当我运行节点时，什么也没发生，永远一样

Question

I installed both node.js and forever.js and when I run them in my terminal (bash on Ubuntu 14.04), nothing happens.

So, it looks like:

#node
#

or

#forever
#forever --help
#forever listall
#

Everything else not node-related runs fine.

Answer 1

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.

I uninstalled it with

apt-get purge node

Then, I downloaded the 64-bit linux binary from here: http://nodejs.org/download/

And I extracted it with tar -xvf filename , then I set that directory/bin to the path with:

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.

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 node with apt-get is apt-get install nodejs .

Answer 2

I had the same issue, and I think it was caused because I naively apt-get installed node first. Doing a

sudo apt-get purge node

Followed by the instructions on the web here ( 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. node doesn't exist, but nodejs does and other tools work (like slap ) now.

EDIT: On one server I updated, node did exist. Not sure exactly what order things need to happen in, but whatever...

我遇到了这个问题，我发现要解决该问题，我需要删除/ usr / sbin / node（找到which node ）内的节点文件，并用到/ usr / bin / nodejs的硬链接（找到用which nodejs ）

ln /usr/bin/nodejs /usr/sbin/node

Answer 4

Just run nodejs command on your terminal after installing nodejs package.

It will give you the JavaScript prompt or interpreter.

Answer 5

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.

To verify this you can do a

% which forever
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.

% 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.

But to bypass this problem you should definitely look into using upstart. http://howtonode.org/deploying-node-upstart-monit
