问题描述
我有一个 ROS动力学的 Ubuntu 16.04 OS .
I have an Ubuntu 16.04 OS with ROS kinetic.
当我打开一个终端并输入python时，它将加载python 2.7，而当我尝试import imutils时，它说该目录不存在.
When I open a terminal and type python it loads python 2.7, and as I try to import imutils it says it's not there.
然后，我尝试使用pip install imutils安装它，但是它说:requirment already satisfied in bla/bla/python3.5/bla.
Then, I tried to install it with pip install imutils, but it says: requirment already satisfied in bla/bla/python3.5/bla.
如果我打开终端并输入python3，它将加载 Python 3.5 ，并且当我尝试导入该lib时，它会抱怨找不到c5，并给出一个指向Python ROS软件包所在位置的地址( Python 2.7 ).
If I open the terminal and type python3, it loads Python 3.5, and when I try to import that lib, it complaints that it can't find cv2, and gives an address pointing to where the Python ROS package is located (Python 2.7).
到目前为止，这对我来说很有意义(我知道.bashrc正在加载ROS软件包)，但是，然后，如何在Python版本的ROS中安装imutils?我想将兼容的imutils与我的 ROS Kinetic 一起使用.
Up to this point, it makes sense to me (I am aware of the .bashrc loading the ROS packages), but then, how can I install imutils in the Python version of ROS? I want to use the compatible imutils with my ROS Kinetic.
推荐答案
您的问题是您的pip设置为 Python 3.5 .
Your problem is that your pip is set to Python 3.5.
因此，您可以改用pip2绕过它:
So, you can bypass it using pip2 instead:
pip2 install imutils
或
sudo pip2 install imutils
[注意]:
检查您的pip到Python版本分配的链接:
Check your pip s link to Python versions assignment:
pip --version
pip2 --version
pip3 --version
sudo pip --version
sudo pip2 --version
sudo pip3 --version
然后选择分配给这些pip的所需Python版本，或者您可以更改pip的链接地址().
Then choose the desired Python version which assigned to these pip or you can change the pip s link address (a relevant post).
