一 .解决 rosdep init 命令执行不成功 ：
不成功信息：
RROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.
解决方法:
第一步：登陆 IPAddress.com 首页并输入 raw.githubusercontent.com 查询最新网址，一般选择第一个网址就可以，再与 raw.githubusercontent.com 以如下格式输入到/etc/hosts 文件的最后一行.
185.199.108.133 raw.githubusercontent.com
第二步：执行 sudo rosdep init 即可成功.
二 . 解决rosdep update 命令不成功:
不成功信息大体如下:
eading in sources list data from /etc/ros/rosdep/sources.list.d
ERROR: unable to process source [https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml]:
(https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml)
ERROR: unable to process source [https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml]:
(https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml)
ERROR: error loading sources list:
The read operation timed out
解决方法:
第一步: 克隆 rosdistro 文件版本地, 执行:
git clone https://github.com/ros/rosdistro.git
保存到一个明确的位置.
第二步: 将URL路径改为本地 rosdistro 文件路径
1.
cd /文件路径/rosdistro/rosdep/sources.list.d/ sudo vim 20-default.list
修改后:
# os-specific listings first
yaml file:///home/rosSoftware/rosdistro/rosdep/osx-homebrew.yaml osx# generic
yaml file:///home/rosSoftware/rosdistro/rosdep/base.yaml
yaml file:///home/rosSoftware/rosdistro/rosdep/python.yaml
yaml file:///home/rosSoftware/rosdistro/rosdep/ruby.yaml
gbpdistro file:///home/rosSoftware/rosdistro/releases/fuerte.yaml fuerte
2. 需注意: melodic 版本及以前版本在 python2.7 路径下修改, Noetic 在 python3 路径下修改
cd /usr/lib/python3/dist-packages/rosdep2/ sudo vim gbpdistro_support.py
修改后:
FUERTE_GBPDISTRO_URL = 'file:///home/rosSoftware/rosdistro/'
'releases/fuerte.yaml'
3.
cd /usr/lib/python3/dist-packages/rosdep2/ sudo gedit rep3.py
修改后:
REP3_TARGETS_URL = 'file:///home/rosSoftware/rosdistro/releases/targets.yaml'
4.
cd /usr/lib/python3/dist-packages/rosdistro/ sudo gedit __init__.py
修改后:
DEFAULT_INDEX_URL = 'file:///home/rosSoftware/rosdistro/index-v4.yaml'
5.
cd /etc/ros/rosdep/sources.list.d sudo gedit 20-default.list
修改后:
yaml file:///home/rosSoftware/rosdistro/rosdep/osx-homebrew.yaml osx
# generic
yaml file:///home/rosSoftware/rosdistro/rosdep/base.yaml
yaml file:///home/rosSoftware/rosdistro/rosdep/python.yaml
yaml file:///home/rosSoftware/rosdistro/rosdep/ruby.yaml
gbpdistro file:///home/rosSoftware/rosdistro/releases/fuerte.yaml fuerte
第三步: 执行 sudo rosdep update
执行结果若如下则成功:
