yarn can not get integrity value

It's a bug.

E:\React1>yarn
yarn install v1.12.1
[1/4] Resolving packages...
[2/4] Fetching packages...
error https://outlookweb.pkgs.visualstudio.com/_packaging/owa-npm/npm/registry/@microsoft/load-themed-styles/-/load-themed-styles-1.7.73.tgz: Integrity check failed for "@microsoft/load-themed-styles" (computed integrity doesn't match our records, got "sha1-2jmj7l5rSw0yVb/vlWAYkK/YBwk=")

Yarn failed to get the integrity value from network package.

How can I get the above issue fixed?
Even after I manually clear yarn cache folder, the following cmd also fails.
E:\React1>yarn cache clean
yarn cache v1.12.1

One important note: "sha1-2jmj7l5rSw0yVb/vlWAYkK/YBwk=" is the result you get when hashing null

[rally25rs]

@imsnif is this related to the integrity work that you did a few months back?

[imsnif]

The error is. I think what's happening here is that we're trying to calculate the integrity of null (as @MLoughry mentioned) and comparing it to our local integrity of, well... not null. :)
I don't know about the yarn cache clean error, but I'd imagine this would be fixed as soon as network connectivity comes back, wouldn't it? The heap issue is alarming, but I don't think it's related.

when it happens, my network seems totally fine.
