升级到 Big Sur 后 Pyenv 崩溃了

如何解决升级到 Big Sur 后 Pyenv 崩溃了

自从升级到 Big Sur 后，Pyenv 就无法工作了。它是这样开始的：

❯ pyenv install 3.8.0
python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools),missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

所以我跑了xcode-select --install。它通过了，但我在 /Library/Developer/CommandLineTools/usr/bin/ 下没有看到 xrun 目录。

我阅读了许多不同的 github 问题页面、StackOverflow 帖子，并尝试了许多不同的东西，包括 brew install zlib sqlite bzip2 libiconv libzip。这就是我现在的位置：

我的 .zshrc 目前看起来是这样的：

if command -v pyenv 1>/dev/null 2>&1; then
  eval "$(pyenv init -)"
fi

export PATH="$HOME/.poetry/bin:$PATH"


export LDFLAGS="-L $(xcrun --show-sdk-path)/usr/lib -L brew --prefix bzip2/lib"
export CFLAGS="-L $(xcrun --show-sdk-path)/usr/include -L brew --prefix bzip2/include"

我也试过 SYSTEM_VERSION_COMPAT=1 pyenv install 3.8.0 但这也没有解决。如果它有帮助，请注意它在 python-build: use zlib from xcode sdk 行异常长时间挂起。

感谢您阅读到这里。任何帮助将不胜感激。

解决方法

这对我有用（有点）。 我遵循了 https://koji-kanao.medium.com/install-python-3-8-0-via-pyenv-on-bigsur-b4246987a548 中的第 1 步和第 2 步 我升级到 BigSur 11.2，从 https://developer.apple.com/xcode/resources/ 安装了 XCode 12.5 beta。我还从 https://developer.apple.com/download/more/?=command%20line%20tools 为 Xcode 12.5 beta 安装了命令行工具（我不知道这是否有必要）

我的 .zshrc 看起来像这样：

eval "$(pyenv init -)"
fi

export PATH="$HOME/.poetry/bin:$PATH"

然后为了安装 python 3.8.0 我跑了： $ CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix bzip2)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix zlib)/lib -L$(brew --prefix bzip2)/lib" pyenv install --patch 3.8.0 < <(curl -sSL https://github.com/python/cpython/commit/8ea6353.patch\?full_index\=1)

这实际上安装了它。但是，当我在现有项目上运行诗歌安装时，它开始安装该软件包，然后突然出现以下错误：

• 安装 pynacl (1.3.0)：失败

  ERROR: Failed building wheel for PyNaCl

这个问题的解决方案是运行 $ /Users/rayhanmuktader/Library/Caches/pypoetry/virtualenvs/desk-backend-kAA1Wc9W-py3.8/bin/python -m pip install pynacl==1.3.0 来安装 pynacl 包。然后再次运行 poetry install 以继续安装过程。冲洗并重复通过 poetry install 安装失败的每个包。
