Answer 1

Super late to this response but none of the above solutions worked out for me. I found a fix though!

I am on macOS Catalina. For some bizarre reason, it turned out to be a decompression/unpack issue with the .tgz file from Observable's website. I use an application called The Unarchiver to decompress files, but in this case, the .tgz file did not properly unpack. There was a folder and file missing compared to a friend's computer not using the same program.

Solution: I unpacked .tgz without a third party program – just used macOS (simply double clicking on the file). Then, I loaded the page locally and it worked!

If double clicking on the file fails to unpack, try running tar -xzf filename.tgz in Terminal.
