问题 To give some context, I set up my machine using this Medium post, Don’t Use sudo with npm …still. I installed Node using brew about a year and a half ago, which installed v12.18.1. I also installed n at the time using brew , but never had to change versions until now. My .zshrc file includes the following: # For globally installed npm packages (without using sudo) export PATH="$HOME/.npm/bin:$PATH" # Path to n (managing node versions) export N_PREFIX="$HOME/.n" export PATH="$PATH:$N_PREFIX

问题 I would like to install NodeJS version 0.8.18 on Ubuntu 12.04. I tried to install the newest version and then reverting to 0.8.18 by using nvm , but when I run my code apparently there is some problem with the packages installed and the two versions (latest and 0.8.18). Since I don't know how to solve that problem, I cleaned the machine from the Node installation and thought about installing directly the version I'm interested in (v0.8.18). 回答1: Chris Lea has 0.8.23 in his ppa repo.

日常工作中,经常要查询分组的前几名或查询数据的前几条记录（第5条到第十条）等。 TOP-N分析法就是通过TOP-N算法从研究对象中得到所需的N个数据，并从排序列表中选取最大或最小的N个数据，这就是一个TOP-N算法。 mysql中用limit；oracle中用rownum。 mysql中 没有top ， 你想查前几条数据 要用排序方试来查 order by id desc limit 0,10 按照id的倒序排序 取出前10条 order by id limit 5,10 按照id的正序排序 从第5条开始取10条 从mysql到oracle迁移一个程序，遇到了sql语句中的limit问题。 查遍网络，所提供的方法都极其麻烦，不利于通用。 以下是我的解决方案，可以与limit媲美。 比如从一个mobileuser 用户表中查询2到6条记录，按照第一次使用时间排序。 mysql语句为： SELECT userid,password,firstusetime from mobileuser ORDER BY firstusetime DESC limit 2,6; oracle语句为： SELECT * FROM ( SELECT userid,password,firstusetime, RANK() OVER (ORDER BY firstusetime DESC ) RN FROM
