Pyenv、Python安装失败：未安装OpenSSL开发头

我一直无法使用Pyenv在macOS（10.13.6）上安装Python，并且已经对常见的构建问题给出了详尽的建议

pyenv doctor报告：未安装OpenSSL开发标头。各种相关GitHub问题中建议的OpenSSL重新安装未起作用，没有各种标志设置，例如（在各种组合中）：

（在命令行put中也尝试了这些。）

（通过自制试用了OpenSSL 1.02p和1.1）

尝试

及

及

及

不走运

brew link --force openssl

是不允许的（错误消息说要使用标志）

还尝试：

$(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_配置文件包含：

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

我怀疑有丢失/不正确的路径或链接，但我无法确定它可能是什么。欢迎提供任何建议

如果这与我的问题相同，那是因为在你的路径中有一些不应该存在的头。运行

brew doctor

，您会看到它在抱怨。要解决此问题，您可以执行以下操作：

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

在应用Kit的答案后；为了克服我还使用自制软件安装了

openssl

，我必须执行以下操作：

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

这让我工作起来了。

还发现这对常见的构建问题很有用。

我很困惑。你想干什么？只需安装python？我正在尝试安装多个版本的python，使用Pyenv来管理它们。Python的单一版本不是问题。我在我的机器上使用了两个版本的Python。我必须使用虚拟环境让它们正常工作。我使用Python3.6和2.7，它们工作良好，配合良好。我使用的是python的Anaconda发行版，所以我不需要pyenv。有许多internet站点可以帮助您在mac上创建虚拟环境。这是一个无痛的任务使用蟒蛇和相当容易的其他方式。一些网站是：；这两个参考资料也解释了为什么最好使用VE的…@4thSpace-你是对的，

pyenv-doctor

选项不再可用。如果您仍然有问题，我的回答中的参考提供了其他选项。我已经将我的操作系统升级到macOS 10.15，不再有这个问题。答案被严重低估。我有这个问题已经一年了。
