0. 提前新建好数据库 beijing 并安装以下3个扩展
create extension hstore;
create extension postgis;
create extension pgrouting;
1. 准备好 osmosis 工具和 osm2pgrouting 工具
2. cmd 一定是管理员
cd "C:Program Files (x86)osmosisin"
C:Program Files (x86)osmosisin>osmosis --read-pbf "D:dataeijing.osm.pbf" --write-xml beijing.osm
3. osm2pgrouting 只接受.osm 不接受.osm.pbf二进制文件
cd D:data
osm2pgrouting --file D:/data/beijing.osm --conf S:/PostgreSQL/10/bin/mapconfig_for_cars.xml --schema public --addnodes --prefix bj_ --suffix _car --clean -d beijing -U postgres -h localhost -p 5432 -W jiangshan
or 以下带全部参数
osm2pgrouting --file D:/data/beijing.osm --conf S:/PostgreSQL/10/bin/mapconfig_for_cars.xml --schema public --prefix bj_ --suffix _car --addnodes --attributes --tags --clean -d beijing -U postgres -h localhost -p 5432 -W jiangshan
正常应该输出以下：

Processing Points of Interest ...
Adding functions for processing Points of Interest ...
To process pointsOfInterest table:
osm2pgr_pois_update(radius default 200, within default 50)
- Using areas of (radius)mts on POIS
- Using edges that are at least (within) mts of each POI
POIS that do not have a closest edge is considered as too far
