安装节点和npm的问题

我必须安装node和npm。在安装之前,我做了一些搜索安装这些东西的最佳方法。我找到的是:

  1. 安装nvm
  2. 使用node
  3. 安装nvm
  4. 设置nvm alias default,以便默认情况下node可用。
  5. 安装npm时,您还会获得node
  6. 将全局模块目录更改为HOME内的某个路径,以便在使用npm安装全局范围包时,您不必使用sudo。
  7. 使用npm作为全局模块再次安装npm
  8. 将新的全局模块目录bin添加到我们的$PATH环境变量
  9. 但在执行此操作后npm无效。它给出了以下错误:

    $ npm install -g yo
    
    > spawn-sync@1.0.13 postinstall /Users/aapa/.node_modules_global/lib/node_modules/yo/node_modules/cross-spawn/node_modules/spawn-sync
    > node postinstall
    
    /Users/aapa/.node_modules_global/bin/yo -> /Users/aapa/.node_modules_global/lib/node_modules/yo/lib/cli.js
    
    > yo@1.4.7 postinstall /Users/aapa/.node_modules_global/lib/node_modules/yo
    > yodoctor
    
    sh: yodoctor: command not found

    以下是我运行的所有实际命令:

    #1. Install nvm
    $curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.26.1/install.sh | bash
    
    #2. Install node using nvm
    $nvm install node
    # This will install the latest stable version of node. Here `node` is an alias to stable 
    #node -> stable (-> v0.12.7) (default)
    #stable -> 0.12 (-> v0.12.7) (default)
    
    #3. Set the nvm alias default so that the node will be available by default.
    $nvm alias default node
    
    #4. You will also get npm while installing node.
    $ which npm
    /Users/aapa/.nvm/versions/node/v0.12.7/bin/npm
    
    #5. Change the global modules directory to some path inside your HOME so that while installing global scoped packages using npm you don't have to use sudo.
    $ npm config get prefix
    /Users/aapa/.nvm/versions/node/v0.12.7
    $ cd && mkdir .node_modules_global
    $ npm config set prefix=$HOME/.node_modules_global
    $ npm config get prefix
    /Users/aapa/.node_modules_global
    $ cat .npmrc
    prefix=/Users/aapa/.node_modules_global
    
    #6. Install npm again using npm as a global module.
    $ npm install npm --global
    /Users/aapa/.node_modules_global/bin/npm -> /Users/aapa/.node_modules_global/lib/node_modules/npm/bin/npm-cli.js
    npm@2.14.1 /Users/aapa/.node_modules_global/lib/node_modules/npm
    
    #7. Add new global module directory's `bin` to our `$PATH` environment variable
    $ echo -e '\n\n#adding npm global module location to path\nexport PATH="$HOME/.node_modules_global/bin:$PATH"' >> ~/.bash_profile
    $ source ~/.bash_profile
    
    # check
    $ which npm
    /Users/aapa/.node_modules_global/bin/npm
    

    网上还有一些其他相关资源:

    1. SO- NPM permission error while installing - 这里的答案建议使用我要避免使用的sudo
    2. Yeoman issues - can not install yeoman on my mac running OS X Yosemite 10.10.1 - 我认为我已根据此处的解决方案完成了所有操作,但此处的解决方案使用.bashrc而我使用了.bash_profile
    3. 我不确定我做错了什么。有什么想法吗?

我认为最好和最简单的方法是从网站上下载节点:nodejs.org并安装它。

打开cmd之后,从那里转到下载nodejs文件夹并输入

npm install package-name

如果要全局安装,请使用-g like

npm install package-name -g

最简单的解决方案是不要执行第5,6和7步。

缺点是你必须为你正在使用的每个节点版本单独安装全局变量,但听起来你不经常切换版本。
