找不到命令 rosinstall ​

如何安装 ​

参考文章Can't find my command "rosinstall"，rosinstall 并未作为 debian 软件包的一部分安装。可以使用 pip 安装，方法如下

shell
pip install -U rosinstall
pip install -U rosinstall

等待片刻，安装完成。

问题重现 ​

执行如下命令

shell
tianbot@ros2go:~/turtlebot_ws/src/turtlebot$ rosinstall . turtlebot.rosinstall
tianbot@ros2go:~/turtlebot_ws/src/turtlebot$ rosinstall . turtlebot.rosinstall

终端显示yaml.load(f) typeerror load() missing 1 required positional argument 'loader',然后进程意外退出。

搜索一番后，参考文章解决报错：TypeError: load() missing 1 required positional argument: ‘Loader‘，找到了解决问题的思路，问题出在PyYAML这个Python模块上。

解决方法 ​

确认 PyYAML 版本 ​

shell
tianbot@ros2go:~$ pip3 list | grep PyYAML
PyYAML                        6.0.1

[notice] A new release of pip is available: 23.3.1 -> 24.0
[notice] To update, run: pip install --upgrade pip
tianbot@ros2go:~$ pip3 list | grep PyYAML
PyYAML                        6.0.1

[notice] A new release of pip is available: 23.3.1 -> 24.0
[notice] To update, run: pip install --upgrade pip

当前版本为6.0.1，需要修改代码调用

修改代码调用 ​

修改报错脚本文件

shell
sudo vi /usr/lib/python3.8/site-packages/wstool/config_yaml.py
sudo vi /usr/lib/python3.8/site-packages/wstool/config_yaml.py

将有问题的代码段，对报错提示的 74 行代码进行修改

python
将 yamldata = yaml.load(stream)
# 替换为下面这行
yamldata = yaml.load(stream, Loader = yaml.FullLoader)
将 yamldata = yaml.load(stream)
# 替换为下面这行
yamldata = yaml.load(stream, Loader = yaml.FullLoader)

再次执行如下命令

shell
tianbot@ros2go:~/turtlebot_ws/src/turtlebot$ rosinstall . turtlebot.rosinstall
tianbot@ros2go:~/turtlebot_ws/src/turtlebot$ rosinstall . turtlebot.rosinstall
shell
