# cargo-install(1)
## NAME

cargo-install --- Build and install a Rust binary

## SYNOPSIS

`cargo install` [_options_] _crate_[@_version_]...\
`cargo install` [_options_] `--path` _path_\
`cargo install` [_options_] `--git` _url_ [_crate_...]\
`cargo install` [_options_] `--list`

## DESCRIPTION

This command manages Cargo's local set of installed binary crates. Only
packages which have executable `[[bin]]` or `[[example]]` targets can be
installed, and all executables are installed into the installation root's
`bin` folder. By default only binaries, not examples, are installed.

The installation root is determined, in order of precedence:

- `--root` option
- `CARGO_INSTALL_ROOT` environment variable
- `install.root` Cargo [config value](../reference/config.html)
- `CARGO_HOME` environment variable
- `$HOME/.cargo`

There are multiple sources from which a crate can be installed. The default
source location is crates.io but the `--git`, `--path`, and `--registry` flags
can change this source. If the source contains more than one package (such as
crates.io or a git repository with multiple crates) the _crate_ argument is
required to indicate which crate should be installed.

Crates from crates.io can optionally specify the version they wish to install
via the `--version` flags, and similarly packages from git repositories can
optionally specify the branch, tag, or revision that should be installed. If a
crate has multiple binaries, the `--bin` argument can selectively install only
one of them, and if you'd rather install examples the `--example` argument can
be used as well.

If the package is already installed, Cargo will reinstall it if the installed
version does not appear to be up-to-date. If any of the following values
change, then Cargo will reinstall the package:

- The package version and source.
- The set of binary names installed.
- The chosen features.
- The profile (`--profile`).
- The target (`--target`).

Installing with `--path` will always build and install, unless there are
conflicting binaries from another package. The `--force` flag may be used to
force Cargo to always reinstall the package.

If the source is crates.io or `--git` then by default the crate will be built
in a temporary target directory. To avoid this, the target directory can be
specified by setting the `CARGO_TARGET_DIR` environment variable to a relative
path. In particular, this can be useful for caching build artifacts on
continuous integration systems.

### Dealing with the Lockfile

By default, the `Cargo.lock` file that is included with the package will be
ignored. This means that Cargo will recompute which versions of dependencies
to use, possibly using newer versions that have been released since the
package was published. The `--locked` flag can be used to force Cargo to use
the packaged `Cargo.lock` file if it is available. This may be useful for
ensuring reproducible builds, to use the exact same set of dependencies that
were available when the package was published. It may also be useful if a
newer version of a dependency is published that no longer builds on your
system, or has other problems. The downside to using `--locked` is that you
will not receive any fixes or updates to any dependency. Note that Cargo did
not start publishing `Cargo.lock` files until version 1.37, which means
packages published with prior versions will not have a `Cargo.lock` file
available.

### Configuration Discovery

This command operates on system or user level, not project level.
This means that the local [configuration discovery] is ignored.
Instead, the configuration discovery begins at `$CARGO_HOME/config.toml`. 
If the package is installed with `--path $PATH`, the local configuration 
will be used, beginning discovery at `$PATH/.cargo/config.toml`.

### Feature Selection

The feature flags allow you to control which features are enabled. When no
feature options are given, the `default` feature is activated for every
selected package.

See [the features documentation](../reference/features.html#command-line-feature-options)
for more details.

<dl>

<dt class="option-term" id="option-cargo-install--F"><a class="option-anchor" href="#option-cargo-install--F"></a><code>-F</code> <em>features</em></dt>

<dd class="option-desc">Space or comma separated list of features to activate. Features of workspace
members may be enabled with <code>package-name/feature-name</code> syntax. This flag may
be specified multiple times, which enables all specified features.</dd>

### Compilation Options

<code>&lt;arch&gt;&lt;sub&gt;-&lt;vendor&gt;-&lt;sys&gt;-&lt;abi&gt;</code>.</p>
<p>Possible values:</p>
<ul>
<li>Any supported target in <code>rustc --print target-list</code>.</li>
<li><code>"host-tuple"</code>, which will internally be substituted by the host’s target. This can be particularly useful if you’re cross-compiling some crates, and don’t want to specify your host’s machine as a target (for instance, an <code>xtask</code> in a shared project that may be worked on by many hosts).</li>
<li>A path to a custom target specification. See <a href="../../rustc/targets/custom.html#custom-target-lookup-path">Custom Target Lookup Path</a> for more information.</li>
</ul>
<p>This may also be specified with the <code>build.target</code> <a href="../reference/config.html">config value</a>.</p>
<p>Note that specifying this flag makes Cargo run in a different mode where the
target artifacts are placed in a separate directory. See the
<a href="../reference/build-cache.html">build cache</a> documentation for more details.</dd>

specified with the <code>CARGO_TARGET_DIR</code> environment variable, or the
<code>build.target-dir</code> <a href="../reference/config.html">config value</a>.
Defaults to a new temporary folder located in the
temporary directory of the platform.</p>
<p>When using <code>--path</code>, by default it will use <code>target</code> directory in the workspace
of the local crate unless <code>--target-dir</code>
is specified.</dd>


<dt class="option-term" id="option-cargo-install---debug"><a class="option-anchor" href="#option-cargo-install---debug"></a><code>--debug</code></dt>

<dd class="option-desc">Output information how long each compilation takes, and track concurrency
information over time. Accepts an optional comma-separated list of output
formats; <code>--timings</code> without an argument will default to <code>--timings=html</code>.
Specifying an output format (rather than the default) is unstable and requires
<code>-Zunstable-options</code>. Valid output formats:</p>
<ul>
<li><code>html</code> (unstable, requires <code>-Zunstable-options</code>): Write a human-readable file <code>cargo-timing.html</code> to the
<code>target/cargo-timings</code> directory with a report of the compilation. Also write
a report to the same directory with a timestamp in the filename if you want
to look at older runs. HTML output is suitable for human consumption only,
and does not provide machine-readable timing data.</li>
<li><code>json</code> (unstable, requires <code>-Zunstable-options</code>): Emit machine-readable JSON
information about timing information.</li>

existing <code>Cargo.lock</code> file was originally generated. Cargo will exit with an
error when either of the following scenarios arises:</p>
<ul>
<li>The lock file is missing.</li>
<li>Cargo attempted to change the lock file due to a different dependency resolution.</li>
</ul>
<p>It may be used in environments where deterministic builds are desired,

flag, Cargo will stop with an error if it needs to access the network and
the network is not available. With this flag, Cargo will attempt to
proceed without the network if possible.</p>
<p>Beware that this may result in different dependency resolution than online
mode. Cargo will restrict itself to crates that are downloaded locally, even
if there might be a newer version as indicated in the local copy of the index.
See the <a href="cargo-fetch.html">cargo-fetch(1)</a> command to download dependencies before going
offline.</p>
