node.js & react - 服务器未启动，来自 github 项目

Question

我在 GitHub darkwire 上找到了一个项目，想安装并使用它。首先，我尝试从 windows 安装它。我安装了 Node.js 和 Yarn，我在使用命令时遇到错误：yarn dev

`C:\darkwire.io-master>yarn dev
yarn run v1.21.1
$ concurrently 'cd client && yarn start' 'cd server && yarn dev'
[0] 'c' is not recognized as an internal or external command,
[0] operable program or batch file.
[1] 'client' is not recognized as an internal or external command,

[0] c exited with code 1
[1] client exited with code 1
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.`

我的下一步是在 ubuntu 19.10 中尝试，首先我再次安装 Node.js 和 Yarn，然后再次使用：yarn dev。我得到一个错误，但现在是开放的网站，它不工作，只是说 "Disconnected"

```qq@ubuntu:~/Downloads/darkwire.io-master$ yarn dev
yarn run v1.21.1
$ concurrently 'cd client && yarn start' 'cd server && yarn dev'
$ nodemon src/index.js --exec babel-node

我想我的版本可能不对 Node.js 并尝试安装 9.x 版本，重新下载项目并重试，它没有帮助，尝试将端口从 3001 更改为 3000，没有帮助。
