系统ubuntu20.04
ros noetic + humble(源码安装失败,放弃源码安装了)
ubuntuvcs_2">1. ubuntu安装vcs
拉取autoware源码的时候需要用到命令
vcs import src < autoware.ai.repos
但是ubuntu默认没有安装vcs工具(zsh: command not found: vcs)
应使用以下命令安装:
sudo apt-get install python3-vcstool
不是apt-get install vcs(笑)

2. ros2:未找到命令
或者:
E: 无法定位软件包 ros-humble-desktop
ros2命令用不了,用source命令运行bash文件还是不行,讲道理source了之后在当前终端下是可以运行ros2命令的,在其他没有source的终端才会出现“ros2:未找到命令”的情况。为什么source了也不行呢??
ps. rosversion -d
是可以查看ros安装版本的,输出了noetic,如下:
在不同ROS版本采用的Python里看到了这句:
1、noetic是ROS1的终极版本,建议后续使用ROS2版本,需要注意:noetic之前的版本默认使用的是Python2,noetic之后的ROS则使用Python3
啊?!所以noetic是ros1的版本啊,怪不得用不了ros2的命令呢 -_-||
目前humble是ros的长期支持版本(LTS)版,打算安装humble了,不知道noetic和humble两个版本共存会不会出问题
安装教程参照【古月居】古月·ROS2入门21讲
↑↑↑
× 错!古月居的这个教程是从ubuntu22.04版本安装的humble,安装过程较为简单,但是对于我现在用的ubuntu20.04系统,humble仅支持源码编译,这种安装过程参照大佬的教程:ros2humble源码编译 ubuntu系统。
前面都没有问题,直到第六步、在工作空间中编译源码的colcon build --symlink-install
这一步,必须要用***,所以我又装了一个***的linux版本,安装过程参照另一大佬教程linux ***最速安装使用,注意装完***、重启后再次运行colcon build --symlink-install
才有效!!
ubuntu2004ros2_humble_39">2.0 放弃ubuntu20.04+ros2 humble源码安装了!!
源码编译一共有346个包,我装到大概第140多个就实在是装不了了,报错例子如下。这样一个包一个包的装下去也不是办法,所以我决定,在一个干净的环境里开始我的ros之路:重装系统ubuntu22.04 + ros2(humble版本),参见 ubuntu+ros新手笔记(二)。
