这是我尝试执行此命令时得到的结果（第3个命令 - 在ec2亚马逊中）
The next step is to install NPM(Node package manager). Type the following commands:
1. git clone https://github.com/isaacs/npm.git
2. cd npm
**3. sudo make install**
这是我得到的错误：
[ec2-user@ip-172-31-44-20 npm]$ sudo make install
scripts/doc-build.sh doc/api/npm-view.md man/man3/npm-view.3
