libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)

Question

My system is macOS 10.13.1 I was try import pycurl is error

ImportError: pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)

I tried these two methods

sudo pip uninstall pycurl
export PYCURL_SSL_LIBRARY=openssl
sudo pip install pycurl

or

sudo pip uninstall pycurl
sudo pip install --compile --install-option="--with-openssl" pycurl

Ive tried multiple variations of this, but none of them seem to work. Any ideas?

I tried other answers to the same questions. But no use. Please help or try to give some ideas how to achieve this — jianyi, Jan 06 '18 at 07:44
If you're looking for general advice on the subject, I will recommend what I do. I try very hard not to install anything directly on osx if I don't have to. Instead I use docker which allows me to describe my runtime environment and dependencies in a reproducible and isolated manner. I'll guarantee you that if you do it right you'll never see errors like this and things will get a lot simpler to install, for your peers and well as you. — erik258, Jan 06 '18 at 17:35
Thank you for your answer but I still want to know how to solve this problem and I haven't used docker and I don't know how to use it with pycharm. — jianyi, Jan 09 '18 at 17:05

On MacOS Catalina (10.5.2) you may have followed all the guidelines and got a similar error:

ImportError: pycurl: libcurl link-time ssl backend (none/other) is different from compile-time ssl backend (openssl)

This is a result of curl missing openssl, which doesn't come with MacOS now. As described in https://blog.birkhoff.me/switching-to-the-openssl-version-of-curl/

To fix:

$ brew upgrade
$ brew uninstall curl
$ brew install curl-openssl
$ echo 'export PATH="/usr/local/opt/curl-openssl/bin:$PATH"' >> ~/.zshrc
