<p>Have the same issue with upgrading. In my case, the package itself doesn't appear in my <code>composer.json</code>. It does appear in my <code>composer.lock</code> file thought. </p>

<p><strong>Edit:</strong> Removing the <code>composer.lock</code> and doing a fresh install fixed this issue for me. The package was a dependency for SEOmatic, but removing SEOmatic didn't remove it from my lock file.</p>

<p>Solved:
removed   "craftcms/vue-asset": "1.0.2"
and changed craftcms version number.
I also had to manually change a few required items as phpstorm seemed to be reverting their versions creating more problems</p>

Yes i had a few quirks with SEOmatic as i accidentally upgraded production db then synced it to local and ran into troubles. Probably the worst experience after a few years using craft so once a blue moon is not all bad. I think the blitz vendor folder is a good way to go in future.

<p>I'm in a multi config env, local, staging &amp; production. I sync my databases down to local then usually update locally, then push to staging and check again before going live.</p>

<p>The recent 3.1 updates aren't working for me.
Usually, I go thru the control panel and all is fine. </p>

<p>Now I get the below. Minor issues for plugins I can usually sort out but how do I solve this one?</p>

Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.

This likely an issue in your composer.json file. Can you edit the original question to share it?

Can't update to 3.1.x
# Can't update to 3.1.x

(Asked by: username_0 on 2019-01-21)

I'm in a multi config env, local, staging & production. I sync my databases down to local then usually update locally, then push to staging and check again before going live.
The recent 3.1 updates aren't working for me.
Usually, I go thru the control panel and all is fine. 
Now I get the below. Minor issues for plugins I can usually sort out but how do I solve this one?

- Installation request for craftcms/vue-asset 1.0.2 -> satisfiable by craftcms/vue-asset[1.0.2].

Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.

### Answer by username_2 on 2019-01-24. Score: 2

Have the same issue with upgrading. In my case, the package itself doesn't appear in my `composer.json`. It does appear in my `composer.lock` file thought.

**Edit:** Removing the `composer.lock` and doing a fresh install fixed this issue for me. The package was a dependency for SEOmatic, but removing SEOmatic didn't remove it from my lock file.

### Answer by username_0 on 2019-01-22. Score: 1

Solved:
removed "craftcms/vue-asset": "1.0.2"
and changed craftcms version number.
I also had to manually change a few required items as phpstorm seemed to be reverting their versions creating more problems

> **Comments:**
> **username_0**: Yes i had a few quirks with SEOmatic as i accidentally upgraded production db then synced it to local and ran into troubles. Probably the worst experience after a few years using craft so once a blue moon is not all bad. I think the blitz vendor folder is a good way to go in future.
