Para receber arquivos enviados, primeiro instale o <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Garanta que você criou um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, o ativou e então o instalou, por exemplo:

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

## Everything is Optional

Each component in the new installer is optional. Users can install the component defined in the new installer,
use the equivalent component in `istio-system`, configured with the official installer, or use a different
version or implementation.

For example, you may use your own Prometheus and Grafana installs, or you may use a specialized/custom

@Priority(100)
final class MavenInstaller implements Installer {

    private final DefaultInstaller installer;

    private final ConsumerPomArtifactTransformer consumerPomArtifactTransformer;

    @Inject
    MavenInstaller(DefaultInstaller installer, ConsumerPomArtifactTransformer consumerPomArtifactTransformer) {
        this.installer = requireNonNull(installer);
        this.consumerPomArtifactTransformer = requireNonNull(consumerPomArtifactTransformer);

    /**
     * Install an artifact from a particular file.
     *
     * @param source the file to install
     * @param artifact the artifact definition
     * @param localRepository the local repository to install into
     * @throws ArtifactInstallationException if an error occurred installing the artifact
     */
    void install(File source, Artifact artifact, ArtifactRepository localRepository)

    protected String component() {
        return "installer";
    }

    @Test
    void testArtifactInstallation() throws Exception {
        sessionScope.enter();
        try {
            sessionScope.seed(MavenSession.class, mock(MavenSession.class));

            String artifactBasedir = new File(getBasedir(), "src/test/resources/artifact-install").getAbsolutePath();

Changes to TensorFlow C++ code should conform to
[Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html).

Use `clang-tidy` to check your C/C++ changes. To install `clang-tidy` on ubuntu:16.04, do:

```bash
apt-get install -y clang-tidy
```

You can check a C/C++ file by doing:


```bash
clang-format <my_cc_file> --style=google > /tmp/my_cc_file.cc
diff <my_cc_file> /tmp/my_cc_file.cc

    @Deprecated
    public void install(String basedir, String finalName, Artifact artifact, ArtifactRepository localRepository)
            throws ArtifactInstallationException {
        String extension = artifact.getArtifactHandler().getExtension();
        File source = new File(basedir, finalName + "." + extension);

        install(source, artifact, localRepository);
    }

## Install `PyJWT`

We need to install `PyJWT` to generate and verify the JWT tokens in Python.

Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

	// cmd represents the upgradeCheck command
	cmd := &cobra.Command{
		Use:   "precheck",
		Short: "Check whether Istio can safely be installed or upgraded",
		Long:  `precheck inspects a Kubernetes cluster for Istio install and upgrade requirements.`,
		Example: `  # Verify that Istio can be installed or upgraded
  istioctl x precheck

  # Check only a single namespace
  istioctl x precheck --namespace default

1. Run tests.
- Run `./gradlew :<subproject>:quickTest` where `<subproject>` is the name of the subproject you've changed. 
- For example: `./gradlew :launcher:quickTest`.
2. Install Gradle locally and try out a change in behavior manually. 
- Install: `./gradlew install -Pgradle_installPath=/any/path`
- Use: `/any/path/bin/gradle taskName`.
