failed安装pythonsetup_无法使用PIP和setup.py安装Python加密软件包

When I try to install the Cryptography package for Python through either pip install cryptography or by downloading the package from their site and running python setup.py, I get the following error:

I found other egg_info error posts (here and here) but the solutions there provided wouldn't solve my problem. Also, I am able to install other packages through PIP.

PIP version 1.5.4 setuptools version 2.2

解决方案

I had a similar issue, and found i was simply missing a dependancy (libssl-dev, for me). As referenced in https://cryptography.io/en/latest/installation/, ensure that all dependancies are met:

On Windows

If you’re on Windows you’ll need to make sure you have OpenSSL installed. There are pre-compiled binaries available. If your installation is in an unusual location set the LIB and INCLUDE environment variables to include the

corresponding locations. For example:

C:> pathtovcvarsall.bat x86_amd64

C:> set LIB=C:OpenSSL-1.0.1f-64bitlib;%LIB%

C:> set INCLUDE=C:OpenSSL-1.0.1f-64bitinclude;%INCLUDE%

C:> pip install cryptography

Building cryptography on Linux

cryptography should build very easily on Linux provided you have a C compiler, headers for Python (if you’re

not using pypy), and headers for the OpenSSL and libffi libraries available on your system.

For Debian and Ubuntu, the following command will ensure that the required dependencies are installed:

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

For Fedora and RHEL-derivatives, the following command will ensure that the required dependencies are installed:

sudo yum install gcc libffi-devel python-devel openssl-devel

You should now be able to build and install cryptography with the usual.

pip install cryptography
