Question

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，这些解决方案并没有多大帮助。

1. sudo npm clear cache 
2. sudo npm update -g
3. Permission fix: by changing nodejs folder's permission to local user

（参阅：npm install errors with Error: ENOENT, chmod）

我想知道造成这个问题的原因。由于我没有发布我自己的应用程序，因此无法根据链接中提供的解决方案包含.npmignore。该链接中的第二个答案声称问题的性质是：

“上面的操作导致一些依赖项被安装在〜/ .npm / dir中，拥有root：root所有权（因为sudo ...）。显然npm不会以本地用户身份运行（或者之后更改依赖关系子目录所有权）拉动依赖关系并将它们写入本地用户子目〜/ .npm /。只要npm对基本的unix文件系统安全问题如此粗心，问题就会再次发生。“

我怀疑这是否正确。安装MEANIO不应该造成太多问题。

shell命令和错误消息如下所示：

localhost:local Nick_Guan$ sudo npm install -g meanio@latest

任何帮助都将不胜感激。

Answer 1

仔细检查是否正确安装了先决条件，确保在主目录下的某个位置执行install命令。

您位于可以阅读的目录中仅由root搜索，并且您已经转到其他用户。那个用户没有权限搜索当前目录，甚至找不到 `..＆＃39;，所以getcwd会失败。

Answer 2

我遇到了类似的问题，发现权限问题出现在我的root用户目录/User/tomk/.npm的基本npm目录中。 npm的子目录由root拥有（可能来自sudo以安装node / npm）。一旦我将所有权更改为我的帐户，就安装了meanio而没有致命错误（许多警告，但没有什么可以阻止安装）。
