当我尝试使用 npm 在我的 Mac 上安装 MEANIO 时，我遇到了几个安装失败的错误。错误如下所示：
有两种主要类型的问题：一种是Error EACCES，另一种是ERROR ENOENT。我尝试了几种解决方案，但并没有太大帮助。
1. sudo npm clear cache
2. sudo npm update -g
3. Permission fix: by changing nodejs folder's permission to local user
（请参阅：npm install 错误错误：ENOENT, chmod）
我想知道是什么导致了这个问题。由于我没有发布自己的应用程序，因此无法根据链接中提供的解决方案包含 .npmignore。链接中的第二个答案声称问题的性质是：
“上述操作导致在 ~/.npm/ 目录中安装了一些依赖项，具有 root:root 所有权（因为 sudo ...）。显然，在拉取依赖项和将它们写入本地用户子目录 ~/.npm/。只要 npm 对基本的 unix 文件系统安全问题如此粗心，问题就会再次出现。”
我怀疑这在我的情况下是否正确。MEANIO 的安装不应该引起这么多问题。
shell 命令和错误信息如下所示：
