Typo in Triangles section of textbook

[nigel-f-wilson]

There is a paragraph that reads "You could also try using similar triangles, like we did in the previous course. This method requires knowing the distance to the base of the mountain: the point at sea level that directly below its summit." The final phrase should read "the point at sea level that lies directly below its summit."

I found the relevant content.md file and added in the missing word. I'll create a pull request based on that because I know the change I made won't have any unforeseen side effects. That said, I'd love to contribute more to Mathigon and I'm having a bit of trouble running the textbook program locally. After running npm install and then npm start I got the following error output. I'm wondering if I skipped a step on the setup or installation process?

Which version of Node do you have installed? You can check by using the command npm -v.

[nigel-f-wilson]

@polygonart6777 I'm running Node 16.13.1 and npm 8.13.1

Hi! Has this issue been resolved?

[Loren1999]

I had the same problem. node version: 16.18.1 npm version: 8.19.2 OS: Win10 64bit

我找到了相关的 content.md 文件并添加了缺少的单词。我将基于此创建一个拉取请求，因为我知道我所做的更改不会产生任何不可预见的副作用。也就是说，我很乐意为 Mathigon 做出更多贡献，但我在本地运行教科书程序时遇到了一些麻烦。运行npm install后，npm start我得到以下错误输出。我想知道我是否跳过了设置或安装过程中的一个步骤？

Mac上允许通过shebang传递CLI参数，但Linux不允许。 Linux系统需要将/node_modules/.bin/mgon-serve文件中第一行修改为#!/usr/bin/env ts-node-script

Windows系统下需要将/node_modules/.bin/mgon-serve.cmd进行如下改造 I hope it will help you.

[Loren1999]
