ImportError: pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)

solution:

pip3 uninstall pycurl

export PYCURL_SSL_LIBRARY=nss

pip3 install --ignore-installed pycurl

備注：如果uninstall無法移除，則手動移除

mv /usr/local/python3/lib/python3.6/site-packages/pycurl* /home

SSL庫可以通過curl -V檢視

$curl -V
