Text editors require the rust-analyzer binary to be in $PATH. You can download pre-built binaries from the releases page. You will need to uncompress and rename the binary for your platform, e.g. from rust-analyzer-aarch64-apple-darwin.gz on Mac OS to rust-analyzer, make it executable, then move it into a directory in your $PATH.
On Linux to install the rust-analyzer binary into ~/.local/bin, these commands should work:
$ mkdir -p ~/.local/bin $ curl -L https://github.com/rust-lang/rust-analyzer/releases/latest/download/rust-analyzer-x86_64-unknown-linux-gnu.gz | gunzip -c - > ~/.local/bin/rust-analyzer $ chmod +x ~/.local/bin/rust-analyzer
Make sure that ~/.local/bin is listed in the $PATH variable and use the appropriate URL if you’re not on a x86-64 system.
You don’t have to use ~/.local/bin, any other path like ~/.cargo/bin or /usr/local/bin will work just as well.
Alternatively, you can install it from source using the command below. You’ll need the latest stable version of the Rust toolchain.
$ git clone https://github.com/rust-lang/rust-analyzer.git && cd rust-analyzer $ cargo xtask install --server
If your editor can’t find the binary even though the binary is on your $PATH, the likely explanation is that it doesn’t see the same $PATH as the shell, see this issue. On Unix, running the editor from a shell or changing the .desktop file to set the environment should help.
rust-analyzer is available in rustup:
$ rustup component add rust-analyzer
The rust-analyzer binary can be installed from the repos or AUR (Arch User Repository):
rust-analyzer (built from latest tagged source)
rust-analyzer-git (latest Git version)
Install it with pacman, for example:
$ pacman -S rust-analyzer
rust-analyzer is installed when the rust-analyzer use flag is set for dev-lang/rust or dev-lang/rust-bin. You also need to set the rust-src use flag.
The rust-analyzer binary can be installed via Homebrew.
$ brew install rust-analyzer
It is recommended to install the latest Microsoft Visual C++ Redistributable prior to installation. Download links can be found here.
