npm WARN deprecated har-validator@5.1.3: this library is no longer supported
npm WARN deprecated debug@4.1.1: Debug versions >=3.2.0 <3.2.7 || >=4 <4.3.1 have a low-severity ReDos regression when used in a Node.js environment. It is recommended you upgrade to 3.2.7 or 4.3.1. (https://github.com/visionmedia/debug/issues/797)
npm WARN deprecated debug@3.2.6: Debug versions >=3.2.0 <3.2.7 || >=4 <4.3.1 have a low-severity ReDos regression when used in a Node.js environment. It is recommended you upgrade to 3.2.7 or 4.3.1. (https://github.com/visionmedia/debug/issues/797)
npm WARN deprecated @babel/polyfill@7.4.4:  This package has been deprecated in favor of separate inclusion of a polyfill and regenerator-runtime (when needed). See the @babel/polyfill docs (https://babeljs.io/docs/en/babel-polyfill) for more information.
npm WARN deprecated uuid@3.3.3: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
npm WARN deprecated request@2.88.0: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated mkdirp@0.5.1: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)
npm WARN deprecated ecstatic@3.3.2: This package is unmaintained and deprecated. See the GH Issue 259.
npm WARN deprecated tar@2.2.2: This version of tar is no longer supported, and will not receive security updates. Please upgrade asap.
npm WARN deprecated core-js@2.6.9: core-js@<3.4 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. 
Please, upgrade your dependencies to the actual version of core-js.

Gyp需要Python，而当您在Windows上时。

• 安装Python并确保将其包含在您的路径中。
• 尝试使用--没有可选的标志运行npm安装。
• 尝试下载windows-build-tools包.
