Pyenv，Python安装失败：未安装OpenSSL开发header

Question

我一直无法使用 Pyenv 在 macOS (10.13.6) 上安装 Python，并且已经用尽了有关常见构建问题的建议。

pyenv-doctor 报告：OpenSSL development header 未安装。 OpenSSL 的重新安装，如各种相关 GitHub 问题中的建议尚未工作，没有各种标志设置，例如（各种组合）：

export CFLAGS="-I$(brew --prefix openssl)/include"
export CPPFLAGS="-I$(brew --prefix openssl)/include"
export LDFLAGS="-L$(brew --prefix openssl)/lib"
export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig/"
export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"

（也在命令行中尝试了这些。）

（通过 Homebrew 尝试了 OpenSSL 1.02p 和 1.1）

尝试过

brew install readline xz

和

$ CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install 3.6.6

和

$ CFLAGS="-I$(brew --prefix openssl)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-L$(brew --prefix openssl)/lib" pyenv install 3.6.6

和

xcode-select --install
(or via downloadable command line tools installer for reinstallation)

运气不好。

brew link --force openssl

不允许（错误消息说要使用标志）。

也尝试过：

$(brew --prefix)/opt/openssl/bin/openssl

并在此处尝试了 OpenSSL/macOS 建议：

https://solitum.net/openssl-os-x-el-capitan-and-brew/

$PATH 显示：

/usr/local/opt/openssl/bin:/Users/tc/google-cloud-sdk/bin:/Users/tc/Code/git/flutter/bin:/usr/local/sbin:/usr/local/heroku/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Users/tc/google-cloud-sdk/bin:/Users/tc/Code/git/flutter/bin:/usr/local/sbin:/usr/local/heroku/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Users/tc/google-cloud-sdk/bin:/Users/tc/.nvm/versions/node/v8.11.3/bin:/Users/tomclaburn/Code/git/flutter/bin:/usr/local/sbin:/usr/local/heroku/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Applications/Postgres.app/Contents/Versions/latest/bin:/usr/local/mongodb/bin:/usr/local/opt/openssl/bin/openssl:/usr/local/mongodb/bin:/usr/local/mongodb/bin

和.bash_profile包含：

if [ -d "${PYENV_ROOT}" ]; then
   export PATH="${PYENV_ROOT}/bin:${PATH}"
   eval "$(pyenv init -)"
   #eval "$(pyenv virtualenv-init -)"
fi

我怀疑存在 missing/incorrect 路径或 link，但我无法确定它可能是什么。欢迎任何建议。

Answer 1

如果这与我的问题相同，那是因为您的路径中有 headers 不应该存在。运行 brew doctor 你会看到它抱怨。要修复它，您可以这样做：

mkdir /tmp/includes
brew doctor 2>&1 | grep "/usr/local/include" | awk '{=;print}' | xargs -I _ mv _ /tmp/includes

Answer 2

应用 Kit 的答案后；我必须执行以下操作来克服我还使用自制软件安装 openssl 的事实：

CFLAGS="-I$(brew --prefix openssl)/include" \
LDFLAGS="-L$(brew --prefix openssl)/lib" \
pyenv doctor

这让我开始工作。还发现此 reference 对于常见的构建问题很有用。
