node.js - 如何使 bin 脚本可用于本地安装的 npm 包

Question

我在 npm 文档中读到，您不能使用本地安装的软件包的 bin 脚本。

那么，本地安装时如何以 bin 命令启动 gulp 呢？是什么使它在本地安装时可用，我查看了 gulp package.json 和 bin 脚本，但没有找到任何答案。

From NPMJS documentation:

To use this, supply a bin field in your package.json which is a map of command name to local file name. On install, npm will symlink that file into prefix/bin for global installs, or ./node_modules/.bin/ for local installs.

因此，您本地安装的软件包二进制文件将像这样可执行

./bin/node_modules/.bin/the_binary

如果您想直接启动二进制文件，则可以使用此选项。或者，如 the scripts part of the documentation: 中指定的那样

In addition to the shell's pre-existing PATH, npm run adds node_modules/.bin to the PATH provided to scripts.

因此，您可以简单地编写一个包装脚本，例如

scripts: {
  "build": "the_binary"
}

并像这样调用你的脚本

npm run build

As of npm@2.0.0, you can use custom arguments when executing scripts. The special option -- is used by getopt to delimit the end of the options. npm will pass all the arguments after the -- directly to your script:

npm run test -- --grep="pattern"
