Python pkg#u resources.DistributionNotFound:The'；文件'；未找到分发，catkin pkg需要分发

我正在Ubuntu 16.04上安装ros kinetic，当我尝试

catkin\u make

时，出现了这个错误：

您似乎丢失了软件包。试一试

pip3 install docutils

如果您的权限被拒绝，请尝试在它（或sudo）之后添加

--user

。

如果您尝试过

$ sudo pip install docutils

如果出现相同问题，请尝试升级

setuptools

package:

$ sudo pip install -U setuptools

---

命令不起作用，它说“bash:pip3:command not found”，所以我尝试了sudo apt get install docutils，但我得到了这个包docutils是一个虚拟包，由：python3 docutils 0.12+dfsg-1 python docutils 0.12+dfsg-1提供。您应该显式选择一个来安装。E:软件包“docutils”没有安装候选项，因此我尝试了sudo获得安装docutils-*并且得到了这个正在阅读的软件包列表。。。已完成构建依赖关系树以读取状态信息。。。已完成注释，为全局“docutils-”注释选择“docutils writer odt”，为全局“docutils-”注释选择“docutils common”，为全局“docutils-*”docutils common选择“docutils doc”已经是最新版本（0.12+dfsg-1）。docutils公用设置为手动安装。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删除和98未升级您需要安装python3才能获得pip3。尝试

sudo-apt-get-install-python3

。
