yum install python27-devel resolves compiling error.

New issue, running: ./letsencrypt-auto --debug --manualresults in:

Updating letsencrypt and virtual environment dependencies......
Requesting root privileges to run with virtualenv: /root/.local/share/letsencrypt/bin/letsencrypt --debug --manual
Traceback (most recent call last):

pip install pyopenssl does not resolve this.

[arleslie]

Just realized there is another issue that already reports this: #1680

[MatthewDaniels]

I got the same ImportError, and used sudo yum install opensll.

I also was able to use python27-virtualenv (as opposed to python27-devel).

+1 @arleslie

$ sudo yum install python27-devel

It help resolve my issue, but before I ran that. I've ran the following commands.

$ sudo yum -y install gcc gcc-c++ kernel-devel
$ sudo yum -y install python-devel libxslt-devel libffi-devel openssl-devel
$ pip install cryptography

I'm not sure if you need the 2nd batch of commands.

We don't officially support for Amazon Linux yet, but if you're using Amazon Linux 2 you can use the Centos/RHEL 7 instructions on our site.

Closing in favor of tracking support at #6505.
