如何构建/安装可以全局使用的node-command-line-tool?

我写了一个名为" extractdeps"的小命令行实用程序,它将列出来自package.json文件的节点应用程序的所有依赖项。

与其他节点实用程序不同,例如" jest"我无法在没有进入其具体路径的情况下在shell中全局执行它。

安装示例:

$ npm install --verbose -g extractdeps -g
npm info it worked if it ends with ok
npm verb cli [ '/usr/local/Cellar/node/8.9.1/bin/node',
npm verb cli   '/usr/local/bin/npm',
npm verb cli   'install',
npm verb cli   '--verbose',
npm verb cli   '-g',
npm verb cli   'extractdeps',
npm verb cli   '-g' ]
npm info using npm@5.5.1
npm info using node@v8.9.1

npm verb exit [ 0, true ]
npm info ok

但执行失败:

$ extractdeps
-bash: extractdeps: command not found

如果我使用 jest 等其他工具执行相同操作,则效果非常好:

$ jest
-bash: jest: command not found

$ npm install -g jest
/usr/local/bin/jest -> /usr/local/lib/node_modules/jest/bin/jest.js

$ jest -v
No tests found

我错过了什么?

所以,我刚刚在全球安装了这个包,并注意到了同样的交易。我想知道您是否需要在"bin"中指定package.json标记。看起来它正在安装模块,但它不知道要添加到/usr/local/bin的内容。

例如,在grunt-cli package.json:

"bin": {
    "grunt": "bin/grunt"
 },

更新:做了一些研究,确实看起来是个问题。 https://docs.npmjs.com/files/package.json#bin

基本上,当您指定此标志并执行全局安装时,npm会在您指定的任何cli入口点的本地bin中创建一个符号链接。
