没有名为urdf2webots - pip的模块在sys.path之外安装了包

Question

我通过pip install urdf2webots安装了一个软件包。在使用命令python -m urdf2webots.importer --input=Rover_2022.urdf --output=Rover_2022.proto时，我得到了/bin/python: No module named urdf2webots。我该怎么解决这个问题？

无sudo

• which python返回/bin/python
• pip show urdf2webots返回

Name: urdf2webots
Version: 1.0.16

• 如果我让python打印sys.path，我得到：

$ python

>>> import sys
>>> sys.path
['', '/opt/ros/foxy/lib/python3.8/site-packages', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']
>>>

用sudo

值得注意的是，我还用sudo尝试了所有这些命令，看看它是否改变了安装包的位置。的确如此，但问题依然存在：

• $ sudo python -m urdf2webots.importer --input=Rover_2022.urdf --output=Rover_2022.proto收益率/usr/bin/python: No module named urdf2webots
• sudo which python收益率/usr/bin/python
• sudo pip show urdf2webots给

我认识到，在这两种情况下，urdf2webots的位置都与sys.path的任何路径不匹配，但我不知道如何解决这个问题。有小费吗？

Answer 1

你可以试试：

python -m pip install urdf2webots

这将为您想要使用的默认python安装库。
