Question

在我的工作站（Ubuntu Linux）上的virtualenv中安装preppy时，它可以工作，但是当在Amazon Linux的实例上以相同的方式安装它时，我会收到如下错误：

(env)[ec2-user@server t]$ pip install preppy
Downloading/unpacking preppy
  Downloading preppy-2.3.2.tar.gz (42kB): 42kB downloaded
  Running setup.py (path:/home/ec2-user/t/env/build/preppy/setup.py) egg_info for package preppy
    Traceback (most recent call last):

        import preppy
      File "/home/ec2-user/t/env/build/preppy/preppy.py", line 72, in <module>
        isPy3 = sys.version_info.major == 3
    AttributeError: 'tuple' object has no attribute 'major'
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

    import preppy

  File "/home/ec2-user/t/env/build/preppy/preppy.py", line 72, in <module>

    isPy3 = sys.version_info.major == 3

AttributeError: 'tuple' object has no attribute 'major'

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in /home/ec2-user/t/env/build/preppy
Storing debug log for failure in /home/ec2-user/.pip/pip.log

这在检查Python版本是什么时暗示了一个问题，但这次谷歌搜索并没有帮助我。

我知道python包有时依赖于主机软件，例如安装psycopg2我必须先在操作系统上安装Postgres开发包。

那我该如何解决这个错误？

Answer 1

你的ec2实例需要运行（至少）Python 2.7。

直到2.7，

sys.version_info才成为命名元组。
