脚本在Webstorm中失败，但不是在终端上失败 [英] Script fails in Webstorm but not from terminal

问题描述

我有一个使用phantomjs-node抓取网页的nodejs脚本.当我从终端窗口运行时，它运行良好，但是当我通过Node JS应用程序的运行配置从Webstorm内部运行时，效果不佳.

I have a nodejs script that uses phantomjs-node to scrape a webpage. It works fine when I run from a terminal window, but not when I run from inside Webstorm via a run configuration for a Node JS application.

什么可能导致Webstorm中的错误?

What could be causing the error in Webstorm?

在注释掉.bash_profile的内容之后，我已经尝试从终端运行脚本，并且该脚本仍然有效.我还检查了另一个示例脚本中的process.env的内容，发现Webstorm与终端中的值完全不同.

I've already tried running the script from the terminal after commenting out the contents of .bash_profile and it still works. I've also checked the contents of process.env in another sample script and saw that the values are completely different in Webstorm vs. terminal.

脚本:

var phantom = require('phantom');
phantom.create(function(ph) {
    return ph.createPage(function(page) {
        return page.open("http://www.google.com", function(status) {
            console.log("opened google? ", status);
            return page.evaluate((function() {
                return document.title;
            }), function(result) {
                console.log('Page title is ' + result);
                return ph.exit();
            });
        });
    });
});

端子输出(效果很好！):

Terminal output (works great!):

opened google?  success
Page title is Google

Webstorm控制台输出(失败):

Webstorm console output (fails):

/usr/local/bin/node phantom.js
phantom stderr: execvp(): No such file or directory


Process finished with exit code 0

推荐答案

Webstorm确实设置了PATH变量，但它与您的应用程序在终端中运行时获得的PATH变量不同.我的解决方案是黑客:

Webstorm does set a PATH variable, but it's different to the PATH variable your app gets when run in the terminal. My solution, a hack:

1. 键入node进入REPL
2. 运行process.env
3. 复制PATH值的内容
4. 向Webstorm添加一个使用此值的名为PATH的环境变量.它将覆盖Webstorm为您的应用提供的默认PATH变量.

1. Type node to get to the REPL
2. Run process.env
3. Copy the contents of the PATH value
4. Add an environment variable to Webstorm called PATH that uses this value. It will overwrite the default PATH variable that Webstorm gives your app.

完成！
