在 termux 中安装 pynput 时出现错误

Question

我正在尝试在 Termux 中安装 pynput 以便能够运行我的 python 脚本。 当我尝试 []

pip install pynput

时，我收到此错误消息：

    The 'linux/input.h' and 'linux/input-event-codes.h' include files
    are missing. You will have to install the kernel header files in
    order to continue:

        yum install kernel-headers-$(uname -r)
        apt-get install linux-headers-$(uname -r)
        emerge sys-kernel/linux-headers
        pacman -S kernel-headers

    In case they are installed in a non-standard location, you may use
    the '--evdev-headers' option to specify one or more colon-separated
    paths. For example:

        python setup.py \
          build \
          build_ecodes --evdev-headers path/input.h:path/input-event-codes.h \
          build_ext --include-dirs  path/ \
          install

我不知道下一步该做什么。 请帮忙。

Answer 1

由于 Termux 没有 evdev 所需的 kernel header 文件，您会收到错误。如果没有它，就不可能安装 pynput 和其他需要 evdev 的模块。 关于您关于安装命令的问题，错误消息已包含它：

    yum install kernel-headers-$(uname -r)
    apt-get install linux-headers-$(uname -r)
    emerge sys-kernel/linux-headers
    pacman -S kernel-headers

但不要尝试

我并不是说会发生不好的事情。它就是行不通。 Termux 的存储库中没有内核头文件，据我所知，无风险安装它们的唯一选择是使用 proot。所以你需要这样做：

apt update # Update package repositor(y|ies)
apt upgrade # Upgrade everything just in case
apt install proot # Install **proot**
apt install proot-distro # [OPTIONAL] Install official (made by Termux's developer) proot installer

如果您安装了 proot-distro，则执行以下操作：

proot-distro list # List current available distros

然后

1. 安装你想要的发行版
2. 开始吧
3. 使用该发行版的安装命令再次安装 python（以及您需要的内容），因为 proot 就像虚拟机
4. 安装内核头文件。 根据您的原始发行版选择命令
5. 奔跑

   pip install pynput

Answer 2

我在为不同的包安装 evdev 时遇到相同的错误消息（quantconnect 的“lean”）；安装先决条件解决了这个问题。从 手册页 （我引用 debian 但选择你的发行版）：

可以从以下位置安装最新稳定版本的 python-evdev pypi，前提是你有 gcc/clang、pip 以及 Python 和 Linux 安装在您的系统上的开发标头。安装它们是 分布特定，通常属于以下之一 类别：

   On a Debian compatible OS:

      $ apt-get install python-dev python-pip gcc
      $ apt-get install linux-headers-$(uname -r)

Answer 3

几十年来，Unix 文本和键盘事件处理在curses 和ncurses 中得到了很好的处理，并且可以在Termux 中的python 中运行。只要您缩小 Termux 窗口（捏合缩小），此示例就可以工作，这样在移动光标时就不会遇到边界错误。
