pyinstaller打包shotgun有关的程序

背景

使用pyinstaller打包跟shotgun有关的程序后，在自己电脑上运行都OK，但是编译好的exe在其他人的电脑上运行失败（就是连接Shogun那一步出错），错误内容为：

分析

出错原因：https://github.com/kennethreitz/requests/issues/557

解决方法：http://stackoverflow.com/questions/14486631/pyinstaller-compiled-file-has-ssl-issue-error-185090050

出错的大概原因是：pyinstaller可能没有将httplib2中的cacert.txt文件打包进来，导致编译完成的exe运行时加载失败。

解决方法

在开发过程，不需要修改什么，该怎么弄怎么弄。

在打包之前，需要修改一点shotgun_api3，比如我的是在C:\Python27\Lib\site-packages\shotgun_api3-3.0.14-py2.7.egg\shotgun_api3\lib\httplib2文件夹里，中的__init__.py第180和181行，将

CA_CERTS = os.path.join(os.path.dirname(os.path.abspath(__file__)), "cacerts.txt")

改为

CA_CERTS = os.path.join(os.path.dirname(os.path.abspath(sys.executable)), "cacerts.txt")

然后再执行pyinstaller打包过程，完成之后，将httplib2文件夹里面的cacert.txt拷贝一份到打包好的.exe相同层级即可。

注意：打包完了，记得将init.py改回来啊，别影响了（其他）项目的开发
