【问题描述】:
当我想使用串行库时,我得到这个错误:
$ ./console.py Traceback(最近一次调用最后一次):文件 “./console.py”,第 7 行,在 导入串行 ImportError:没有名为串行的模块
我在 Windows7 中有 Cygwin
$ uname -a CYGWIN_NT-6.1 ES-T20019350 1.7.24(0.269/5/3) 2013-08-15 11:59 x86_64 Cygwin
而我的 Python 版本是 3:
Python 3.2.5(默认,2013 年 7 月 30 日,20:11:30)
谁能告诉我怎样才能让连续剧正常工作?我将需要它来向我的串行端口运行串行流量:

if ser.isOpen():

#and discard all that is in buffer
#write data
ser.write("ac_spi_slash 3\x0D")

【问题讨论】:
-
您尝试安装了吗?
-
如何在 Cygwin 中安装它? Cygwin 没有 apt-get install 命令!
-
这是 pySerial 吗?有多种安装方式 - pyserial.sourceforge.net/pyserial.html#installation
