When I run node, nothing happens, the same with forever
提问by JVE999
I installed both node.js and forever.js and when I run them in my terminal (bash on Ubuntu 14.04), nothing happens.
我安装了 node.js 和forever.js，当我在终端（Ubuntu 14.04 上的bash）中运行它们时，没有任何反应。
So, it looks like:
所以，它看起来像：
#node
#
or
或者
#forever
#forever --help
#forever listall
#
Everything else not node-related runs fine.
其他与节点无关的一切都运行良好。

There was something wrong with apt-get, so when installing node, it didn't actually install node, but it did put a program in the path that did seemingly nothing.
有问题apt-get，所以在安装 node 时，它实际上并没有安装 node，但它确实在路径中放置了一个看似什么都没做的程序。
I uninstalled it with
我卸载了它
apt-get purge node
apt-get purge node
Then, I downloaded the 64-bit linux binary from here: http://nodejs.org/download/
然后，我从这里下载了 64 位 linux 二进制文件：http: //nodejs.org/download/
And I extracted it with tar -xvf filename, then I set that directory/binto the path with:
我用 提取它tar -xvf filename，然后我将它设置directory/bin为路径：
PATH=$PATH:/directory/to/node/bin
PATH=$PATH:/directory/to/node/bin
And now it works fine. The forever issue was because the node installed wasn't node at all, but instead a 30kb program of some sort, I don't know.
现在它工作正常。永远的问题是因为安装的节点根本不是节点，而是某种 30kb 的程序，我不知道。
Here's the information about the program that was installed via apt-get install node:

So, I also found that the correct way to install nodewith apt-getis apt-get install nodejs.
所以，我也发现，安装正确的方式node与apt-get是apt-get install nodejs。

I had the same issue, and I think it was caused because I naively apt-get installed node first. Doing a
我遇到了同样的问题，我认为这是因为我先天真地 apt-get 安装了节点。做一个
sudo apt-get purge node
Followed by the instructions on the web here (https://github.com/nodesource/distributions):
后面是网上的说明（https://github.com/nodesource/distributions）：
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs
fixed the issue for me. nodedoesn't exist, but nodejsdoes and other tools work (like slap) now.
为我解决了这个问题。 node不存在，但现在nodejs和其他工具一起工作（如slap）。
EDIT: On one server I updated, node didexist. Not sure exactly what order things need to happen in, but whatever...
编辑：在我更新的一台服务器上，节点确实存在。不确定事情需要按什么顺序发生，但无论如何......

I was having this issue, I found that to solve the issue, I needed to remove the node file within /usr/sbin/node (found with which node) and replace it with a hard link to /usr/bin/nodejs (found with which nodejs)
我遇到了这个问题，我发现要解决这个问题，我需要删除 /usr/sbin/node 中的节点文件（用 找到which node）并将其替换为指向 /usr/bin/nodejs 的硬链接（用 找到which nodejs）
ln /usr/bin/nodejs /usr/sbin/node
ln /usr/bin/nodejs /usr/sbin/node

Just run nodejscommand on your terminal after installing nodejs package.
nodejs安装 nodejs 包后，只需在终端上运行命令。
It will give you the JavaScript prompt or interpreter.
它将为您提供 JavaScript 提示或解释器。
回答by Marek
The problem you are having is that apt-get installed NodeJS under the binary nodejs. Also when you do a npm install forever -g it also expects the binary to be node.
您遇到的问题是 apt-get 在二进制 nodejs 下安装了 NodeJS。此外，当您永远执行 npm install -g 时，它还希望二进制文件为 node.js。
To verify this you can do a
要验证这一点，您可以执行以下操作
% which forever
lrwxrwxrwx 1 root root 39 Jan 25 21:34 /usr/local/bin/forever -> ../lib/node_modules/forever/bin/forever
% which永远
lrwxrwxrwx 1 root root 39 Jan 25 21:34 /usr/local/bin/forever -> ../lib/node_modules/forever/bin/forever
to find the location of the forever script. Then check the node binary it's trying to execute.
找到永久脚本的位置。然后检查它试图执行的节点二进制文件。
% vim /usr/local/lib/node_modules/forever/bin/forever
#!/usr/bin/env node
% vim /usr/local/lib/node_modules/forever/bin/forever
#!/usr/bin/env node
This /usr/bin/env node needs to be changed to /usr/bin/env nodejs.
这个/usr/bin/env节点需要改成/usr/bin/env nodejs。
But to bypass this problem you should definitely look into using upstart. http://howtonode.org/deploying-node-upstart-monit
但是要绕过这个问题，你绝对应该考虑使用 upstart。 http://howtonode.org/deploying-node-upstart-monit
