Hi, I see you have closed this issue... So I think you have already fixed this problem.😂 And that would be great if you could share about how you fixed it incase anybody had the same problem. Thanks!

[umarhadi]

I give up haha. 😂 I’m closed this issue because, when I deployed with default version dependecies on package.json, It works with no problems. But, I cannot run yarn dev on my local computer. Hope you can help me with upgrade version dependecies haha, Thanks

[CharlesFeng47]

Actually, I cannot run yarn dev on my local computer right now as well... However, I remember I could when I started this project and I just could not make it someday suddenly, but it still works fine on Netlify/Travis, so I thought there might be some dependencies conflict with other projects because I need to handle another project at that time by coincidence. At last, I just let it go because it's not emergent and everything goes well on the deployment.

Anyway, the problem is not only on my own local computer and I would try to fix it if I had time. 😃

[umarhadi]

Yassss, Thank you. Hope you had more time, have a nice day!😁

Hi there! I tried to solve the compile errors on my own local computer and these errors are related to my macOS version Catalina and Homebrew, so I solved mine and found it do not make sense to your case. 😂 Anyway, you made me to solve it, Thanks!!!

Then I checked your error logs and think this on StackOverflow would be helpful. Try it! 😛
