except OSError, e: ^ SyntaxError: invalid syntax（baxter SDK編譯過程中出現的問題）

baxter SDK  隻能在python2.7的環境下通過編譯 ---文法格式問題

報錯片段：

Traceback (most recent call last):
  File "/home/yan/baxter_ws/src/baxter_interface/cfg/HeadActionServer.cfg", line 35, in <module>
    from baxter_interface import settings

make: *** [all] Error 2

解決辦法：

使用conda建立新的虛拟環境 使用python2.7版本

conda create -n py27 python=2.7
conda activate py27
           

重新執行

catkin_make
           

如果又發現報錯：

Traceback (most recent call last):
  File "/home/yan/baxter_ws/src/baxter_interface/cfg/HeadActionServer.cfg", line 30, in <module>
    from dynamic_reconfigure.parameter_generator_catkin import (

這次是因為安裝了anaconda

首先嘗試

apt-cache search rospkg
sudo apt-get install python-rospkg
           

上面的方法并沒有效果，借用别人的方法：

conda install setuptools
 pip install -U rosdep rosinstall_generator wstool rosinstall six vcstools
           

成功解決
