在MacOSBigSur上使用pyenv安装python3.6时出现问题

html5 • • 问答

在我的 MacBook Air OS Big Sur 上安装 Python 3.6.13 时，使用命令 pyenv install 3.6.13 我收到此错误：

Installing Python-3.6.13...
python-build: use readline from homebrew
python-build: use zlib from xcode sdk

任何有关如何解决此问题或其他解决方法以安装 python 3.6.13 的建议将不胜感激。我目前有 python 3.8，但需要 3.6 才能运行：

conda install -c deezer-research spleeter

感谢 jordanm，解决方案是遵循https://github.com/pyenv/pyenv/issues/1740#issuecomment-738749988

brew reinstall zlib bzip2

从人们的评论来看（感谢 Lukasz Czerwinski 和 Alex Veksler），似乎很多人认为下一步是可选的（甚至是危险的）并且宁愿跳过它；不过，如果没有其他工作，值得一试：

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

无论您是否选择跳过最后一步，请继续编辑.zshrc或.bashrc使用：

nano ~/.zshrc or nano ~/.bashrc

并添加：

export PATH="$HOME/.pyenv/bin:$PATH"
export PATH="/usr/local/bin:$PATH"

eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
export LDFLAGS="-L/usr/local/opt/zlib/lib -L/usr/local/opt/bzip2/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include -I/usr/local/opt/bzip2/include"

编辑并保存该文件后，运行：

. ~/.zshrc or . ~/.bashrc

然后运行下面的命令进行安装（将3.6.0更改为所需的补丁）

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 3.6.0 < <(curl -sSL https://github.com/python/cpython/commit/8ea6353.patch?full_index=1)

  • I confirm it worked for Python 3.6.13 for pyenv 1.2.26 on MacOS Big Sur (11.2.3). (Actually, I skipped `sudo rm -rf /Library/Developer/CommandLineTools` and `xcode-select --install` but followed all the rest)
  • It worked for python 3.6.0 MacOs 11.4

根据这个：https : //github.com/pyenv/pyenv/issues/1737#issuecomment-731672292这与提交问题有关，以下修复了它。它对我有用。

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 3.6.13 < <(curl -sSL https://github.com/python/cpython/commit/8ea6353.patch?full_index=1)

以上是在MacOSBigSur上使用pyenv安装python3.6时出现问题的全部内容。
