我已经查看了大约 20 多个与在 Windows 上安装 npm 模块和获取 node-pre-gyp 或 libxmls 错误有关的问题。大多数问题都超过一年了，所以我想我会在 2019 年 6 月问这个问题，以防人们仍然有问题！

这个特定的错误发生在模块excel-as-json上。

  1. 节点版本 - 8.11.0
  2. npm 版本 - 5.6.0
  3. 视窗 10
  4. 我在企业防火墙后面，我设置了

npm config set http-proxy,npm config set https-proxy npm config set registry `http://registry.npmjs.org/

  1. 我已经安装了 windows-build-tools（虽然它似乎只安装在管理员用户中，但我将安装的内容复制并粘贴到非管理员用户中）。
  2. 当我尝试运行它时，有时会出现错误npm install -g excel-as-json --proxy http://proxy.host.com:8080

吉普错误！堆栈错误：找不到 Python 可执行文件“C:\Users\User\AppData\Local\Programs\Python27”，您可以设置 PYTHON 环境变量。吉普错误！堆栈在 PythonFinder.failNoPython (C:\Users\User\AppData\Roaming\nvm\v8.11.0\node_modules\npm\node_modules\node-gyp\lib\configure.js:483:19) gyp ERR！PythonFinder 的堆栈。(C:\Users\User\AppData\Roaming\nvm\v8.11.0\node_modules\npm\node_modules\node-gyp\lib\configure.js:508:16) gyp 错误！堆栈在 C:\Users\User\AppData\Roaming\nvm\v8.11.0\node_modules\npm\node_modules\graceful-fs\polyfills.js:284:29 gyp 错误！堆栈在 FSReqWrap.oncomplete (fs.js:152:21)

请帮忙！我花了大约 14 个小时试图解决这个问题，但我不知道。

我遇到了同样的问题，这个答案为我解决了这个问题：https ://stackoverflow.com/a/30341389/10691936

#For Windows/MacOS/Linux
npm config set cafile "<path to your certificate file>"

#Check the 'cafile'
npm config get cafile

我也让 ssl 功能处于活动状态

npm config set strict-ssl true
npm config set registry https://registry.npmjs.org/ --global

而“node-pre-gyp”实际上使用了与 npm 不同的代理设置，它是在环境变量中设置的，所以在 Windows 下我这样做了：

set https_proxy=<your proxy>
set http_proxy=<your proxy>
