Question

我是Google App Engine的新手，所以请耐心等待。

在尝试在本地设置GAE的hello-world Python项目时，我收到一些关于GAE如何不支持python 2.7的错误。

如何在本地配置GAE以使其指向我的自定义python 2.5安装，它位于/usr/local/python-2.5而不是默认系统？（2.7与狮子）

我的系统配置：

OS: Mac OS 10.7
GoogleAppEngineLauncher: 1.5.2

我尝试运行应用时在控制台中看到的错误：

Answer 1

我发现使用GAE SDK和python 2.7的最简单方法是安装Mac端口（http://www.macports.org/）并从那里安装python 2.7。

安装macport后：

$ sudo port install python27  # To install python 2.7

然后从Googleappenginelauncher菜单中打开Preferences并将/opt/local/bin/python2.7放在Python路径字段中。

例如，要安装PIL或lxml，只需在shell中输入以下命令：

# For PIL
$ sudo port install py27-pil

# For Lxml
$ sudo port install py27-lxml

Answer 2

在启动器中，单击GoogleAppEngineLauncher -> Preferences，并在标记为“Python Path”的字段中填写Python二进制文件的路径。

使用Lion为GAE配置python
