Does cargo install have an equivalent update command?
RustRust CargoRust Problem Overview
I'd like to update a package that I used cargo install
to globally install packages, such as rustfmt or racer. I can't find a way to update an installed package without first deleting it (via cargo uninstall
) and then running the install command again. Is there an update command?
Rust Solutions
Solution 1 - Rust
There is no such command in vanilla cargo
(well, there's cargo install
but that's for dependencies), but since cargo
supports third-party subcommands there is an answer: the cargo-update
crate.
Install as usual with cargo install cargo-update
, then use cargo install-update -a
to update all installed packages, for more usage information and examples see the cargo install-update
manpage.

Solution 2 - Rust
As of Rust 1.41.0, you can use the following command to update crates to their latest version:
cargo install <crate>
This came from pull request #6798 (Add install-upgrade) and was stabilized in #7560 (Stabilize install-upgrade).
How does it work?
Instead of failing when cargo install
detects a package is already installed, it will upgrade if the versions don't match, or do nothing (exit 0) if it is considered "up-to-date".
Forcing an upgrade / re-installation
The following command will always uninstall, download and compile the latest version of the crate - even if there's no newer version available. Under normal circumstances the install-upgrade
feature should be preferred as it does save time and bandwidth if there's no new version of the crate.
cargo install --force <crate>
Documentation
Further information can be found in the GitHub issue rust-lang/cargo#6797 and in the official documentation chapter.
Solution 3 - Rust
A solution I've found is to add the --force
flag to the install command. For example cargo install --force clippy
. This will effectively re-install the latest version.
Solution 4 - Rust
Here is a one-liner to update all installed Cargo crates, except those installed from a local folder:
cargo install $(cargo install --list | egrep '^[a-z0-9_-]+ v[0-9.]+:$' | cut -f1 -d' ')
Explanation:
- List installed packages
- Filter to lines which contain package names and versions, and exclude ones with filesystem paths
- Cut those lines to only include the package name
cargo install
with the resulting package names
