package(
    # copybara:uncomment default_applicable_licenses = ["//tensorflow:license"],
    default_visibility = ["//visibility:private"],
    licenses = ["notice"],

# Filesystem implementation for POSIX environments: Linux, MacOS, Android, etc.

因此，通常会将它们提供为由应用程序读取的环境变量。

## 环境变量

!!! tip
    如果您已经知道什么是"环境变量"以及如何使用它们，请随意跳到下面的下一节。

环境变量（也称为"env var"）是一种存在于 Python 代码之外、存在于操作系统中的变量，可以被您的 Python 代码（或其他程序）读取。

您可以在 shell 中创建和使用环境变量，而无需使用 Python：

=== "Linux、macOS、Windows Bash"

    <div class="termy">

    ```console
    // 您可以创建一个名为 MY_NAME 的环境变量
    $ export MY_NAME="Wade Wilson"

    // 然后您可以与其他程序一起使用它，例如
    $ echo "Hello $MY_NAME"

    Hello Wade Wilson

## macOS

Use the following commands to run a standalone MinIO server on macOS.

pillow==10.3.0
# For image processing by Material for MkDocs
cairosvg==2.7.0
mkdocstrings[python]==0.24.3
griffe-typingdoc==0.2.2
# For griffe, it formats with black
black==24.3.0

    deps = [
        ":immediate_execution_context",
        "//tensorflow/c:conversion_macros",
    ],
)

cc_library(
    name = "tfe_cancellation_manager_internal",
    hdrs = ["tfe_cancellation_manager_internal.h"],
    visibility = [
        "//tensorflow:internal",
    ],
    deps = [
        "//tensorflow/c:conversion_macros",
        "//tensorflow/core:framework",
    ],
)

cc_library(

Sie können Umgebungsvariablen in der Shell erstellen und verwenden, ohne Python zu benötigen:

=== "Linux, macOS, Windows Bash"

    <div class="termy">

    ```console
    // Sie könnten eine Umgebungsvariable MY_NAME erstellen mittels
    $ export MY_NAME="Wade Wilson"

    val javaVersion = JavaVersion.current()
    val isWindows = OperatingSystem.current().isWindows
    val isLinux = OperatingSystem.current().isLinux
    val isMacOsX = OperatingSystem.current().isMacOsX
    val isIntel: Boolean = architecture == "x86_64" || architecture == "x86"
    val isSlowInternetConnection
        get() = System.getProperty("slow.internet.connection", "false")!!.toBoolean()

甚至不需要信用卡。

## 安装 CLI

创建账号后，安装 Deta <abbr title="Command Line Interface application">CLI</abbr>：

=== "Linux, macOS"

    <div class="termy">

    ```console
    $ curl -fsSL https://get.deta.dev/cli.sh | sh
    ```

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console

That will create a directory `./env/` with the Python binaries, and then you will be able to install packages for that local environment.

### Activate the environment

Activate the new environment with:

=== "Linux, macOS"

    <div class="termy">

    ```console
    $ source ./env/bin/activate
    ```

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console

    /**
     * OS family that can be tested for. {@value}
     */
    private static final String FAMILY_OS400 = "os/400";

    /**
     * OpenJDK is reported to call MacOS X "Darwin"
     *
     * @see <a href="https://issues.apache.org/bugzilla/show_bug.cgi?id=44889">bugzilla issue</a>
     * @see <a href="https://issues.apache.org/jira/browse/HADOOP-3318">HADOOP-3318</a>
