安装ftdi时SWIG没有输出目录

Question

我尝试在OSX上的python中使用ftdi。我以为我安装了所有的东西（包括依赖项和所有的），但是当我试图在我的代码中import ftdi时，它说

File "simple.py", line 11, in <module>
    import ftdi
ImportError: No module named ftdi.

我查看了安装输出，结果发现swig有问题。上面写着：

^{pr2}$

在“under”之后没有任何东西被打印出来。我对这一点完全陌生，我没有在谷歌上找到一个可行的解决方案。有没有人知道可能是什么问题以及如何解决它？完整的日志可以在这篇文章的末尾找到。在

Answer 1

1. 从ftdi1.0开始，导入应该是import ftdi1。如果需要import ftdi，请使用0.20。在
2. 我必须向PYTHONPATH变量添加/usr/lib/python2.7/site-packages/。在
