在 wsl2 ubuntu 20.04 上尝试 (pyenv install -v 3.9.0) 时 pyenv 构建失败

Question

已解决：解决方案是我需要 zlib1g-dev

这是 pyenv 产生的错误

我在谷歌搜索时没有发现任何相关内容，也不知道发生了什么。我所做的步骤是，首先安装 pyenv 安装程序并运行该脚本，然后尝试运行 (pyenv install -v 3.9.0)

系统确实安装了 python3.8 并且 pyenv 似乎知道它，但它仍然不允许我安装 3.9.0

编辑：我还应该添加它，以便让 pyenv 了解 python 的系统版本，我这样做了（sudo ln -s /usr/bin/python3 /usr/bin/python）。另一件事是我还尝试使用名为 asdf 的工具安装 3.9.0，这导致了相同的错误

编辑2：看起来我在回溯中缺少zlib，但我在ubuntu上并且确实安装了zlib1g，从我查找的内容来看，这就是zlib在ubuntu 20.04上的内容，我将尝试找到有关zlib的更多信息，看看我是否需要安装其他东西

我在尝试在 WSL2/Ubutnu18 上安装 Python 3.8 asdf（使用与 相同的后端）时遇到了类似的问题，并且安装不足以解决问题，正如问题作者所述。pyenvzlib1g-dev

因此，作为一个更通用的解决方案，我发现安装pyenvUbuntu 推荐的所有依赖项确实解决了问题（我也asdf怀疑）。pyenv不同操作系统的依赖项可以在这里找到：https ://github.com/pyenv/pyenv/wiki#suggested-build-environment

我希望这对其他人有用！
