but fail, the message is:
bash: rosbag: command not found

how to install rosbag command?

[siyangy]

You can run this command in docker, see https://github.com/ApolloAuto/apollo/blob/master/README.md.

how to check the ros is running succ?

[startcode]

ROS is a library. If you can run the rosbag play command, your ros library should be OK.

[wanglei828]

Current ros package downloading is integrated into the bazel workspace. If you have never build the apollo repo. Ros package will not exist in you environment.

Hi! I have met the same problem,did you solve it ?

[ycool]

@qwetqwe are you using release docker env or dev docker env?

If using dev docker env, you need run apollo.sh build once to pull ros dependency. logout from docker and docker/scripts/dev_into.sh again. It will setup the ROS env for you.

[qwetqwe]

@ycool I used dev docker env. and I ran apollo.sh build again .but it did not work. Should I setup the apollo-platform first?

[ycool]

@qwetqwe do you logout from docker after apollo.sh build? No need to setup apollo-platform. apollo.sh automatically pulls the dependency.

[qwetqwe]

@ycool I don't know how to logout?
I entered " docker logout" and it displayed
bash: docker: command not found
If I entered in another terminal it displayed
Not logged in to https://index.docker.io/v1/
thank you very much for your reply

[ycool]

type exit and press enter inside docker terminal

[qwetqwe]

＠ycool Ｉ did as you said ,but it still suggested rogbag command not found

[ycool]

Does apollo.sh build work for you? If so, you can check if the ros dependency exists by ls -l /apollo/bazel-apollo/external/ros/setup.bash

[qwetqwe]

build passed. And it showed
lrwxrwxrwx 1 root root 87 Jul 29 15:03 /apollo/bazel-apollo/external/ros/setup.bash -> /root/.cache/bazel/_bazel_root/540135163923dd7d5820f3ee4b306b32/external/ros/setup.bash

[ycool]

It indicates your env has downloaded ros dependency. manually source /apollo/bazel-apollo/external/ros/setup.bash and rosbag should work for you. Generally, dev_into.sh will source ros setup.bash for you.

[qwetqwe]

@ycool After I source it,it worked.
Thank you very much (๑•̀ㅂ•́)و✧

@ycool , i am facing the same question:

root@in_dev_docker:/apollo# rosbag play -l ./docs/demo_guide/demo_2.0.bag
bash: rosbag: command not found

and when i run apollo.sh build, it shows:
Building: no action running
and the code takes ten minutes or so.
while manuallysource /apollo/bazel-apollo/external/ros/setup.bash, it shows:

root@in_dev_docker:/apollo# ls -l /apollo/bazel-apollo/external/ros/setup.bash
ls: cannot access /apollo/bazel-apollo/external/ros/setup.bash: No such file or directory

jwf@jwf-HP:~/apollo$ ls -l /apollo/bazel-apollo/external/ros/setup.bash
ls: 无法访问'/apollo/bazel-apollo/external/ros/setup.bash': 权限不够
jwf@jwf-HP:~/apollo$ sudo ls -l /apollo/bazel-apollo/external/ros/setup.bash
ls: 无法访问'/apollo/bazel-apollo/external/ros/setup.bash': 没有那个文件或目录

did i miss some set-up steps or someting?

[quning18]

@WelfredJiang have you ran into any error when running the dev_into.sh?
