Mac上安装Node和NPM【转】

作为前端开发者,node和npm安装必不可少。然而有时会因为安装新的app(如MacPorts,慎装,它会修改基本环境变量以及npm的全局设置等)导致版本环境混乱,特别推荐安装brew来对node和npm版本进行管理。
安装brew
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew安装node
- 首先更新brew,使其在最新版本,代码如下:
$ brew update
-
确保brew是安全可靠的,代码如下:
$ brew doctor
将可能导致如下情况,可针对性逐条处理,处理完成放可完成下一步:Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.You should probably
sudo chown -R $(whoami)
them:
/usr/local/share/man/man5
/usr/local/share/man/man7
-
将brew的位置添加到$PATH环境变量中,并保存bash或者profile文件;
export PATH="/usr/local/bin:$PATH"
-
当处理完上述问题后,来处理brew和node关系
若在上文中出现,如下错误信息:Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Runbrew link
on these:
node
则需要如下操作:- 清理brew的link
$ brew cleanup
- 删除node文件,完全卸载node和npm
或者是sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}
或者是下面这样:sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp /opt/local/bin/node opt/local/include/node /opt/local/lib/node_modules
1.在/usr/local/lib目录下,删除任何与node和 node_modules有关的目录; 2.在/usr/local/include 目录下,删除任何与node 和 node_modules有关的目录; 3.如果你是通过**brew install node**安装的node,则在终端执行**brew uninstall node** ,并在home目录下查找 **local** 或**lib** 或 **include**文件夹,删除任何与**node** 和 **node_modules**有关的目录; 4.在**/usr/local/bin**目录下,删除任何与 **node** 执行文件; 5.最后下载 **nvm** ,跟随它的介绍安装node。当然,你也可以通过**npm**来安装最新版本的Node。
- 清理brew的link
-
通过brew安装node和npm
brew link node brew uninstall node brew install node
- 测试Node和npm安装是否成功,安装Grunt
npm install -g grunt-cli
如果安装成功,那么恭喜你node,npm,grunt均安装成功。若出现问题,请回顾前面内容。
