使用pip安装加密时出错

Question

Installation fails in Ubuntu 14.04 while I tried to install cryptography . I have tried to check if their are any special requirements from ubuntu side apart from basic python installation, I have also installed the below requirments.

"libxml2-dev",
"libxslt1-dev",
"lib32z1-dev",
"libffi-dev", #Requirement of cffi
"libssl-dev",

Below is the error which it shows.

Answer 1

I found the answer, this error has occurred due because of the low resources on server.

I needed more ram or a bigger swap file for the command to succeed.

Similar Issue: lxml installation error ubuntu 14.04 (internal compiler error)

What I did:

sudo dd if=/dev/zero of=/swapfile bs=1024 count=524288
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

Then pip install cryptography . Worked for me. :)
