我的express 和 node 都是 全局安装的，用 express nodejs-demo 创建完项目后，也有用 npm install -d 在项目文件夹里关联引用 用 npm start启动后直接报上面这个错了！！

在package.json 里加入 “source-map”:"~0.1.34" npm install后出现下面的错误

npm WARN unmet dependency /home/hw/node/web/nodejs-demo/node_modules/jade/node_modules/with/node_modules/uglify-js requires source-map@‘0.1.34’ but will load npm WARN unmet dependency /home/hw/node/web/nodejs-demo/node_modules/source-map, npm WARN unmet dependency which is version 0.1.37 npm WARN unmet dependency /home/hw/node/web/nodejs-demo/node_modules/jade/node_modules/constantinople/node_modules/uglify-js requires source-map@‘0.1.34’ but will load npm WARN unmet dependency /home/hw/node/web/nodejs-demo/node_modules/source-map, npm WARN unmet dependency which is version 0.1.37
