugoio/hugo/issues/9811](https://github.com/gohugoio/hugo/issues/9811)

Adding the asdf path worked. Thank you!
