收到sdk参数，但此参数已弃用

Question

我正在使用Buildozer从我的python/kivy文件制作一个应用程序。运行此命令行后：

buildozer android debug deploy run

我有一个错误：

WARNING: Received a --sdk argument, but this argument is deprecated and does nothing.
No compiled python is present to zip, skipping.
No setup.py/pyproject.toml used, copying full private data into .apk.
Error while running "/home/kouhi/kouhi-company/idea4/1/.buildozer/android/platform/build-armeabi-v7a/build/other_builds/hostpython3/desktop/hostpython3/native-build/python3 -OO -m compileall -b -f /home/kouhi/kouhi-company/idea4/1/.buildozer/android/app"
This probably means one of your Python files has a syntax error, see logs above
# Command failed: /usr/bin/python3 -m pythonforandroid.toolchain apk --debug --bootstrap=sdl2 --dist_name myapp --name 'My Application' --version 0.1 --package org.test.myapp --minsdk 21 --ndk-api 21 --private /home/kouhi/kouhi-company/idea4/1/.buildozer/android/app --android-entrypoint org.kivy.android.PythonActivity --android-apptheme @android:style/Theme.NoTitleBar --orientation portrait --window --copy-libs --arch armeabi-v7a --color=always --storage-dir="/home/kouhi/kouhi-company/idea4/1/.buildozer/android/platform/build-armeabi-v7a" --ndk-api=21

我正在使用ubuntu。如果你需要更多的信息，请告诉我

我在终端中发现的语法错误是：

***   File "/home/kouhi/kouhi-company/idea4/1/.buildozer/android/app/buildozer/android_ndk/android-ndk-r20b/prebuilt/linux-x86_64/bin/smtpd.py", line 123

                  ^

基于这些，我想主要的问题是我的linux上有两个版本的python（python2和python3）。对于kivy，我必须使用python3。当我在buildozer中有python2.7文件夹时，我认为buildozer不理解它。
我应该怎么做才能让buildozer只使用python3而不使用python2
