Question

尝试在Ubuntu 20.04 WSL for Windows 10 上安装带有pyenv 的新Python 版本失败，输出如下：

这些是您日志的相关部分：

[...]

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _curses_panel         _dbm
_gdbm                 _lzma                 _sqlite3
_tkinter              _uuid                 zlib
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
_abc                  atexit                pwd
time

您似乎缺少dependencies that PyEnv requires for building Python。由于您使用的是 Ubuntu，请运行以下命令：

sudo apt update
sudo apt install \
    build-essential \
    curl \
    libbz2-dev \
    libffi-dev \
    liblzma-dev \
    libncursesw5-dev \
    libreadline-dev \
    libsqlite3-dev \
    libssl-dev \
    libxml2-dev \
    libxmlsec1-dev \
    llvm \
    make \
    tk-dev \
    wget \
    xz-utils \
    zlib1g-dev

然后再试一次。
