unable to perform npm installations in laravel vue project

问题

我正在为我的laravel vue项目执行npm install。但是npm install显示以下错误:

gyp verb find Python Python is not set from command line or npm configuration
gyp verb find Python Python is not set from environment variable PYTHON
gyp verb find Python checking if "python3" can be used
...

**注意:我之前使用yarn安装了一些东西,之后出现了这个问题。我以前没有用过yarn。我认为我搞砸了什么。**它总是显示python错误。为什么?

我卸载并重新安装了node.js,但错误没有消失。请帮忙。

Note: I installed something using yarn and after that this happened. I have not used yarn before. I think I messed up something.
Its always showing python errors. Why ?
I uninstalled and installed node.js freshly. But the error is not going . Help.

这意味着您要么没有在您的系统上安装Python 3.x,要么Python的安装二进制文件夹不在您的PATH中。Python的安装程序应该能够将其安装文件夹添加到您的PATH环境变量中。

如果您已经安装了Python,但仍然遇到此错误,请执行以下步骤:

  1. 右键单击开始菜单,转到系统
  2. 点击高级系统设置
  3. 点击环境变量
  4. 选择PATH并点击编辑...
  5. 点击新建并将Python的安装二进制文件夹添加到列表中。
英文:

It means that either you haven't installed Python 3.x on your system, or that Python's installation binary folder isn't in your PATH. Python's installer should be able to add its installation's folder to your PATH environment variable.

If you do have Python installed, and still encounter this error, then do the following steps:

  1. Right click on the start menu, go to System
  2. Click advanced system settings
  3. Click environment variables
  4. Select PATH and click on Edit...
  5. Click New and add Python's installation binary folder to the list.
