php – Laravel npm安装获取警告 – npm WARN弃用了graceful-fs

我是Laravel的新手,所以我想请一些帮助.我正在跟随Laracasts在how to manage css and js的训练.

当我尝试运行npm install时,我会收到一些警告

npm WARN安装无法安装可选依赖项：不支持

我也试着用npm install -global gulp安装gulp,但是我明白了

npm WARN deprecated graceful-fs@3.0.8: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.
npm WARN deprecated lodash@1.0.2: lodash@<3.0.0 is no longer maintained. Upgrade to lodash@^4.0.0.
npm WARN deprecated graceful-fs@1.2.3: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

所以基本上如果我尝试运行gulp命令,我会从命令行找到No命令’gulp’.

任何想法如何解决这一问题？

只是一些额外的信息：我在vm Ubuntu 14.04上,我的node.js和npm版本是：

node -v
v5.4.1

npm -v
3.3.12

这是我尝试运行npm install时遇到的错误–global gulp

解决方法:

这个npm WARN checkPermissions缺少对/usr/local/lib / node_modules的写访问权清楚地表明你正在运行的用户npm install –global gulp with没有对/usr/local/lib / node_modules的写访问权.请确保您具有正确的写入权限 – 如评论https://docs.npmjs.com/getting-started/fixing-npm-permissions中所述
