installer: Error the package path specified was invalid

[mcandre (Andrew Pennebaker)]

I'm trying to install MacPorts v2.4.2 in High Sierra, but I'm getting an error instead.

Trace:

$ curl -o /Users/vagrant/MacPorts-2.4.2-10.13-HighSierra.pkg https://github.com/macports/macports-base/releases/download/v2.4.2/MacPorts-2.4.2-10.13-HighSierra.pkg
$ sudo installer -verbose -pkg /Users/vagrant/MacPorts-2.4.2-10.13-HighSierra.pkg -target /
installer: Error the package path specified was invalid: '/Users/vagrant/MacPorts-2.4.2-10.13-HighSierra.pkg'.

You will have to provide more information that this. Did you check that the download was successful? What's the filesize of the downloaded file? What's its sha256 checksum?

If I download the file, it seems to be parsed just fine:

GitHub redirects the download location. Use the -L flag to curl to tell it to follow that redirect, as Clemens showed.

Confirmed, thank you for the tip! I'm now using -L by default in my curl scripts to ensure that any HTTP redirects are followed. MacPorts now works in my Vagrant box!
