环境：OSX 有人能帮忙解决Web2py错误吗？你知道吗

Answer 1

看起来您运行的是web2py的OSX二进制版本，它有自己的python2解释器（目前，web2py仅在python2下运行），因此它将忽略系统的Python安装（而且web2py不会在python3安装下运行）。web2py二进制版本不附带pymongo，所以我不确定pymongo版本2.2.1来自何处，除非您自己在/web2中安装了它py.app/Contents/Resources/网站-包裹。你知道吗

一种选择是安装python2.7，安装pymongo，然后下载web2py的源代码版本，而不是OSX二进制文件。你知道吗
