Ubuntu虚拟机中Python SSL模块缺失致Buildozer构建失败求助

环境与错误详情 #

在Ubuntu 22.04.3虚拟机（Python 3.12环境）中运行buildozer android debug时，触发SSL模块不可用错误，具体输出：

running python3 -m venv venv
[INFO]:    Upgrade pip to latest version
[DEBUG]:   -> running bash -c source venv/bin/activate && pip install -U pip
[DEBUG]:        Ignoring "sys._home = value" override
[DEBUG]:        WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
[DEBUG]:        Requirement already satisfied: pip in ./venv/lib/python3.11/site-packages (23.2.1)
[DEBUG]:        WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pip/

已尝试但无效的操作 #

• 执行sudo apt install libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev libtk8.6 libgdm-dev libdb4o-cil-dev libpcap-dev
• 手动编译Python时执行./configure、make、sudo make install
• 手动安装OpenSSL后，编译Python时指定./configure --with-openssl=/home/username/openssl

解决方案 #

1. 重置系统OpenSSL环境 #

卸载手动安装的OpenSSL，改用系统默认兼容版本：

sudo rm -rf /home/username/openssl
sudo apt update && sudo apt install -y libssl-dev openssl --reinstall

2. 重新编译Python3.12并绑定系统SSL #

先清理之前手动编译的Python3.12：

# 若保留编译目录，进入后执行
sudo make uninstall
# 若找不到编译目录，直接删除相关文件
sudo rm -rf /usr/local/bin/python3.12 /usr/local/lib/python3.12

下载Python3.12源码并解压，进入源码目录执行：

./configure --with-openssl=/usr --enable-optimizations
make -j$(nproc)
sudo make altinstall

--with-openssl=/usr指定使用系统SSL，altinstall避免覆盖系统默认Python。

3. 配置Buildozer使用Python3.12 #

编辑项目根目录的buildozer.spec，修改Python版本配置：

python.version = 3.12

验证Python3.12可用性：

python3.12 --version

4. 清理缓存后重新构建 #

删除旧虚拟环境与Buildozer缓存：

rm -rf venv .buildozer

重新执行构建命令：

buildozer android debug
