Question

最近，我将GAE SDK升级为ver。 1.7.4当我尝试运行开发服务器时，它开始抛出'InvalidCertificateException'。我搜索了这个错误，有些人说它随着时间的推移而消失，但我没有。我应该考虑什么来解决这个问题？我正在使用python框架Django为我的应用程序，如果必须以某种方式。

Answer 1

我找到的快速解决方法：从已安装的SDK中删除文件google_appengine/lib/cacerts/cacerts.txt。

从GoogleAppEngineLauncher开始：

GoogleAppEngineLauncher /内容/资源/ GoogleAppEngineDefault.bundle /内容S /资源/ google_appengine / LIB / cacerts中/ cacerts.txt

编辑＃

从谷歌应用引擎SDK 1.8.1开始，此文件已重命名为 urlfetch_cacerts.txt。仍然在同一目录中并删除它仍然解决了这个问题。

紧凑的答案，截至2014年1月的最新消息（刚刚完成SDK更新）：

rm file /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/cacerts/urlfetch_cacerts.txt

或......

cd /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/cacerts/
rm urlfetch_cacerts.txt

一切都顺利进行。

你最好删除“cacerts.txt”（在同一目录中）。否则，sdk命令行工具也会抛出异常：（

Answer 3

仅供参考：如果您使用的是运行Mavericks的Mac，则此错误可能是由于使用了python 2.7.6或更低版本，其中有一个导致此错误的已知错误。

例如，只需尝试获取任何SSL页面，您就会收到类似的错误：

pip install requests
python

>>> import requests
>>> requests.get("https://github.com")

以上将产生相同的SSL证书错误。在这种情况下，gcloud（Google云SDK）命令都不起作用。

升级到python 2.7.8（或更新的2.7.X）来解决问题（对我有用）。

Answer 4

将Python从2.7.3升级到2.7.9为我修复了它。我使用的是Mac OS X 10.6.8（Snow Leopard）。
