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

谷歌搜索时我什么也没找到，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，但它仍然不会让我安装 3.9.0

编辑：为了让 pyenv 知道 python 的系统版本，我也应该加入这一点，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 并导致相同的错误

EDIT2：似乎我从回溯中丢失了 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，我将尝试在 zlib 上查找更多信息，看看我是否需要安装别的东西

Answer 1

我在尝试在 WSL2/Ubutnu18 上安装带有asdf的 Python 3.8 （它使用与 pyenv 相同的后端）时遇到了类似的问题，并且安装zlib1g-dev不足以解决问题的作者所说的。

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

我希望这对其他人有用！
