nodejs最新7.8与expressJS坠毁？

Question

从6.9我的节点升级到7.8之后，我明确的应用程序已经突破：

$ nodemon                                             
[nodemon] 1.11.0                                                                
[nodemon] to restart at any time, enter `rs`                                                         
[nodemon] watching: *.*                                                               
[nodemon] starting `node ./bin/www`

     ^

这是什么意思？我该如何解决它？

任何想法？

每次升级Node时都应该重建您的依赖关系。

在您应用的目录中运行npm rebuild或npm install。

您也可以从头开始删除node_module并运行npm install。

这是你在你的问题援引非常错误信息实际上解释说：

Error: The module '/var/www/html/expresss-app/node_modules/bcrypt/build/Release/bcrypt_lib.node' 
was compiled against a different Node.js version using 
NODE_MODULE_VERSION 48. This version of Node.js requires 
NODE_MODULE_VERSION 51. Please try re-compiling or re-installing 
the module (for instance, using `npm rebuild` or`npm install`).
