npm install failing
提问by Danny
I'll start off by saying that I have next to no experience working in terminal or with node.js.
我首先要说我几乎没有在终端或 node.js 中工作的经验。
Coworker left for vacation and I'm trying to follow instructions he left for setting up his app on our demo server. I can get everything running locally, but am running into issues on the server installing socket.io module.
同事去度假了，我正在尝试按照他留下的说明在我们的演示服务器上设置他的应用程序。我可以让一切都在本地运行，但是在安装 socket.io 模块的服务器上遇到了问题。
Installed python, installed nodejs, both successful. But then I issue the command:
安装python，安装nodejs，都成功了。但后来我发出命令：
npm install -g socket.io
And the output I get is:
我得到的输出是：

The account I'm on should have admin privileges. Googling around I found some suggestions but none seemed to work for me. Tried prepending command with sudo but get:
我所在的帐户应该具有管理员权限。谷歌搜索我发现了一些建议，但似乎没有一个对我有用。尝试使用 sudo 预置命令，但得到：
[qa@umr-demo ~]sudo npm install -g socket.io
[sudo] password for qa:
sudo: npm: command not found

I have the same error if not privileged, so I must use sudo when using the -gflag
如果没有特权，我也有同样的错误，所以在使用-g标志时我必须使用 sudo
If sudo don't recongize npm you can try:
如果 sudo 不认识 npm，您可以尝试：
passing the complete route of npm
$ sudo $(which npm) install -g socket.iopreserving the environment with -E flag
$ sudo -E npm install -g socket.io
通过npm的完整路线
$ sudo $(which npm) install -g socket.io使用 -E 标志保护环境
$ sudo -E npm install -g socket.io
Upd:
更新：
Note that is recommended to use the -gflag only for executablesand install locally (without the flag) the libraries that are required in your code. Privileges are required for copying the executables to /usr/binor, in your case /usr/local/bin
请注意，建议仅将-g标志用于可执行文件，并在本地（不带标志）安装require代码中的库。将可执行文件复制到/usr/bin或在您的情况下需要特权/usr/local/bin
Note too that in the socket.io site, the -gflag is not included for the installation command ;)
还要注意，在 socket.io 站点中，-g安装命令不包含该标志；)

If you are on Arch Linux, check out the npm2archpackage in the AUR. It will let you install npm packages using pacman.
如果您使用的是 Arch Linux，请查看npm2archAUR 中的软件包。它将让您使用 pacman 安装 npm 包。
Example:
例子：
npm2archinstall socket.io
