first of all, you need to make sure that your user exists:

npm config ls

secondly, your package.json must have a name and a version number. I think this should be fine. Then try to install

npm install wflixu

published successfully.
but your screenshot is not installed or searched.

cannot install or search, it should be the package name.

A magical mistake.
originally the command to publish the npm package was
npm publish.
with one less solid point before

1. There is a delay in npm. Let's see if we can find it later.

2. Npm may have made a search limit, which does not exceed a certain number of clicks or downloads. It cannot be found, and can only be found by looking in its own packges.

3. If you upload successfully and want to download the package you uploaded in the new project, remember to npm init your new project, and then npn install < name > bar
