Webstorm 无法在 Windows 和 Ubuntu 上识别节点 Express

Question

环境：

Webstorm v10.0.4
Node.js v0.12.5
Windows 8.1
Ubuntu 14.04

如下图所示，在创建'Node.js Express App'的面板上，Webstorm只找到Node和npm，无法识别Express。当然 Express 是全局安装的，我可以在终端上通过 express-generator 创建一个 Express 项目。

➜  ~  npm -g list -depth=0
/usr/local/lib
├── bower@1.4.1
├── cheerio@0.19.0
├── express@4.13.0
├── express-generator@4.12.4
├── npm@2.11.2
└── nrm@0.2.5

和idea.log如下，不是详细消息：

此问题在 Ubuntu 和 Windows 上均出现。
感谢您的帮助！

如下图，我用nrm到select最快的npm镜像——淘宝，Webstorm就出问题了。当改回 npm' main repository,Webstormcan fetchexpress-generator` info 时，一切正常。奇怪！

Answer 1

最初，WebStorm 在临时目录中安装指定版本的 express-generator 包。然后 WebStorm 使用它来生成一个新的 Express 项目。 WebStorm 不使用已安装的 express 或 express-generator 包。

顺便说一句，express-generator 总是在本地将 express 包安装到新项目中，因此已经安装的 express 包无论如何都不能重复使用。

根据截图，问题出在Version: Unavailable（express-generator的版本）。应在对话框底部的 CSS 组合框下方指定原因。不确定，但可能是由于缺少 Internet 连接造成的。可以在 idea.log（在主菜单 "Help | Show Log in Explorer" 上）中找到更详细的错误描述。

Answer 2

我在寻找解决方案时偶然发现了这个问题。我的是 'package.json' 文件中的语法错误。在主项目目录或 Program Files 中的节点安装中。 IDE 没有标记错误，它只是声明它的 'Unavailible'.

要解决此问题，请执行以下操作，打开 CMD - 在节点安装文件夹中，删除 package.json 和 node_modules 文件夹。（确保备份非默认的，以便您可以取回它们）然后运行：

npm init

这将初始化 npm 并恢复默认包和 package.json。这将反过来恢复 express-generator。
