I am also seeing this error. I've been pulling my hair out trying to resolve. I've reinstalled the CLI components several times and have started with a clean .sfdx directory. Currently am completely blocked on development.

My scenario:

PS C:\git\repos\salesforce-adapter> sfdx force:auth:web:login -d -a [myHub]
ERROR running force:auth:web:login:  Cannot read property 'getInstance' of undefined

The log files show:

{"name":"sfdx","hostname":"GAINE-DEV16","pid":21772,"log":"SfdxProjectJson","level":40,"msg":"The config file: C:\\Users\\Chris Williams\\.sfdx\\sfdx-project.json is not schema valid\nDue to: Validation errors:\nshould have required property 'packageDirectories'","time":"2020-08-13T17:20:12.781Z","v":0}

I do not have a sfdx-project.json file in my .sfdx directory.

The only file in .sfdx is sfdx.log.

I do have a sfdx-project.json file in my current project directory. It has the correct packageDirectories content.

Facing same issue while pushing any lwc component to org.

@chriswill @dhaniksahni @quygiengtmobile I'm wondering if this is a new issue or a previously existing one, have you tried downgrading to a previous CLI version ?

This is due to having unnecessary plugins installed. We still aren't sure why the node_module resolution is getting messed up because the getInstance is there until it goes into the overwritten plugin code.

You should be able to do sfdx plugins to see what you have installed and do sfdx plugins:uninstall salesforcedx or whatever the offending plugins is.

See #555 for more details.

Notice in the thread you should not reinstall those plugins unless targeting old plugin versions.

Thank you! I've been searching for a solution for this for several days now.

Just some background to assist others: I'm not sure what triggered the Cannot read property 'getInstance' of undefined error initially, but one day it was working, the next day it wasn't. I did not upgrade the CLI, it has been running version 7.69.0-c7be45ae22 for several weeks now. I checked for an update today, which updated it to sfdx-cli/7.70.1-3d8a6229fc. The update didn't help, but after finding this post I did the following to resolve the issue:
sfdx plugins:uninstall salesforcedx

@amphro Are you saying there is no need to reinstall the salesforcedx plugin? Are they part of the sfdx core package now?

Hi All,
I fixed this issue by clear all cli cache and data then install again.

[chriswill]

I fixed this issue by following steps in #555

sfdx plugins:uninstall salesforcedx

Make sure your .sfdx folder has a sfdx-config.json file. If it is present try removing it and adding it again and authorize an org. the file should contain a json structure as follows:
{
"defaultusername": "org alias name"
}
Authorize an org again and you should be good.

I tried the same and it redirected me to salesforce log in page and now the error does not come anymore.

| @amphro Are you saying there is no need to reinstall the salesforcedx plugin? Are they part of the sfdx core package now?

Correct. They have been bundled with the CLI since the beginning. You only need to install it if you want to hardcode to a specific version.

Closing this.
