var path = require(‘path’); var childProcess = require(‘child_process’); var Q = require(‘q’); var phantomjs = require(‘phantomjs’); var binPath = phantomjs.path; … childProcess.execFile(binPath, childArgs, function (err, stdout, stderr) { console.log(stdout); console.log(stderr);
// handle results
deferred.resolve();
}); 这段代码中binPath，也就是phantomjs.path是空的，线上服务器的phantomjs通过npm安装了，但是就是为null，完全不知道怎么办。因为我是搞java的，公司这个是之前遗留的系统，现在一脸懵逼求各位大神帮忙下，感激不尽！！！
官方案例 ： Running via node
The package exports a path string that contains the path to the
phantomjs binary/executable.
Below is an example of using this package via node.
var path = require('path')
var childProcess = require('child_process')
var phantomjs = require('phantomjs-prebuilt')
var binPath = phantomjs.path
var childArgs = [
path.join(__dirname, 'phantomjs-script.js'),
'some other argument (passed to phantomjs script)'
]
childProcess.execFile(binPath, childArgs, function(err, stdout, stderr) {
// handle results
})
或者。。。
to see : https://github.com/Medium/phantomjs 去看源码18行 => https://github.com/Medium/phantomjs/blob/master/lib/phantomjs.js#L18
/**
* Where the phantom binary can be found.
* @type {string}
*/
try {
var location = require('./location')
exports.path = path.resolve(__dirname, location.location)
exports.platform = location.platform
exports.arch = location.arch
} catch(e) {
// Must be running inside install script.
exports.path = null
}
你可以把 catch 的 e 打出来看看是什么错误
@KingTree 打印出来是这样的
{ Error: Cannot find module './location’ at Function.Module._resolveFilename (module.js:469:15) at Function.Module._load (module.js:417:25) at Module.require (module.js:497:17) at require (internal/module.js:20:19)
