Question

我在windows 64bit中安装了node.js，当我在本地项目上运行时，我遇到了这个问题。

另一个注意事项：npm install在packages.json

中运行良好

Error: Cannot find module 'lodash.assign'

这是我的package.json（我正在尝试设置此项目：https://github.com/MarlabsInc/webapi-angularjs-spa）

这是我的gulp文件：

        ], { read: false })
    .pipe(clean({ force: true }));
});
gulp.task('build', ['app-js-minify', 'libs-js-minify', 'minify-css']);
gulp.task('cleanbuild', ['clean']);

gulp.task('tests', function () {
    connect.server({

    });
    var testUrl = "http://localhost:8000/SpecRunner.html";
    gulp.src("./SpecRunner.html")
      .pipe(open("", { url: testUrl }));
});

//gulp.watch('./app/**/*.js', ['js']);

尝试以下操作：

npm uninstall --save-dev gulp-jshint
npm uninstall --save lodash
npm cache clean
npm install --save-dev gulp-jshint

不确定这是您的情况的问题，但有时节点缓存会混乱并出现类似消息。基本上，lodash 应该在安装该软件包时作为 gulp-jshint 的依赖项安装。除非你直接调用 lodash 的一些方法，否则你应该需要手动安装它。

卸载后清理节点缓存，应从头下载并安装包，修复任何依赖错误。
