2022解决ROS rosdep init/update，成功率百分百亲测可用

这个解决方法是我在群里看到的，近期装了很多次ros都能完美解决，特地转载出来分享给大家，也给自己mark一下。

在安装ROS的过程中，很多同学在执行上述指令时会提示以下错误：

ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.

通常的解决办法是用手机热点

或者查询 

https://raw.githubusercontent.com的实际IP地址，但是也有可能会失效。

偶然的机会看到一教程的解决方案。

博主的思路是新思路:将相关资源备份到 gitee,修改 rosdep 源码,重新定位资源。成功率是百分百。

整理修改后提供解决ROS rosdep init/update报错的方法（终极版）。

步骤1

进入到 sources.list.d 文件夹（如果没有，则用mkdir指令新建）

修改 gedit 20-default.list

cd /etc/ros/rosdep/sources.list.d
sudo gedit 20-default.list

将里面所有的 

raw.githubusercontent.com/ros/rosdistro/master
替换成

gitee.com/wybros/rosdistro/raw/master 

修改前：

# os-specific listings first
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx

# generic
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/ruby.yaml
gbpdistro https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml fuerte

# newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro index.yaml instead

修改后：

# os-specific listings first rosdep update
yaml https://gitee.com/wybros/rosdistro/raw/master/rosdep/osx-homebrew.yaml osx

# generic
yaml https://gitee.com/wybros/rosdistro/raw/master/rosdep/base.yaml
yaml https://gitee.com/wybros/rosdistro/raw/master/rosdep/python.yaml
yaml https://gitee.com/wybros/rosdistro/raw/master/rosdep/ruby.yaml
gbpdistro https://gitee.com/wybros/rosdistro/raw/master/releases/fuerte.yaml fuerte

# newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro index.yaml instead

步骤2

进入到 rosdep2 文件夹，

修改 gbpdistro_support.py

cd /usr/lib/python2.7/dist-packages/rosdep2/
sudo gedit gbpdistro_support.py

将里面所有的 

raw.githubusercontent.com/ros/rosdistro/master
替换成

gitee.com/wybros/rosdistro/raw/master 

修改后如下

FUERTE_GBPDISTRO_URL = 'https://gitee.com/wybros/rosdistro/raw/' \
    'master/releases/fuerte.yaml'

步骤3

进入到 rosdep2 文件夹，

修改 rep3.py

cd /usr/lib/python2.7/dist-packages/rosdep2/
sudo gedit rep3.py

将里面所有的 

raw.githubusercontent.com/ros/rosdistro/master
替换成

gitee.com/wybros/rosdistro/raw/master 

修改后如下

REP3_TARGETS_URL = 'https://gitee.com/wybros/rosdistro/raw/master/releases/targets.yaml'

步骤4

进入到 rosdep2 文件夹，

修改 sources_list.py

cd /usr/lib/python2.7/dist-packages/rosdep2/
sudo gedit sources_list.py

将里面所有的 

raw.githubusercontent.com/ros/rosdistro/master
替换成

gitee.com/wybros/rosdistro/raw/master 

修改后如下

DEFAULT_SOURCES_LIST_URL = 'https://gitee.com/wybros/rosdistro/raw/master/rosdep/sources.list.d/20-default.list'

步骤5

进入到 rosdistro 文件夹

修改 __init__.py

cd /usr/lib/python2.7/dist-packages/rosdistro/
sudo gedit __init__.py

将里面所有的 

raw.githubusercontent.com/ros/rosdistro/master
替换成

gitee.com/wybros/rosdistro/raw/master 

修改后如下

DEFAULT_INDEX_URL = 'https://gitee.com/wybros/rosdistro/raw/master/index-v4.yaml'

最后

打开新终端执行

rosdep update

如果出现如下提示则表示成功！
