尝试链接本地 npm 模块时出现 E404

Question

尝试npm按照文档链接本地模块时出现 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

我试图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 安装的 Node.js 版本来运行npm link my-module-name，但您没有npm link使用相同版本运行（在模块的目录中）。

初始链接是在 中创建的/usr/local/lib/node_modules，但是当您使用 NVM 时，每个 Node.js 版本都会获得自己的“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。
