Javascript Question

Node project works locally but fails when installing via NPM?

I have this straightforward node project, with a

main.js
file when I run it locally
node main.js
it works fine. But when I do an
npm install -g cli-tweet
and then try to run it, it outputs this error :

/home/USER/.npm-global/bin/tweet: 1: /home/USER/.npm-global/bin/tweet: Syntax error: "(" unexpected


The
package.json
looks something like this :

{
"name": "cli-tweet",
"main": "main.js",
"bin": {
"tweet": "main.js"
},
[...]
}


Any idea on how to fix this ?

Edit 1:



The code for main.js

var OAuth = require('oauth').OAuth,
colors = require('colors'),
Twitter = require('twitter'),
fs = require('fs'),
get_args = require('cli-pipe');

var CONFIG_FILE = '.tweet.json',
REQUEST_TOKEN_URL = 'https://api.twitter.com/oauth/request_token',
ACCESS_TOKEN_URL = 'https://api.twitter.com/oauth/access_token',
OAUTH_VERSION = '1.0', HASH_VERSION = 'HMAC-SHA1';

var key = "XYZ",
secret = "XYZ", tweetText;

function getAccessToken(oa, oauth_token, oauth_token_secret, pin) {
oa.getOAuthAccessToken(oauth_token, oauth_token_secret, pin,
function (error, oauth_access_token, oauth_access_token_secret, results2) {
if (error && parseInt(error.statusCode) == 401) {
throw new Error('The pin number you have entered is incorrect'.bold.red);
}
var keys = {
'ACCESS_TOKEN_KEY': oauth_access_token,
'ACCESS_TOKEN_SECRET': oauth_access_token_secret
};
fs.open(CONFIG_FILE, "wx", function (err, fd) {
try {
fs.close(fd, function (err) {
});
} catch (e) {
}
});
fs.writeFileSync(CONFIG_FILE, JSON.stringify(keys));
console.log('Try echo "test" | cli-tweet'.cyan);
process.exit(1);
});
}

function getRequestToken(oa) {
oa.getOAuthRequestToken(function (error, oauth_token, oauth_token_secret, results) {
if (error) {
throw new Error(([error.statusCode, error.data].join(': ')).bold.red);
} else {
console.log(('https://twitter.com/oauth/authorize?oauth_token=' + oauth_token).underline.blue)
console.log('Enter the pin number here:'.bold.yellow);
var stdin = process.openStdin();
stdin.on('data', function (chunk) {
var pin = chunk.toString().trim();
getAccessToken(oa, oauth_token, oauth_token_secret, pin);
});
}
});
}

function tweet(userTokens) {
var client = new Twitter({
consumer_key: key,
consumer_secret: secret,
access_token_key: userTokens.oauth_access_token,
access_token_secret: userTokens.oauth_access_token_secret
});
console.log("Tweet :" + tweetText.bold.cyan);
if (tweetText.length > 0) {
client.post('statuses/update', {status: tweetText}, function (error, tweet, response) {
if (error) {
console.log("Error :" + JSON.stringify(error));
}
process.exit(1);
});
} else {
console.log("Pipe a tweet".bold.red);
}
}

var isConfig = process.argv[2];
if (isConfig === undefined || isConfig.toLowerCase() != "config") {
try {
var contents = fs.readFileSync(CONFIG_FILE).toString(), tokens = JSON.parse(contents);
} catch (e) {
console.log("Error: Try running 'tweet config' command".bold.red);
}
if (tokens != undefined && (tokens.ACCESS_TOKEN_KEY != undefined && tokens.ACCESS_TOKEN_SECRET != undefined)) {
try {
get_args(function (args) {
tweetText = args[2];
tweet({
"oauth_access_token": tokens.ACCESS_TOKEN_KEY,
"oauth_access_token_secret": tokens.ACCESS_TOKEN_SECRET
});
});
} catch (e) {
console.log("Error: Unexpected error while tweeting".bold.red);
}
} else {
console.log("Try running 'cli-tweet config' command".bold.red);
}
} else {
var oa = new OAuth(REQUEST_TOKEN_URL, ACCESS_TOKEN_URL, key, secret, OAUTH_VERSION, 'oob', HASH_VERSION);
getRequestToken(oa);
}


Edit 2 :



Running the code like this:
node /home/USER/.npm-global/lib/node_modules/cli-tweet/main.js
seems to work

Answer

1) Add folder bin

2) Add file bin/tweet with

#!/usr/bin/env node
require('../main.js');

3) change package.json

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