Question

我正准备在寡妇10的ubuntu bash上使用buildozer和kivy构建Android应用但我遇到这样的错误

 ERROR: Could not find a version that satisfies the requirement Cython (from versions: none)
ERROR: No matching distribution found for Cython

我不知道问题出在哪里，我该如何解决，请帮忙

Answer 1

在我的Ubuntu VM上有同样的问题。安装libssl-dev为我解决了这个问题。

sudo apt-get update
sudo apt-get install libssl-dev

Answer 2

在 CentOS 7 上有同样的问题。安装 ssl devel 包解决了这个问题。按照以下命令

sudo yum install openssl-devel buildozer android 清洁 buildozer android 调试部署运行

Answer 3

当您在安装 buildozer 依赖项期间不包含 libssl-dev 时会发生这种情况。

This link 告诉 buildozer 所需的依赖项。因此，安装所有必需的依赖项的过程是：

sudo apt update
sudo apt install -y git zip unzip openjdk-8-jdk python3-pip autoconf libtool pkg-config zlib1g-dev libncurses5-dev libncursesw5-dev libtinfo5 cmake libffi-dev libssl-dev
pip3 install --user --upgrade Cython==0.29.19 virtualenv  # the --user should be removed if you do this in a venv

# add the following line at the end of your ~/.bashrc file
export PATH=$PATH:~/.local/bin/

需要注意的重要事项

如果你没有安装这个 (libssl-dev) buildozer 依赖，最初并且已经执行了

buildozer android debug deploy run

只需使用

添加此依赖项

sudo apt-get install libssl-dev

并运行 buildozer android debug deploy run 将再次抛出相同的错误。所以改为执行这个

sudo apt-get install libssl-dev
buildozer android clean

现在你应该可以走了。

错误：找不到适用于Cython的匹配分布
