<div dir="ltr">Hi Junhwan,<div><br></div><div>We use shasum to calculate hashes of the packages the install script downloads from <a href="http://yt-project.org">yt-project.org</a>. This ensures we do not try to unpack and install corrupted downloads.</div>
<div><br></div><div>The issue you're running into is that Apple did not ship the shasum binary on OS X 10.5, although it is available on 10.6 and newer. According to this (<a href="http://stackoverflow.com/questions/7500691/rvm-sha256sum-nor-shasum-found">http://stackoverflow.com/questions/7500691/rvm-sha256sum-nor-shasum-found</a>) StackOverflow discussion, you should be able to work around this issue by temporarily defining a sha512sum function:</div>
<div><br></div><div>function sha512sum() { openssl sha512 "$@" | awk '{print $2}'; }<br></div><div><br></div><div>You'll need to add this as a line in your .bash_profile, I believe. Note that I haven't tested this so there may be issues.</div>
<div><br></div><div>Also, 10.5 is nearly six years old at this point. Many software packages only support 10.6 or newer. It may be a good idea to consider updating to Snow Leopard, which is only $20.00.</div><div><br></div>
