How can I add npm (node.js package manager) to the PATH?
提问by emurad
I installed node.js like this:
我像这样安装了 node.js：
cd /usr/local/bin/
git clone --depth 1 http://github.com/joyent/node.git
cd node
git checkout origin/v0.4 # optional. Note that master is unstable.
export JOBS=2 # optional, sets number of parallel commands.
mkdir ~/local
./configure --prefix=$HOME/local/node
make
make install
echo 'export PATH=$HOME/local/node/bin:$PATH' >> ~/.profile
source ~/.profile
Then I executed this curl http://npmjs.org/install.sh | shto install npm. After I logged out and logged back in, npm command wasn't recognized:
然后我执行这个curl http://npmjs.org/install.sh | sh来安装npm。注销并重新登录后，无法识别 npm 命令：
[/usr/local/bin/node]# npm install now
-bash: npm: command not found
What should I add to the PATH to have npm working?

I use centos7, and do you know yum (a tool could download and setup programs like mirosoft Windows)
我用的是centos7，你知道yum吗（一个可以下载安装mirosoft Windows之类的程序的工具）
First, I search keyword "node.js" at wiki.centos, I find this. https://wiki.centos.org/SpecialInterestGroup/SCLo/CollectionsList?highlight=%28node.js%29. There are two versions of nodejs could be used at the moment, I chose the higher one. the URL is https://www.softwarecollections.org/en/scls/rhscl/rh-nodejs4/and the command lines are below:
首先，我在 wiki.centos 上搜索关键字“node.js”，我找到了这个。https://wiki.centos.org/SpecialInterestGroup/SCLo/CollectionsList?highlight=%28node.js%29。目前有两个版本的nodejs可以使用，我选择了较高的一个。URL 是https://www.softwarecollections.org/en/scls/rhscl/rh-nodejs4/，命令行如下：
# Install a package with repository for your system:
# On CentOS, install package centos-release-scl available in CentOS repository:
$ sudo yum install centos-release-scl-rh
# On RHEL, enable RHSCL repository for you system:
$ sudo yum-config-manager --enable rhel-server-rhscl-7-rpms
# 2. Install the collection:
$ sudo yum install rh-nodejs4
# 3. Start using software collections:
$ scl enable rh-nodejs4 bash
