Sublime Node.js开发环境配置

下载并安装Node.js安装包后再开始配置

　　1.先安装好Sublime Text 2

　　2.运行Sublime,菜单上找到Tools ---> Build System ---> new Build System

　　3.在文件中复制入

{
    "cmd": ["node", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.javascript"
}

4.保存文件为NodeJs.sublime-build

　　5.菜单上找到Tools ---> Build System --->选择 NodeJs

　　6.安装Package Control；运行Sublime，按下快捷键Ctrl + `；在控制台中输入如下并回车;

sublime Text3
import urllib.request,os,hashlib; h = ‘eb2297e1a458f27d836c04bb0cbaf282‘ + ‘d0e7a3098092775ccb37ca9d6b2e4b7d‘; pf = ‘Package Control.sublime-package‘; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( ‘http://packagecontrol.io/‘ + pf.replace(‘ ‘, ‘%20‘)).read(); dh = hashlib.sha256(by).hexdigest(); print(‘Error validating download (got %s instead of %s), please try manual install‘ % (dh, h)) if dh != h else open(os.path.join( ipp, pf), ‘wb‘ ).write(by)

sublime Text2
import urllib2,os,hashlib; h = ‘eb2297e1a458f27d836c04bb0cbaf282‘ + ‘d0e7a3098092775ccb37ca9d6b2e4b7d‘; pf = ‘Package Control.sublime-package‘; ipp = sublime.installed_packages_path(); os.makedirs( ipp ) if not os.path.exists(ipp) else None; urllib2.install_opener( urllib2.build_opener( urllib2.ProxyHandler()) ); by = urllib2.urlopen( ‘http://packagecontrol.io/‘ + pf.replace(‘ ‘, ‘%20‘)).read(); dh = hashlib.sha256(by).hexdigest(); open( os.path.join( ipp, pf), ‘wb‘ ).write(by) if dh == h else None; print(‘Error validating download (got %s instead of %s), please try manual install‘ % (dh, h) if dh != h else ‘Please restart Sublime Text to finish installation‘)

　　7.安装完成后重新启动Sublime，按下快捷键Ctrl + Shift + P; 输入install，选择Install Package并回车

　　8.输入nodejs并选择Nodejs安装（可以装上JavaScript & NodeJs Snippets）

配置Sublime Node.js开发环境就成功了！

nodejs版本控制  nvmw（Node version manager for Windows）
