Question

我正在Windows 10中从git-bash-cli运行“ npm install node-sass”，并且无法将“节点”识别为内部或外部命令，可操作的程序或批处理文件。”错误。

多年以来，我一直在使用此设置，当我将节点升级到10.16.0时，问题开始了。

为避免不必要的答复：

我看到的所有问题都只是添加路径变量。

我已经将Node添加到PATH变量中，并尝试了多种不同的编写方式。我最终重新安装了Node.js，它会自动执行，因此就这样了。

节点从命令行运行，而不是从脚本运行，例如package.json文件中的脚本。

我尝试重新安装节点8.11.3，这是问题开始之前我所使用的版本，但出现相同的错误。我又回到了10.16.0版。

错误代码如下：


> node-sass@4.12.0 install C:\projects\true\true\website\truevue\node_modules\node-sass
> node scripts/install.js

'node' is not recognized as an internal or external command,

Answer 1

最后找到了答案。我最终所做的只是运行npm update -g，它解决了该问题

感谢所有帮助过的人，希望这可以帮助其他人

Answer 2

我认为您必须将node.js的路径添加到系统变量

首先：打开控制面板->系统和安全->系统->高级系统设置->环境变量

第二个：在“用户变量”或“系统变量”中找到变量PATH并添加node.js文件夹路径作为值。它是C：\ Program Files \ nodejs；如果不存在，则创建它。

第三：重新启动计算机。
