MacOS上的pyenv zlib错误：

Question

My goal

我正在尝试使用pyenv在我的MBP上并行安装Python 2.7.5和3.6.5。

pyenv Installation

在How can I use Homebrew to install both Python 2 and 3 on Mac?之后，我试过：

$ pyenv install 3.6.5

哪个错误：

python-build: use openssl from homebrew
python-build: use readline from homebrew
Downloading Python-3.6.5.tar.xz...

What have I tried

• 安装zlib：brew install zlib

My question

如何在MBP上使用pyenv安装多个Python环境？

Answer 1

在Mojave上，安装Xcode命令行工具后，必须运行以下命令：

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

Answer 2

brew install zlib
export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
pyenv install 3.7.2

Samsin的回答对我不起作用。我没有Packages目录

Answer 3

pyenv wiki有一个特定于常见构建问题的页面。有一些可能的解决方案提到missing zlib error。

我有相同的ZipImportError，但使用以下命令安装成功：

CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install 3.6.5
