Question

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 install -r ./PythonClient/requirements.txt安装不同的软件包。但是，我一直遇到SSL问题。

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting build-utils==0.1.1 (from -r ./PythonClient/requirements.txt (line 1))

是什么原因造成的，我该如何解决？

编辑：让我澄清一下。我正在尝试针对Mac OS执行此操作。

从这篇文章中，我得出了答案："SSL module in Python is not available" when installing package with pip3

如果您在OSX上并且已经从源代码编译了python：

使用brew install openssl
安装openssl
确保遵循brew提供的有关设置CPPFLAGS和LDFLAGS的说明。就我而言，我使用的是openssl@1.1 brew公式，并且需要以下3个设置来正确建立python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"
假定该库已安装在该位置。
