Can't upgrade v2 from alpha.55 -> alpha.61 -Can't resolve 'docsearch.js'

🐛 Bug Report

Thank you for docusaurus and Version 2 is already incredible.

I am trying to upgrade from alpha.55 to version alpha.61. I can’t tell what I am doing wrong but I am getting an error

Failed to compile
./src/theme/SearchBar/index.js
Module not found: Can't resolve 'docsearch.js' in '/Users/david/repos/erxes/docs/src/theme/SearchBar'

Have you read the Contributing Guidelines on issues?

Yes, I have read this.

To Reproduce

1. In my package.json, under the dependences, change from version alpha.55, to version alpha.61

   "@docusaurus/core": "^2.0.0-alpha.61",
    "@docusaurus/preset-classic": "^2.0.0-alpha.61",

1. In the terminal, in the directory for “/docs”, run yarn install to install upgraded version
2. Then run yarn start

Expected behavior

I expected to have my installation work in the browser, and to be able to continue developing my app.

Actual Behavior

Something went wrong:

1. I got a bunch of warnings- but I don’t think this is the cause.

2. I ran yarn start. I got an error ValidationError: "homePageId" is not allowed to be empty

So, in the docusaurus.config.js, I commented out homepageId <-- which was in empty quotes. (I have no idea what to put in there, I tried ‘docs/’. Either way I am able to continue with the installation. I tried with and without docs/ (See below)

1. I ran yarn start again. I got a reasonable error message, ValidationError: themeConfig.navbar.links has been renamed as themeConfig.navbar.items

So, in the docusaurus.config.js, I changed themeConfig.navbar.links to themeConfig.navbar.items.

1. I ran yarn start again. I got an error ValidationError: "navbar.items[0].activeBasePath" is not allowed to be empty

I had two .items with activeBasePath, both were empty string quotes, and I commented both of them out.

1. I ran yarn start again. This time it seemed to run, but I got the following errors, in my terminal:

The same error in my browser,

Failed to compile
./src/theme/SearchBar/index.js
Module not found: Can't resolve 'docsearch.js' in '/Users/david/repos/erxes/docs/src/theme/SearchBar' 

Note:

• Everything was working great before the upgrade, but I wanted to upgrade
• I have done the above steps 5 times with exactly the same results
• I searched the docs, github and google and cannot find any reference to this issue. I suspect this is something I am doing wrong, and not necessarily a docusaurus issue.

Your Environment

• Docusaurus version used: upgrading from version 2 alpha.55 to alpha.61
• Environment name and version (e.g. Chrome 78.0.3904.108, Node.js 10.17.0): on a Mac with latest Node

Thank you.

@davidkartuzinski New release contains an update to algolia search plugin and due to your website swizzles searchBar it is broken.

@anshulrgoyal - No problem about the errors! They makes sense. I understand this is alpha, and it is already so polished with in terminal messages and instructions! So great. I consider this issue my ignorance, not anything “wrong” with docusaurus.

Your instructions helped me to understand what was happening. What I did to fix this issue was to go into the node_modules/@docusaurus/ and delete the @docusaurus/theme-search-algolia, then at the terminal I just simply ran yarn add @docusaurus/theme-search-algolia and everything now works.

Again thank you for your incredibly fast response. This issue is resolved for me.

I wanted to add that simply removing it didn’t fix the issue. Also simply just installing it didn’t work either. I had to delete it from the. node_modules, and then reinstall it.
