警告:找不到PhantomJS

Question

我已经在debian 6上安装了nodejs 0.10.15。

sudo npm install grunt-cli -g

我还在本地测试目录中执行了necessary (将必要的依赖项下载到node_modules目录)，其中包含以下package.json文件：

{
  "name": "sample-name",
  "version": "1.4.0",
  "devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-qunit": ">0.0.0",
    "grunt-qunit-istanbul": ">0.0.0"
  }
}

以下是安装幻影is时的输出：

...
Writing location.js file
Done. Phantomjs binary available at /home/myuser/Test/node_modules/grunt-contrib-qunit/node_modules/grunt-lib-phantomjs/node_modules/phantomjs/lib/phantom/bin/phantomjs

grunt@0.4.1 node_modules/grunt
├── which@1.0.5
...

但是，当我从测试dir运行grunt测试时，我得到：

Running PhantomJS...ERROR

如果我运行安装在前面指定位置的幻影If脚本，就会得到退出代码127 (指示问题路径:http://tldp.org/LDP/abs/html/exitcodes.html)。如果我禁止使用幻影bash脚本，它看起来如下所示：

#!/usr/bin/env node

var path = require('path')
var spawn = require('child_process').spawn

var binPath = require(path.join(__dirname, '..', 'lib', 'phantomjs')).path

var args = process.argv.slice(2)

// For Node 0.6 compatibility, pipe the streams manually, instead of using
// `{ stdio: 'inherit' }`.
var cp = spawn(binPath, args)
cp.stdout.pipe(process.stdout)
cp.stderr.pipe(process.stderr)
cp.on('exit', process.exit)

process.on('SIGTERM', function() {
  cp.kill('SIGTERM')
  process.exit(1)
})

据我所知，这意味着幻影在节点内执行。如果启动节点，输入路径var，就会得到：

:~$ env node
> var path = require('path')
undefined
> 

(我理解为默认行为：node.js displays "undefined" on the console)

有进一步调试此问题的建议吗？

Answer 1

试着跑

npm uninstall phantomjs

然后跑

npm install phantomjs -g

这应该确保幻影安装在命令行中，这样grunt就可以使用它了，还应该确保它安装得很干净。

Answer 2

尝试在您的终端中运行以下命令：

npm install phantomjs-prebuilt@2.1.14 --ignore-scripts

Answer 3

试试npm install grunt-mocha -D
