Why can't I access the "https://github.com/ricmoo/ens-normalize.js.git" resource successfully when running "yarn add ethers"?

[Dear-MrHe]

When I run "yarn add ethers", I always get stuck on accessing the "https://github.com/ricmoo/ens-normalize.js.git" resource, and finally the following error occurs.

yarn add v1.22.15

Can someone help me?

@Dear-MrHe Not sure about this error. Try with npm and see.

[Dear-MrHe]

@alymurtazamemon Ok, I'll push the code to GitHub later and post the link later, thanks.

[Dear-MrHe]

@Dear-MrHe I will fork your repo, look into issues and push the fixed code on your repository again. I need to see which things are not allowing ethers to install in your project.

@alymurtazamemon Hello, I have the following problem when pushing the code to my GitHub repository:

@Dear-MrHe
try this
In your terminal

git config http.postBuffer 524288000

then try pushing again

[Dear-MrHe]

@aaankeet Still not working, same error.

@Dear-MrHe

I think you are not able to establish a secure connection with github there might be a problem with your wsl server
try updating your wsl.

Well, I found out that I added the SSH public key to my account and I was able to push to the repository, but why? I use https. Then I can download ethers with npm, but it still doesn't work with yarn, still the same error.

[Dear-MrHe]

Oh, yes, I finally found out that it was actually a network problem. This problem occurred on the company's network.

[aaankeet]

yea that makes sense corporate networks are sometimes restricted

[aaankeet]

mind if you mark this answered?

[Dear-MrHe]

Ok, and when I downloaded ethers with npm install --save ethers, it was actually the v6 version, and the following error occurred when I used const provider = new ethers.providers.JsonRpcProvider() to establish a connection with the blockchain.

TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

After searching on Google, I found that it was a version problem, and the version of ethers needed to be lowered, so I used the command yarn add [email protected] to download ethers correctly.
