Hi�,

your console log isn't readable�����

Also, we don't support Windows systems as we don't develop on it.

But hey I was just trying to be nice and let you know this is a problem. If you look at line 109 in the 1st post, I took the time to highlight it for you, it should not matter if its windows or other OS. Its an NPM dependency package issue.

Then of course there is 111 error Could not resolve dependency: or maybe 111 error Fix the upstream dependency conflict,

��� ����� of course.

As of this post Feb 17, 2021... you still have a dependency package issue. If someone is nice enough to take time to post a log file to show you a bug, maybe read it?

Tested on Linux: no problem

➜  npm -v
6.14.4
➜  node -v
v12.16.1
➜  npm install react-admin
[...]
+ react-admin@3.12.4
added 153 packages from 186 contributors and audited 153 packages in 49.267s

So either it's a problem with your npm cache, or with a more recent version of node/npm, or with Windows.

[fzaninotto]

This is caused by npm 7.x, which broke BC by installing peer dependences (https://github.blog/2020-10-13-presenting-v7-0-0-of-the-npm-cli/). The connected-react-router package must be modified to allow react 17 as peer dependency.

As this is an external package, we can't really solve this problem in react-admin.

In the meantime, we recommend that you use yarn or downgrade to npm 6.

Fixed by connected-react-router v6.9.1.

Fixed by connected-react-router v6.9.1.

Wait, @fzaninotto apologies, what do you mean fixed "by connected-react-router"? How can I resolve this?

npm Installing connected-react-router v6.9.1 doesn't do anything to resolve the issue, so I assume I'm misinterpreting.

EDIT: Got it. npm update -> Then install again.
