Linux NodeJS全局NPM包“：没有这样的文件或目录”

Question

I am using Ubuntu 14.04 and have installed nodejs and npm with:

sudo apt-get install nodejs npm

Then I made a symlink to enable packages to use the node interpreter (instead of nodejs ):

sudo ln -s /usr/bin/nodejs /usr/local/bin/node

I installed coffee-script (for testing purposes) and my own package, mangarack , with:

sudo npm -g install coffee-script mangarack

When I run coffee (part of coffee-script ), that package will run fine. If I run mangarack , I will get:

: No such file or directory.

I have the following in my package.json :

"bin": {
  "mangarack": "./bin/mangarack"
},

And that file contains:

#!/usr/bin/env node

require('../lib/cli/index');

I looked at how coffee-script did it and it seems like my require statement is absolutely wrong, so I replaced that with a console.log statement to see if the file would actually run in node . It doesn't. What did I miss or miss-configure to enable Linux-based machines to run this package?

The problem is the file bin/mangarack uses carriage return, which causes error in linux environment. see what I got:

$ mangarack --help
env: node\r: No such file or directory

$ head -n 1 `which mangarack` | hexdump
0000000 23 21 2f 75 73 72 2f 62 69 6e 2f 65 6e 76 20 6e
0000010 6f 64 65 0d 0a
0000015

Notice the character \\r ( 0d in hex mode) after node . you should remove it.

Solution: setup your project with $ git config core.autocrlf then commit changes afterwards. see https://help.github.com/articles/dealing-with-line-endings/

the expected result after fix should be:

$ head -n 1 `which mangarack` | hexdump
0000000 23 21 2f 75 73 72 2f 62 69 6e 2f 65 6e 76 20 6e
0000010 6f 64 65 0a
0000015
