Installing with script from website does not work directly

I know this isn't technically Deno CLI, but it's the closest related tag I could find.

I used the install script from deno.com today:

curl -fsSL https://deno.land/install.sh | sh

curl -fsSL https://deno.land/install.sh | sh

It results in an error

mkdir: /home/<username>: Operation not supported

mkdir: /home/<username>: Operation not supported

I was able to install it by specifying the

DENO_INSTALL

DENO_INSTALL

variable as

/Users/<username>/.deno

/Users/<username>/.deno

.

I don't need help anymore, but I would expect this to work without needing to specify anything on Mac.
