# Required ENV vars:

#
# Optional ENV vars
# -----------------
#   M2_HOME - location of maven2's installed home dir
#   MAVEN_OPTS - parameters passed to the Java VM when running Maven

However, if you use the `pip install fastapi` command, the `python-multipart` package is not included by default.

To install it manually, make sure you create a [virtual environment](../../virtual-environments.md), activate it, and then install it with:

```console
$ pip install python-multipart
```

Quick Build
-------
If you want to bootstrap Maven, you'll need:
- Java 17+
- Maven 3.9.0 or later
- Run Maven, specifying a location into which the completed Maven distro should be installed:
    ```
    mvn -DdistributionTargetDir="$HOME/app/maven/apache-maven-4.1.x-SNAPSHOT" clean package
    ```


[home]: https://maven.apache.org/
[license]: https://www.apache.org/licenses/LICENSE-2.0

```
fastapi[standard]>=0.113.0,<0.114.0
pydantic>=2.7.0,<3.0.0
```

通常你会用 `pip` 安装这些依赖，例如：

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic
```

</div>
