[英]Error: Unknown argument --licenses flutter doctor --android-licenses
我嘗試用vscode安裝android SDK來編寫flutter。 但是每當啟動 android 模擬器時,它都會要求許可證。 但是每當我使用命令 flutter doctor android 許可證時。 它給了我這個錯誤。 我在用,
ANDROID SDK 平台工具 - 29.0.6
ANDROID SDK 構建工具 - 29.0.3
ANDROID 7 (API:24)
flutter doctor
Doctor summary (to see all details, run flutter doctor -v):

[!] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
✗ Android license status unknown.
Run `flutter doctor --android-licenses` to accept the SDK licenses.

我嘗試了許多 StackOverflow 解決方案,但沒有奏效。 也許過時了。
flutter doctor --android-licenses
Error: Unknown argument --licenses
Usage:
sdkmanager [--uninstall] [<common args>] \
[--package_file <package-file>] [<packages>...]
sdkmanager --update [<common args>]
sdkmanager --list [<common args>]
In its first form, installs, or uninstalls, or updates 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), currently installed packages are
updated to the latest version.
In its third form, all installed and available packages are printed out.
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.
那么如何激活android SDK的許可證呢?
我在運行flutter doctor --android-licenses
時遇到了同樣的問題。 我在沒有使用 Android Studio 的情況下安裝了 android SDK。
以下是我為使其工作而采取的步驟
android-sdk
目錄下latest
內部cmdline-tools
和移動的內容cmdline-tools
吧。 在此之后,我嘗試運行flutter doctor --android-licenses
然后它沒有錯誤地工作並且在我的設備上運行它沒問題。
如果<sdk>/cmdline-tools\\latest
目錄中沒有命令行工具,則會出現此問題。 您可以從這里下載命令行工具,而不是安裝 Android Studio,並將其放在目錄<sdk>/cmdline-tools\\latest
安裝 Android SDK 6.0(Marshmallow)
我通過安裝 android studio 並卸載所有 android 文件並從 android studio 重新安裝來解決它。 然后自動在文件夾中創建許可證。 現在每當我從 vscode 運行模擬器時..它運行順利。
我遇到了這個問題,因為我直接從 android sdk 安裝了所有 android 文件。 我通過 sudo snap android-sdk 安裝了 android sdk。 所以它給我帶來了問題。 要了解更多詳細信息,您可以閱讀本文 - Linux 完整指南上的 Flutter、Android SDK 和 VScode 設置
