Python 3.x 使用pip安装requirements.txt文件时TLS/SSL出现问题

我正在尝试安装具有以下格式的requirements.txt文件：

build-utils==0.1.1
cffi==1.11.5
fake-rpi==0.6.0
keyboard==0.13.2
numpy==1.14.3
PyAudio==0.2.11
pycparser==2.18
RPi.GPIO==0.6.3
samplerate==0.1.0
websockets==5.0.1

我使用

pip3安装-r./PythonClient/requirements.txt

安装不同的软件包。然而，我一直有SSL的问题

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

这是什么原因造成的？如何修复

编辑：让我澄清一下。我正试图为Mac OS做这件事

我从这篇文章中得出了答案：

如果您在OSX上，并且已从源代码编译python：

使用

brew安装openssl安装openssl

确保按照brew提供的有关设置CPPFALGS>和LDFLAGS的说明进行操作。就我而言，我使用的是openssl@1.1brew formula和我需要以下3>设置，以便python构建过程正确链接到我的SSL库：

export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

假设库安装在该位置

您的python似乎不是用ssl库构建的。也许这篇文章会有帮助：还有，你在使用哪种操作系统？是的，你是对的。可能是@phd的副本，我为之前没有澄清而道歉。我正在寻找一种针对Mac OS的解决方案，因此其他帖子并没有回答我的问题。
