NPM脚本问题

Question

I have a nodejs file runner.node.js .

If I run node runner.node.js it works

But if I try tu run it with npm test (it's referenced in package.json):

"test": "node ./spec/runner.node.js"

or

"test": "spec/runner.node.js"

It says that the file isn't executable:

sh: 1: spec/runner.node.js: Permission denied
npm ERR! Test failed.  See above for more details.
npm ERR! not ok code 0

If I set the file as executable it then says:

spec/runner.node.js: 1: spec/runner.node.js: Syntax error: word unexpected (expecting ")")
npm ERR! Test failed.  See above for more details.
npm ERR! not ok code 0

while it still runs correctly with "node spec/runner.node.js"

The file is this:

console.log("Running Knockout tests in Node.js");

var fs = require('fs');
var jasmine = require('./lib/jasmine-1.2.0/jasmine');

// export jasmine globals
for (var key in jasmine) {
    global[key] = jasmine[key];
}

// add our jasmine extensions to the exported globals
require('./lib/jasmine.extensions');

// export ko globals
if (process.argv.length > 2 && process.argv[2] == '--source') {
    // equivalent of  ../build/knockout-raw.js
    global.DEBUG = true;
    global.ko = global.koExports = {};
    global.knockoutDebugCallback = function(sources) {
        sources.unshift('build/fragments/extern-pre.js');
        sources.push('build/fragments/extern-post.js');
        eval(sources.reduce(function(all, source) {
            return all + '\n' + fs.readFileSync(source);
        }, ''));
    };
    require('../build/fragments/source-references');
} else {
    global.ko = require('../build/output/knockout-latest.js');
}

// reference behaviors that should work out of browser
require('./arrayEditDetectionBehaviors');
require('./asyncBehaviors');
require('./dependentObservableBehaviors');
require('./expressionRewritingBehaviors');
require('./extenderBehaviors');
require('./mappingHelperBehaviors');
require('./observableArrayBehaviors');
require('./observableBehaviors');
require('./subscribableBehaviors');

// get reference to jasmine runtime
var env = jasmine.jasmine.getEnv();

// create reporter to return results
function failureFilter(item) {
    return !item.passed();
}
env.addReporter({
    reportRunnerResults:function (runner) {
        var results = runner.results();
        runner.suites().map(function (suite) {
            // hack around suite results not having a description
            var suiteResults = suite.results();
            suiteResults.description = suite.description;
            return suiteResults;
        }).filter(failureFilter).forEach(function (suite) {
            console.error(suite.description);
            suite.getItems().filter(failureFilter).forEach(function (spec) {
                console.error('\t' + spec.description);
                spec.getItems().filter(failureFilter).forEach(function (expectation) {
                    console.error('\t\t' + expectation.message);
                });
            });
        });
        console.log("Total:" + results.totalCount + " Passed:" + results.passedCount + " Failed:" + results.failedCount);
        process.exit(results.failedCount);
    }
});

// good to go
env.execute();

Add

#/usr/bin/env node

as the first line in your file. This way, when run as an executable your OS will know that it shall use Node.js to run it (to be exactly: your OS will know that it shall use the first application called node to execute your script).
