更新：经过测试，这似乎扩展到了node_modules / .bin中的任何软件包。本地bin出现在npm错误日志中，但似乎找不到或执行任何本地安装的软件包。将类似./node_modules/.bin或$（npm bin）的内容添加到PATH确实可以，但这似乎不需要解决。
我尝试按照next.js的非常基本的设置进行操作，但是不成功。我很想在全球范围内安装下一个，但是基于我在他们的Github上看到的问题，这不是必须的。我环顾了Google和SO，但找不到任何帮助我的东西。
我一直执行setup的第一步，一直运行npm run dev。该命令失败，提示sh: next: command not found
这是npm错误的日志。在我看来，该项目的node_modules / .bin的路径位于npm run所查找的路径中。我查看了该文件夹，接下来是该文件夹。真的不确定我应该从那里去哪里。
