python pip cryptography构建轮失败

Question

I am trying to install python packages like quandl. Since I am using pip3 I am installing the package using the following command in ubuntu 16.

sudo pip3 install quandl

This gives me the following error.

Running setup.py clean for cryptography
Failed to build cryptography

I have installed wheel and cryptography as well. But it would not work. Could some one help me with this?

Answer 1

Cleared the error. I installed the Openssl. I upgraded cryptography.

Install Open-ssl using the following command for Ubuntu.

sudo apt-get install libssl-dev
