最近我的电脑无法运行 npm install。
我知道这个问题已经被问过了，无论如何我已经检查了许多类似的问题，但仍然没有帮助。因此，我在以下代码下添加了更多信息。
先说问题。
$ npm install -dd
npm info it worked if it ends with ok

我周围的所有人（在同一个办公室、网络、代理等）都没有这个问题，而且我的计算机之前能够运行该命令。看来这不是连接问题，因为我在这里（检查 NodeJs 中的互联网连接）以下函数来检查是否可以解析 URL，并得到答案“已连接”
require('dns').resolve('www.wikipedia.com', function(err) {
if (err) {
console.log("No connection");
} else {
console.log("Connected");
}
});
> Connected
即使我清理了缓存，您也可以看到每个 url 都是从缓存中获取的：
C:\Program Files\nodejs我在运行的命令行中手动删除了缓存npm cache clean --force。这个缓存还能在哪里？- 我没有任何
package-lock.json文件，无论如何我删除了node_modules项目中的文件夹。 - 正如您在错误日志中看到的那样，我卸载并重新安装了最新的 nodejs。
有什么提示吗？
