Could not write to .bash_profile when installing Rust on macOS Sierra

Question

I am trying to install Rust by running the following:

sudo curl https://sh.rustup.rs -sSf | sh

I keep getting this following error:

could not write rcfile file: '/Users/pro/.bash_profile'
info: caused by: Permission denied (os error 13

Answer 1

Give a try using this not using sudo:

curl https://sh.rustup.rs -sSf | sh -s -- --help

If that works then probably you could try:

curl https://sh.rustup.rs -sSf | sh -s -- --no-modify-path 

If the command with the --no-modify-path option works, you'll have to manually update .bash_profile to include it in your path:

source ~/.cargo/env
