python - Google GMail API `installed` 应用程序显示来自模块 SSL.py 的 IOError 13 w/o sudo

Question

我正在尝试使用 GMAIL API 创建一个应用程序来从我的服务器发送自动电子邮件。以简单用户身份运行我的应用程序会产生以下结果:

pankgeorg@snf-25181:~/tomotech/gmailer$ python mailer.py
Traceback (most recent call last):

    self._context.load_verify_locations(ca_certs)
IOError: [Errno 13] Permission denied

另一方面，使用 sudo 运行效果很好

pankgeorg@snf-25181:~/tomotech/gmailer$ sudo python mailer.py
Message Id: 14ad0aea05e*****

老实说，为了使用 --noauth_local_webserver 进行身份验证，我使用 sudo 运行命令，通过身份验证并 chown gmail.storage 再次给自己。 另外，我使用 easy_install 安装，因为 pip install 给我以下错误:

pankgeorg@snf-25181:~/tomotech/gmailer$ sudo pip install --upgrade google_api_python_client

Storing debug log for failure in /root/.pip/pip.logrom oath2client import tool

据我了解，这两种情况的问题根源是相同的。 我还必须注意我的笔记本电脑(我可以在其上正常进行身份验证，在网络浏览器上，而不是 --noauth_local_webserver 上)它工作得很好，即使安装是以相同的方式完成的(pip 的问题也出现在那里)。

提前致谢，抱歉发了这么长的帖子! 我使用的教程: parse arg code for sending mails 应用程序正文几乎是 gmail api 的快速入门。

httplib2 安装程序为其 httplib2/cacerts.txt 文件设置了不正确的权限。一种解决方案是通过运行简单地使其文件对任何人都可读

chmod o+r -R  /usr/local/lib/python2.7/dist-packages/httplib2-0.9-py2.7.egg

但是，最好卸载 pip 安装的版本，并改用操作系统的包管理器，它可能对所有文件都有正确的权限。在 Debian 上，这可以通过

pip uninstall httplib2
apt-get install python-httplib2
