使 rustc、cargo、rustup、rustdoc 命令在 Linux 的 Windows 子系统中无需 sudo 即可工作

Question

I'm running a WSL Debian distro because I wanted to follow along with the InterMezzOS tutorials. I followed the installation instructions for Rust and ran curl https://sh.rustup.rs -sSf | sh curl https://sh.rustup.rs -sSf | sh , but I can only make the rustc command available by running source $HOME/.cargo/env AFTER running sudo su , and when I exit sudo I can't call it, and when I retype sudo su it doesn't work anymore, I have to type it again.

Is there any way I can make it available so the commands work every time I open my shell, without running sudo every time?

Answer 1

Right after you install Rust, you can find where it was installed in the Linux filesystem by running whereis rustc

It should output something like this:

rustc: /home/damianrivas/.cargo/bin/rustc

You need to add that to your path, so open up .bashrc in an editor

nano ~/.bashrc

(if you use zsh like I do just replace it with ~/.zshrc )

Scroll down to the bottom of the file (or use the keyboard shortcut alt + / , and add Rust's location to PATH by adding this at the end:

# Add Rust to $PATH
export PATH="$HOME/.cargo/bin:$PATH"

I have $HOME because /home/damianrivas/ is my $HOME path. I could've also put

export PATH="/home/damianrivas/.cargo/bin:$PATH"

After this is done, exit all of your open WSL terminals before opening up a new one. You can restart your PC to be sure. Then run rustc --version when you open up a new terminal and it should work.

Notice that curl https://sh.rustup.rs -sSf | sh curl https://sh.rustup.rs -sSf | sh will add to /home/<user>/.profile a line that appends binaries in ~/.cargo/bin , including rustup and rustc. The addition of the binaries in .cargo however does not take immediate effect. An easy way to associate it with your bash terminal is (immediately after installation):

echo $(cat ~/.profile | tail -1) >> ~/.bashrc
source ~/.bashrc

In your particular case, since you are root, you should copy /root/home/.cargo and /root/home/.profile into your own users home directory.

Following their documentation I do this:

$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

...


Current installation options:


   default host triple: aarch64-unknown-linux-gnu
     default toolchain: stable (default)
               profile: default
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation


< I enter 1>

Then the installation completes with this:

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, run:
source $HOME/.cargo/env

So I do the following

• You may have to replace ~.bashrc with ~/.zshrc or something similar.

echo "export PATH='\$HOME/.cargo/bin:\$PATH'" >> ~/.bashrc"
source ~/.bashrc

And I check if rust is installed

$ whereis rustc
rustc: /usr/bin/rustc /usr/share/rustc /home/nvidia/.cargo/bin/rustc

$ which rustc
/home/nvidia/.cargo/bin/rustc

$ rustc --version
rustc 1.53.0 (53cb7b09b 2021-06-17)

This looks good, but now let's check out sudo so that system scripts can run without issues.

$ sudo whereis rustc
rustc:

$ sudo rustc --version
sudo: rustc: command not found

OMG! And this is how to fix it

$ sudo apt-get install -y rustc

$ sudo rustc --version
rustc 1.47.0

This worked for me:

#For Mac and Linux Users
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

#window users
Download rustup-init.exe from www.rustup.rs and run.

Note:#run this after
source $HOME/.cargo/env

To verify the current Rust version, use the rustc --version or rustc -V command.
