无法安装和运行 nodemon npm - Nodejs

Question

我无法运行我的 nodejs 项目，出现以下错误。

> restfullnodejs@1.0.0 start C:\Users\PC\restfullnodejs
> nodemon app.js

npm ERR! code ELIFECYCLE
npm ERR! syscall spawn C:\Users\PC\restfullnodejs\git\bin\bash.exe

npm ERR! spawn C:\Users\PC\restfullnodejs\git\bin\bash.exe ENOENT

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我的猜测是 nodemon 的错误，如果是这样，我该如何解决这个问题。也无法安装nodemon

更新 删除 package-lock.json 文件和 nodemodules 文件夹后尝试npm clear cache --force 然后npm install - g nodemon

然后低于错误

Answer 1

这是 PC/Windows 上的常见问题；

试试：

1. 删除 package-lock.json 和 node_modules 文件夹。
2. 从应用的根文件夹运行“npm install”。
3. 运行“npm install -g nodemon”
