Do not use echo command on win10, create the mardown file directly.

Would you please provide us with the source markdown file?

ulivz on 15 Apr 2018

The source markdwon file is created by echo "# Hello VuePress" > README.md on Win10 Powershell

LinFeng1997 on 15 Apr 2018

Can you provide the node version?

ulivz on 15 Apr 2018

8.9.3

LinFeng1997 on 15 Apr 2018

removing double quotes work!

cosimochellini on 15 Apr 2018

I was having this problem too, and there were never any double quotes in the README.md file. Like the OP I created the file using Windows Power Shell and the echo command provided at https://vuepress.vuejs.org/guide/getting-started.html What I did to get things to work is not rely on the echo command, and instead create the file directly inside Visual Studio Code, and copy/paste (or type) # Hello VuePress!" into it.
