npm安装错误-跳过可选功能

Question

我正在尝试与laragon一起学习laravel在线课程。我需要运行命令npm install，但这标志着一个错误，我不知道如何解决。

我试图修改路径，但这没用

C:\laragon\www\social>npm install
"CALL "C:\laragon\nodejs\\node.exe" "C:\laragon\nodejs\\node_modules\npm\bin\npm-cli.js" prefix -g" no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

> node-sass@4.11.0 install C:\laragon\www\social\node_modules\node-sass
> node scripts/install.js

我希望此命令能够正常运行，但会标记这些错误，请帮帮我

P.S：我正在使用Windows 7家庭高级版的笔记本电脑。

Answer 1

1. $ npm cache clean --force
2. 通过$ rm -rf node_modules
删除node_modules
3. $ npm install

然后使用$ npm start

重新开始

Answer 2

我认为您应该手动安装ajv软件包或将其更新为6.0版（如果您已经具有较低版本）

command.ExecuteReader

我有类似的问题。更新后，它可以正常工作。尝试对其他错误也这样做。
