我必须安装节点和npm。在安装之前，我做了一些搜索以安装这些东西的最佳方式。我发现是：安装节点和npm的问题
- 安装
nvm - 使用
nvm - 设置
nvm alias default使得node将可通过默认安装node。 - 在安装
node时，您还将获得npm。 - 将全局模块目录更改为
HOME中的某个路径，以便在安装全局作用域使用npm的程序包时，不必使用sudo。 - 再次使用
npm作为全局模块安装npm。 - 添加新的全局模块目录的
bin我们$PATH环境变量
但这样做npm不工作后。它给予以下错误：
$ npm install -g yo

这里是所有我遇到的实际命令：
#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
[email protected] /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
也有对网络的一些其他相关资源：
- SO- NPM permission error while installing - 建议在这里的答案使用我试图避免的
sudo。 - Yeoman issues - can not install yeoman on my mac running OS X Yosemite 10.10.1 - 我想我已经完成了所有的解决方案，除了这里的解决方案使用了
.bashrc和我已经使用了.bash_profile。
我不知道我在哪里做错了。有任何想法吗？
