Question

我一直无法使用Pyenv在macOS（10.13.6）上安装Python，并且就常见的构建问题用尽了所有建议。

pyenv-doctor报告：未安装OpenSSL开发标头。如各种相关GitHub问题中所述，重新安装OpenSSL无效，没有各种标志设置，例如（以各种组合）：

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"

（在命令行中也尝试了这些。）

（通过Homebrew尝试了OpenSSL 1.02p和1.1）

尝试

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)

没有运气。

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

我怀疑路径或链接丢失/不正确，但是我一直无法确定它可能是什么。任何建议都将受到欢迎。

Answer 1

如果这是与我相同的问题，那是因为您的路径中不应该包含标题。运行brew doctor，您会发现它抱怨。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

应用Kit的答案后；我必须执行以下操作来克服以下事实：我也用自制软件安装了df<-data.frame(Date=c("2018-10-15","2018-10-16","2018-10-17", "2018-10-14","2018-10-15","2018-10-16","2018-10-18","2018-10-19", "2018-10-18","2018-10-21","2018-10-23","2018-10-24","2018-10-27","2018-10-28"),Group=c("a","a","a","b","b","b","b","b","c","c","c","c","c","c"),Gap_Days=c(1,1,1,1,1,2,1,1,3,2,1,3,1,1)) df_expected<-data.frame(Date=c("2018-10-15","2018-10-16","2018-10-17","2018-10-18","2018-10-19","2018-10-27","2018-10-28"),Group=c("a","a","a", "b","b","c","c"),Gap_Days=c(1,1,1,1,1,1,1))：

openssl

那使我工作。还发现此reference对于常见的构建问题很有用。
