node.js - 尝试链接本地 npm 模块时出现 E404

Question

在 docs 之后尝试将本地模块与 npm 链接时出现 404 错误

在本地模块目录中，它似乎正确地创建了一个全局链接:

$ npm link
/usr/local/lib/node_modules/my-module-name -> /Users/XXX/my-module-directory/my-module-name

但是在那之后我尝试从其他项目目录链接它时我收到 404 错误:

$ npm link my-module-name
npm ERR! code E404
npm ERR! 404 Not Found: my-module-name@latest

我尝试取消链接模块并再次链接或更改版本，但它不起作用。

这是完整的日志:

您正在使用 NVM 安装版本的 Node.js 来运行 npm link my-module-name，但您没有运行 npm link(在你模块的目录)使用相同的版本。

初始链接是在 /usr/local/lib/node_modules 中创建的，但是当您使用 NVM 时，每个 Node.js 版本都有自己的“lib”目录，在您的示例中 /Users/XXX/.nvm/versions/node/v8.2.1/lib/node_modules，这是一个不同的目录。
