@wojtekmach, which check do we execute here? Maybe we can add the check we run in the error message?

wojtekmach commented 4 months ago

The error is raised here: https://github.com/elixir-lang/elixir/blob/v1.16.2/lib/elixir/scripts/windows_installer/installer.nsi#L119

based on this check:

https://github.com/elixir-lang/elixir/blob/v1.16.2/lib/elixir/scripts/windows_installer/installer.nsi#L94:L96

It looks like you maybe have OTP 25 installed too so consider uninstalling it first. Though the installer should gracefully handle other installation.

@yeshan333 can you try executing the commands above in your Erlang installation? Does it work? What does it return?

yeshan333 commented 4 months ago

After I uninstalled OTP 25, the installer can work normally.

However, if I have multiple OTP versions installed on my machine at the same time, it seems that Elixir's installer cannot find them well.

And OTP 25 installation path exists in the environment variable:

Thank you for checking, this is really helpful. What is the installer version, i.e. Elixir version, you used?

installer version is elixir-otp-25.exe.

wojtekmach commented 3 months ago

That's not enough information, which release (https://github.com/elixir-lang/elixir/releases) did you download the installer from?

@yeshan333 in the meantime you can handle multiple versions using scoop

scoop install erlang@25.3.2.12
scoop install elixir@1.16.2-otp-25
scoop install elixir@1.16.3-otp-25 # becomes the current version
scoop reset elixir@1.16.2-otp-25 # change current version
