Question
I used cargo install to globally install a package such as rustfmt or racer.
How can I update an installed package without first deleting it with cargo uninstall and then running cargo install again?
Is there an update command for cargo install?
Short Answer
By the end of this page, you will understand how Cargo handles globally installed binaries, whether cargo install has a built-in update workflow, and the practical commands Rust developers use to reinstall or refresh command-line tools.
Concept
Cargo's install command is used to compile and place a Rust binary crate into your Cargo bin directory, usually something like ~/.cargo/bin. This is commonly used for command-line tools.
The key idea is that globally installed Cargo binaries are not managed in the same way as project dependencies.
For example:
- Project dependencies are tracked in
Cargo.tomlandCargo.lock - Installed tools are just binaries placed on your system
- Cargo does not treat them like a full package manager with automatic upgrade tracking
So the important concept behind this question is:
cargo installinstalls a binary crate- updating usually means reinstalling a newer version over the old one
- in practice, developers often use the same install command again, sometimes with flags such as
--force
Why this matters:
- You will often install developer tools this way
- You need to know whether a command upgrades in place or only installs once
- Using the right command avoids confusion when a tool appears "stuck" on an old version
Also note that some tools in the Rust ecosystem are better installed through rustup components rather than cargo install. For example, rustfmt is commonly managed by rustup, not by Cargo, in modern Rust setups.
Mental Model
Think of cargo install like copying a finished tool into your toolbox.
- The crate is the blueprint
- Cargo builds the tool
- The binary is placed in your toolbox directory
If a newer version exists, Cargo does not always behave like an operating system package manager with a separate update button. Instead, the common approach is closer to:
- build the newer version
- replace the old tool with the new one
So instead of thinking "update this installed package in a managed inventory", think "reinstall this command-line tool with the latest version".
Syntax and Examples
The basic syntax for installing a Cargo binary is:
cargo install crate_name
Example:
cargo install ripgrep
If you want to reinstall or replace an already installed binary, the common command is:
cargo install ripgrep --force
What --force does:
- tells Cargo to overwrite an existing installed package
- is useful when the crate is already installed
- is the common way to refresh a global binary
You can also install a specific version:
cargo install ripgrep --version 14.1.0 --force
This is useful when:
- you want a predictable tool version
- you need to downgrade or pin a version
- a team expects the same CLI version
For Rust tools managed by rustup, the workflow is different. Example:
rustup update
That updates your Rust toolchain and related components, which may include tools such as rustfmt if installed as components.
Step by Step Execution
Consider this command:
cargo install cargo-edit --force
Here is what happens conceptually:
- Cargo looks up the crate named
cargo-edit - It resolves which version to install
- It downloads the crate source if needed
- It compiles the binary
- Because
--forceis present, Cargo replaces the existing installed binary - The new executable is written into your Cargo bin directory
A simple example flow:
cargo install cargo-edit
cargo install cargo-edit --force
Step by step:
- First command installs
cargo-editif it is not already present - Second command rebuilds and reinstalls it even if it already exists
- The old binary is replaced by the newly built one
If you omit --force and the package is already installed, Cargo may refuse to reinstall it, depending on the situation. That is why --force is commonly used when your intent is to update or refresh.
Real World Use Cases
Here are common situations where this matters:
- Updating developer tools: tools like
cargo-edit,cargo-watch, orripgrepmay need newer features or bug fixes - Refreshing CI helper tools locally: your team may use a CLI tool and you need the latest version to match documentation or scripts
- Fixing broken installs: reinstalling with
--forcecan replace a corrupted or outdated binary - Version pinning: you may install a specific version of a tool to match a project or tutorial
- Toolchain maintenance: some tools are managed through
rustup, so knowing whether to usecargo installorrustup updateprevents unnecessary troubleshooting
Example:
cargo install cargo-watch --force
This is a typical way to refresh a tool you use during development.
Real Codebase Usage
In real projects, developers usually do not rely on a separate cargo update command for globally installed binaries. Instead, they use a few practical patterns:
Reinstall with force
The most common pattern:
cargo install some-tool --force
This acts like an update for many CLI tools.
Pin a version for consistency
cargo install wasm-pack --version 0.12.1 --force
This is useful when:
- onboarding developers
- keeping docs accurate
- avoiding unexpected changes from the latest release
Use rustup for official components
For tools tied to the Rust toolchain, developers often prefer:
rustup component add rustfmt
rustup update
This is the standard approach for toolchain components.
Scripted setup
Teams sometimes create setup scripts like:
cargo install cargo-watch --force
cargo install cargo-edit --force
This makes local environment setup repeatable.
Guarding against tool mismatch
In larger codebases, developers may document exact installation commands in README files or bootstrap scripts so everyone uses the same tool version.
Common Mistakes
1. Assuming cargo update updates installed binaries
cargo update is for project dependencies, not globally installed tools.
Broken assumption:
cargo update ripgrep
Why it is wrong:
cargo updateworks inside a Cargo project- it updates dependency resolution in
Cargo.lock - it does not update binaries previously installed with
cargo install
2. Using cargo install without --force and expecting replacement
Example:
cargo install cargo-edit
If cargo-edit is already installed, this may not replace it the way you expect.
Use:
cargo install cargo-edit --force
3. Managing rustfmt with the wrong tool
Many learners install rustfmt with Cargo when the recommended path is often via .

Cheat Sheet
# Install a global Cargo binary
cargo install crate_name
# Reinstall / refresh an installed binary
cargo install crate_name --force
# Install a specific version
cargo install crate_name --version x.y.z --force
# Remove an installed binary
cargo uninstall crate_name
# Update Rust toolchain components
rustup update
Key rules:
cargo installis for global binary crates- there is no separate commonly used built-in
cargo updateworkflow for installed binaries like project dependencies cargo install <crate> --forceis the practical update-style commandcargo updateis for dependencies in a project, not global tools- for tools like
rustfmt, preferrustupwhen they are toolchain components
Quick decision guide:
- Need to update a Cargo-installed CLI? Use
cargo install ... --force - Need to update dependencies in
Cargo.toml? Usecargo update - Need to update Rust itself or
rustfmtcomponent? Userustup update
FAQ
Is there a direct cargo update command for installed binaries?
Not in the same sense as project dependency updates. The common approach is to run cargo install <crate> --force.
How do I update a package installed with cargo install?
Use:
cargo install crate_name --force
This reinstalls the binary and replaces the old version.
What is the difference between cargo update and cargo install --force?
cargo update updates dependency resolution for a project. cargo install --force reinstalls a globally installed CLI tool.
Should I use cargo install for rustfmt?
Usually, rustfmt is better managed through rustup as a component of the Rust toolchain.
Can I install a specific version of a Cargo binary?
Yes:
cargo install crate_name --version x.y.z --force
Mini Project
Description
Create a simple shell setup guide for your Rust development environment that installs or refreshes a few common Cargo-based tools. This helps you practice the difference between installing a tool, reinstalling it with --force, and updating toolchain-managed components separately.
Goal
Build a repeatable setup script that refreshes Cargo-installed CLI tools and updates Rust toolchain components correctly.
Requirements
- Create a script that installs or refreshes at least two Cargo CLI tools using
cargo install - Include
--forcefor tools that should be refreshed - Add a command to update the Rust toolchain with
rustup - Include a comment explaining why
cargo updateis not used here
