我已经安装了 express 和 express-generator 但仍然无法正常工作但是我可以在 node_modules 中看到这两个文件夹
I have installed express and express-generator but still its not working however i can see both the folders in node_modules
安装 express 和 express-generator 后我无法使用 'express' 关键字。
试过这个命令
npm install express
和
npm install express-generator
cmd> express --v
在 cmd 中检查 express --v
时,它应该显示已安装的版本,但我收到以下错误。
express : The term 'express' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of
the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ express --v
+ ~~~~~~~
+ CategoryInfo : ObjectNotFound: (express:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
为了能够在终端中使用 express,您需要全局安装包。
npm i -g express
express
如果您没有全局安装它,那么您只能在您的项目范围内从 package.json 脚本访问它。
