Question

在Ubuntu上使用dev_appserver.py在本地运行应用程序时出现此错误它是由于python版本，因为它在python运行时文件中显示错误？
早些时候，同样的版本在Windows 8下工作。

Answer 1

在错误输出中，它说：

TypeError：％d format：需要一个数字，而不是NoneType

这可能意味着，您需要提供一个数字，而不是未分配的变量。

Answer 2

我遇到了同样的问题。通过在文件夹_python_runtime.py

中的appengineSDK中创建~/bin/的符号链接来解决此问题。

像：

ln -s /wherever/sdks/google_appengine/_python_runtime.py /home/username/bin/

谷歌应用引擎dev_appserver.py错误
