我在 Ubuntu 16.04 上安装 ros kinetic，当我尝试 catkin_make 时出现此错误：

【解决方案1】：

您似乎缺少docutils 包。试试

pip3 install docutils

如果您的权限被拒绝，请尝试在其后添加 --user（或 sudo）。

【讨论】：

命令不起作用它说“bash：pip3：找不到命令”所以我尝试了 sudo apt-get install docutils 但我得到了这个包 docutils 是由提供的虚拟包：python3-docutils 0.12 +dfsg-1 python-docutils 0.12+dfsg-1 你应该明确选择一个来安装。 E: 包 'docutils' 没有安装候选
然后我尝试了 sudo apt-get install docutils-* 并得到了这个 Reading package lists... Done Building dependency tree Reading state information... Done Note, selection 'docutils-writer-odt'对于 glob 'docutils-' 注意，为 glob 'docutils-' 选择 'docutils-common' 注意，对于 glob 'docutils-*' 选择 'docutils-doc' docutils-common 已经是最新版本(0.12+dfsg-1)。 docutils-common 设置为手动安装。 docutils-doc 已经是最新版本（0.12+dfsg-1）。 docutils-doc 设置为手动安装 0 升级，0 新安装，0 删除，98 未升级
您需要安装python3才能获得pip3。试试sudo apt-get install python3。

【解决方案2】：

如果你尝试过

$ sudo pip install docutils

遇到同样的问题，然后尝试升级setuptools 包：

$ sudo pip install -U setuptools
