但是当我尝试导入pycurl时，我得到了以下错误：

Answer 1

我也有同样的问题，就这样解决了。 首先，我使用Python3和pip3，但同样的方法也适用于pip。在

{我在这里安装了最新的SSL。 您可以用旧的unix方式安装它，也就是下载gzip文件。在

tar -zxvf openssl-1.0.2n.tar.gz

（您的文件可能是其他版本） 然后运行：

^{pr2}$

（这仅适用于64位Mac架构。正常运行/配置） 然后：

make
make test
sudo make install

（使用sudo，因为它可能需要创建文件夹）。 现在您已经安装了OpenSSL。您需要安装PyCurl并告诉它您的OpenSSL头文件。我是这样做的：

pip3 install pycurl  global-option=build_ext  global-option="-L/{OpenSSL-install-directory}/lib"  global-option="-I/{OpenSSL-install-directory}/include"

将{OpenSSL install directory}替换为实际路径。我的是/usr/local/ssl：

pip3 install pycurl  global-option=build_ext  global-option="-L/usr/local/ssl/lib"  global-option="-I/usr/local/ssl/include"

然后安装并工作。在

在拼接时使用了以下资源：

• https://github.com/pyca/cryptography/issues/3489
• Install curl with openssl
• http://pycurl.io/docs/latest/install.html#ssl-certificate-bundle

Answer 2

转载自SSL backend error when using OpenSSL

在阅读了他们的安装文件后，我通过设置一个环境变量并重新安装来解决我的问题

• 删除现有pycurl安装

  pip卸载pycurl

• 导出变量

  export PYCURL_SSL_LIBRARY=openssl

• 安装pycurl

  pip安装pycurl

可能有其他的解决方案，但这对我的virtualenv和pip安装非常适合
