我只能在全球范围内安装一个 npm 包

Question

这是我试图通过常规安装拉取一个包：

PS C:\temp> npm install aws-sam-local

> aws-sam-local@0.2.4 postinstall C:\temp\node_modules\aws-sam-local
> go-npm install

Downloading from URL: https://github.com/awslabs/aws-sam-local/releases/download/v0.2.4/sam_0.2.4_windows_amd64.tar.gz
fs.js:766
  return binding.rename(pathModule._makeLong(oldPath),
                 ^

Error: ENOENT: no such file or directory, rename 'C:\temp\node_modules\aws-sam-local\bin\sam.exe' -> 'C:\temp\node_modul
es\aws-sam-local\node_modules\.bin\sam.exe'

npm ERR!     C:\Users\meee\AppData\Roaming\npm-cache\_logs\2018-01-19T16_14_18_418Z-debug.log

与全局：

PS C:\temp> npm install --global aws-sam-local

> aws-sam-local@0.2.4 postinstall C:\Users\meee\AppData\Roaming\npm\node_modules\aws-sam-local
> go-npm install

Downloading from URL: https://github.com/awslabs/aws-sam-local/releases/download/v0.2.4/sam_0.2.4_windows_amd64.tar.gz
+ aws-sam-local@0.2.4
added 72 packages in 48.359s

为什么会损坏？如何将此包拉到所有用户都可以访问的特定文件夹？我想我的一些困惑是“全局”在这里甚至意味着什么，因为它仍然将它安装到我用户的文件夹中。

你没有package.json：no such file or directory, open 'C:\temp\package.json'

要在本地安装包，您需要在工作目录中使用 package.json 来跟踪本地依赖项。您可以使用npm init 创建一个package.json。

阅读here 了解全局和本地包：

globally - 这会在 {prefix}/lib/node_modules 中删除模块，并将 {prefix}/bin 中的可执行文件，其中{prefix} 通常是一些东西 喜欢/usr/local。它还会在{prefix}/share/man 中安装手册页，如果 他们提供。

本地 - 这会将您的软件包安装在当前 工作目录。节点模块进入./node_modules，可执行文件进入 在./node_modules/.bin/ 中，根本没有安装手册页。

编辑：

• 使用npm list -g --depth=0 列出所有全局包
• aws-sam-local 应该使用npm install -g aws-sam-local 全局安装
• Global npm install location on windows? 和 Folder Structures Used by npm
