Cargo path setup for rust-racer

Question

I just installed racer using cargo. After installing it say this:

Installing /home/karthik/.cargo/bin/racer
warning: be sure to add `/home/karthik/.cargo/bin` to your PATH to be able to run the installed binaries

How do I do this? Googling didn't help. Also, Should I be setting a PATH variable for cargo bin as well?

Edit: OS is Ubuntu 14.04 and I have super user access

Solution 1

You have to add the cargo bin path to your PATH variable and set the RUST_SRC_PATH in .profile or .bash_profile.

Solution 2

There are two steps:

(1) Add the Cargo bin to your PATH variable. You can run $ whereis cargo to find the bin path, and then do $ sudo -H gedit /etc/environment where you can add that new path section to your current PATH variable. You will need to save and close the file (and you can ignore the error message in the terminal during the saving portion) in order for it to take effect.

(2) Run $ rustup component add rust-src to download the necessary Rust source files for you.

At this point Racer should work properly.
