What operating system do you have? It seems like your `read` command does not support the `-n` argument - but that's not the point, I really need to work on removing installation friction.
If you have git and cargo installed (needed anyway), you can try:
# project structure
cd ~
mkdir .aspen
cd .aspen
mkdir bin
# download
git clone https://github.com/vrtbl/passerine
git clone https://github.com/vrtbl/aspen
# build
cd aspen
cargo build --release
mv target/release/aspen bin
# source
echo "export PATH="~/.aspen/bin:$PATH" >> ~/.profile
Restart your shell, and it should work. Type `aspen` and hit enter and see if you get a help message with version 0.4.0. If you have any more issues, reach out on the Discord server so we can reach a more permanent solution (if you haven't already).
