我不确定为什么我的软件包无法安装。我有一段模糊的回忆，我有一段时间更新了npm url，但是这里的URL看起来还可以。有什么建议吗？

Answer 1

您是否正在代理或防火墙后面访问Internet？许多大型企业都有阻止这些来源的防火墙。如果不是这种情况，则可能是您所在地区的npm来源很慢或被阻止。尝试在本地搜索Google NPM源。

在中国，“ https://npm.taobao.org”比官方npm注册要快得多。

抱歉，我没有足够的声誉来发表评论。

Answer 2

转到其底部。我已经删除了应用程序文件夹的内容，并将一组新的程序文件复制到其中。我没有注意到的是，当我执行删除操作时，终端遵循删除文件的路径，因此实际上是指向垃圾桶中的某个位置，该位置似乎引起了npm install的问题。

更改到正确的目录并运行npm install再次解决了该问题。

npm install返回304和404错误，而不是安装软件包
