错误：找不到模块“wrench”，当我运行gulp命令时出现此错误。

Question

我在本地和全局都安装了npm、bower和gulp。但是，在运行该文件夹中的gulp时，仍然出现以下错误：

Error: Cannot find module 'wrench'  
at Function.Module._resolveFilename (module.js:325:15)  
at Function.Module._load (module.js:276:25)  
at Module.require (module.js:353:17)  
at require (internal/module.js:12:17)  
at Object.<anonymous> (/home/myPC/documents/workspace/frontend/gulpfile.js:10:14)  
at Module._compile (module.js:409:26)  
at Object.Module._extensions..js (module.js:416:10)

at Function.Module._load (module.js:300:12)  
at Module.require (module.js:353:17)  
at require (internal/module.js:12:17)  

这是我的gulpfile.js文件

'use strict';  

var gulp = require('gulp');  
var wrench = require('wrench');  


wrench.readdirSyncRecursive('./gulp').filter(function (file)  
{
    return (/\.(js|coffee)$/i).test(file);  
}).map(function (file)  
{
    require('./gulp/' + file);  
});  


gulp.task('default', ['clean'], function ()  
{  
    gulp.start('build');  
});

这是我的package.json文件

扳手可能未正确安装。您能否手动安装并尝试执行？ - Optimworks

谢谢你的解决方案，现在它可以工作了。我删除了整个目录并逐个安装了所有依赖项。现在它可以工作了。 - Rajath M S

Answer 1

重新在本地安装它。 运行 npm install --save-dev wrench。 有时删除 node_modules 文件夹并运行 npm install 可以解决这种错误。

Answer 2

在这种情况下不需要做任何事情，只需重新运行

"npm install"

Answer 3

我在开始时遇到了同样的问题，所以我运行了上述命令。

npm install --save-dev wrench

后来我发现还有很多其他缺失的组件，最终我意识到我的npm版本过旧，于是我使用以下命令将npm升级到最新版本

sudo npm i npm@latest -g 

然后一切顺利。
