npm ERR 404 npm ERR 404 ‘@vue/[email protected]‘ is not in the npm registry.

Here's the thing, I'm going to install the element ui library today, but an error is reported when I type the command.

So I looked for a bunch of tutorials on the Internet, what to replace the npm source, etc., to no avail.

Finally I solved it successfully using the following method!

error

• First open the terminal and enter the following command.

  npm i element-ui -S
  

• Then an error message appears.

  npm WARN deprecated [email protected]: core-js@<3.4 
  is no longer maintained and not recommended for usage due to the number of issues. Because of the 
  V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even 
  if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.

Solution

• So I deleted the entire node_modules.

  Delete the whole thing!

• Then enter the following command.

  npm i element-ui -S
  

• Successful installation.
