货箱未添加到路径（鱼 shell）

Question

I'm using the fish shell under MacOS X Capitan and after using rustup.rs I get the following message:

Rust is installed now. Great!

To get started you need Cargo's bin directory in your PATH environment variable. Next time you log in this will be done automatically. The next time I logged in Cargo was not in my PATH. I had to add it manually.

In my.config/fish/fish.config file I have a:

set -x PATH...

line where I had to manually add cargo bin's:

set -x PATH... .cargo/bin

Answer 1

1. run the fish_add_path command

fish_add_path /home/your-username/.cargo/bin/

my path: fish_add_path /Users/aharo/.cargo/bin/

2. restart terminal/shell
3. Run rustc

Answer 2

Follow the steps

1. Open file ~/.config/fish/config.fish ;
2. Add the line set PATH $PATH ~/.cargo/bin ; and
3. Restart fish terminal
