我尝试使用Python 3.5的Mac，以及使用virtualenv和Python 3.4的Ubuntu，类似的错误。

我忘了手动安装一些依赖项吗？该软件包是否未使用最新的Python版本进行维护？

感谢。

Answer 1

尝试

sudo apt-get install build-essential
sudo apt-get install python-all-dev
sudo apt-get install libexiv2-dev
sudo apt-get install libboost-python-dev

然后

pip3 install py3exiv2

应该没问题......那些是py3exiv2的构建依赖...

Answer 2

Pawel，问我如何在AWS EC2 Linux2发行版的centOS上构建py3exiv2。我从“ Team Exiv”团队获得了很多帮助，一些会员也在“ openhub.com”上找到了。我已经附上了我开发的原始操作手册。您显然需要选择更新的库。

请记住，这里有粗略的注释，而不是详细且高度修饰的手册。另外，我至少有12个月没有对其进行测试。考虑一下这些步骤在做什么，如果不起作用，请对照库doco检查语法。

这是基于VirtualBox环境构建的，该环境仅与VM设置有关

如果我的回忆是正确的，早期的测试是在Centos 7.4上进行的（？CentOS-7-x86_64-DVD-1708.iso？）。除了在Linux2用户数据和元数据方面，Centos构建与AWS Linux2发行版构建基本相同。

Need to set user-data & meta-data to prep the Linux2 distro. (see AWS doco)
VirtualBox nic to Bridge and active nic
storage to use new seed.iso


update /etc/ssh/sshd_config  
    PermitRootLogin yes
 and 
    PasswordAuthentication yes
    #PasswordAuthentication no

Check disk space needed  !!  need about 4GB 
         Add & mount another vol if needed

~~~~~~~~~~~~~
If using Virtual Box  you can set up folder / directory sharing as follows
 https://www.if-not-true-then-false.com/2010/install-virtualbox-guest-additions-on-fedora-centos-red-hat-rhel/   
For AWS Linux2  (Q1 2018) It found that the CentOS7 process worked perfectly.  (watch the wrong form quote marks)

Answer 3

是的，这是一个挑战。我能够在centOS和AWS EC2 Linux2发行版上“构建”py3exiv2。但是我还没有成功使用MacOS，但是发现使用共享驱动器安装的VirtualBox非常有效。

如果您对运行表有兴趣进行构建，请告诉我，我会将其清理并在此处发布。

无法用pip安装py3exiv2？
