npm WARN deprecated lodash@2.4.2: lodash@<3.0.0 is no longer maintained

Question

I'm getting an error when using npm to install grunt-cli globally. It's related to lodash:

npm WARN deprecated lodash@2.4.2:
lodash@<3.0.0 is no longer maintained. Upgrade to lodash@^3.0.0.

---

Here are the versions i'm using, and the list of global packages installed.

node: v5.1.0

npm: v3.5.0

npm list -g: http://pastebin.com/NuJU3bY0

I've attempted to install the latest version of lodash (v3.10.1) globally, but I still got the error again after uninstalling my grunt-cli global package, and then re-installing my global package. Below is the installation log:

sudo npm install lodash -g
/usr/local/lib
└── lodash@3.10.1

sudo npm install grunt-cli -g
npm WARN deprecated lodash@2.4.2: 
lodash@<3.0.0 is no longer maintained. Upgrade to lodash@^3.0.0.

Can anyone tell me what i'm doing wrong, or how to fix this error and get a clean install of grunt-cli?

Answer 1

The packagegrunt-cli relies on a older version of lodash. It shouldn't affect the functionality of grunt; it's just a warning message.

So, you're doing nothing wrong, it's not an error message, just a warning, and the way you've installed grunt-cli should work fine.

Answer 2

You can try running this command in your console:

npm i -g lodash

Let me know if this fixes it.
