flutter 医生 - 如何解决 Android sdkmanager cmdline-tools 组件丢失？

Question

我正在尝试在 macOS Monterey 12.1 上安装/设置flutter_macos_2.10.2-stable 。

Java 版本：

echo $JAVA_HOME

Output：

/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home

在 Android Studio 中安装了Android Studio Bumblebee 2021.1.1 Patch 1 （同时安装了flutter-dev 64.1.2插件）。

---

在~/.bash_profile里面：

export ANDROID_HOME="/Users/pnwlover/Library/Android/sdk";

export FLUTTER_HOME="/Users/pnwlover/DevTools/flutter/flutter_macos_2.10.2-stable";

PATH="/usr/local/bin:$PATH:/usr/local/sbin:$FLUTTER_HOME/bin:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools/bin:$ANDROID_HOME/tools/bin";

现在，当我运行flutter doctor -v时：

flutter doctor -v

尝试这样做时：

sdkmanager --install "cmdline-tools;latest"

收到以下警告：

Warning: Unknown argument --install
Usage: 
  sdkmanager [--uninstall] [<common args>] [--package_file <file>] [<packages>...]
  sdkmanager --update [<common args>]
  sdkmanager --list [<common args>]
  sdkmanager --licenses [<common args>]

In its first form, installs, or uninstalls, or updates packages.
    By default, the listed packages are installed or (if already installed)
    updated to the latest version.

    --uninstall: uninstalled listed packages.

    <package> is a sdk-style path (e.g. "build-tools;23.0.0" or
             "platforms;android-23").
    <package-file> is a text file where each line is a sdk-style path
                   of a package to install or uninstall.
    Multiple --package_file arguments may be specified in combination
    with explicit paths.

In its second form (with --update), all installed packages are
    updated to the latest version.

In its third form, all installed and available packages are printed
    out.

In its fourth form (with --licenses), show and offer the option to
     accept licenses for all available packages that have not already been
     accepted.

Common Arguments:
    --sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK 
                              containing this tool

    --channel=<channelId>: Include packages in channels up to <channelId>.
                           Common channels are:
                           0 (Stable), 1 (Beta), 2 (Dev), and 3 (Canary).

    --include_obsolete: With --list, show obsolete packages in the
                        package listing. With --update, update obsolete
                        packages as well as non-obsolete.

    --no_https: Force all connections to use http rather than https.

    --proxy=<http | socks>: Connect via a proxy of the given type.

    --proxy_host=<IP or DNS address>: IP or DNS address of the proxy to use.

    --proxy_port=<port #>: Proxy port to connect to.

* If the env var REPO_OS_OVERRIDE is set to "windows",
  "macosx", or "linux", packages will be downloaded for that OS.
