I am deploying to netlify and I keep running into this error 

My master branch deploys with no errors but my developer branch keeps having the same issue. Here is a picture of my log where it is failing. I can also npm run build locally and there are no errors.

正如您在评论中提到的，问题是Netlify的npm版本要高得多，超过了您的本地环境，因此您的代码某些语法已被弃用，不再被（更新的）npm理解。
建议升级您的本地npm版本，但如果现在不可能，您可以降级Netlify的npm版本。
为了设置Netlify的npm版本，您可以使用`NODE_VERSION`环境变量。
前往`https://app.netlify.com/sites/<site-name>/settings/env#environment-variables`，添加`NODE_VERSION`变量，并将其设置为您的本地npm版本。

As you mentioned in your comment, the issue is Netlify&#39;s npm version is much higher than your local environment and thus some syntax of your code is deprecated and no longer understood by the (newer) npm.
It is recommended to upgrade your local npm version, but if it&#39;s not possible right now, you can downgrade Netlify&#39;s npm version.
In order to set Netlify&#39;s npm version, you can use `NODE_VERSION` environment variable.
Go to `https://app.netlify.com/sites/&lt;site-name&gt;/settings/env#environment-variables` and add `NODE_VERSION` variable and set it as your local npm version.
