运行我的项目包时，我遇到了上述标题错误，之后我尝试使用以下命令安装该软件包：npm install xml2json。但是，我只收到了以下错误，请给我建议或想法以解决这个问题...

预先感谢，Gopal R

运行以下命令进行安装：npm install xml2json --save - Mohammad Raheem
没有@MohammadRaheem，仅加--save参数依然会出现相同的错误，这只是在package.json文件中保存名称而已。 - R.G.Krish
你正在使用 Angular 2/4 吗？ - Darshan Vachhani
不是 @D.V，这是一种中间件应用程序。 - R.G.Krish
删除 node modules 目录，使用 npm cache clean --force 命令清除 npm-cache，然后尝试通过运行 npm install xml2json --unsafe-perm 命令安装相同的包，如果在相同的依赖项处中断，则使用 npm install node-expat@2.3.16 --unsafe-perm 命令。 - Suhas Gavad

我已经解决了这个问题
使用下面的命令：npm install xml2json-light
并把let parser = require('xml2json');修改为let parser = require('xml2json-light');
这对我有用

我已经解决了这个问题。如果你注意到命令的这一部分 else (node "" rebuild )，我认为发生的是它错误地将 if not defined npm_config_node_gyp 评估为 false，并尝试运行空值而不是 node-gyp。你需要做的是定义你的 npm_config_node_gyp 变量。你可以这样做： export npm_config_node_gyp=<PATH_TO_NODE_GYP_PACKAGE_FOLDER> 记住，在 Windows 中需要双反斜杠。对于我来说，看起来像这样： export npm_config_node_gyp=C:\\Users\\781990\\AppData\\Roaming\\nvm\\v6.11.0\\node_modules\\node-gyp

编辑： 修复后还有一个步骤。在执行代码时，缺少 expat 绑定。要解决此问题，请将 bin 文件夹和 node-gyp 可执行文件添加到 npm_config_node_gyp 变量中，并在 node_modules\node-expat 文件夹中运行 node-gyp rebuild。例如： export npm_config_node_gyp=C:\\Users\\781990\\AppData\\Roaming\\nvm\\v6.11.0\\node_modules\\node-gyp\\bin\\node-gyp.js cd node_modules\node-expat node-gyp rebuild
