在 PyCharm 中创建 node.js app 的时候报告 Express version is unavailable 错误求解 ~

可以贴上你的package.json文件？

参考 http://delbert.me/archives/719.html ,我觉得你应该用
$ npm install -g express-generator@4
或
$ npm install -g express-generator
这个命令。

@StevenSLXie 这是 npm/package.json 文件，@Delbert 依旧是不行。。。

看来LZ确实是新手。

错误提示是在「创建」“Express App”的时候提示的吗？

其实你也可以直接创建不带模板的node app。然后去项目目录里，用npm link express命令把全局下的那个express库给link到本地目录

为啥不用webstorm?

你需要的是Webstorm

@blueandhack
@ityao 因为已经购买了 PyCharm 的个人版。。。
