node.js - 在执行 'npm install brain.js' 时如何解决这个奇怪的错误？

Question

我的目标是在nodejs中测试brain.js脚本，但我不能。我执行了这个命令:

npm install Brain.js

我得到了这个结果:

C:\Users\alumno_ciclo\Desktop\papelera>npm install brain.js

我尝试重新安装nodejs，安装python，并配置一些窗口的变量。但事实并非如此，这个命令是不可能运行的。有人可以帮助我吗？不管怎样，谢谢。

首先在 CMD 上以管理员模式运行“npm install --global windows-build-tools”，然后再次运行“npm install Brain.js”。

最好，
