因此，当我在本地安装这些软件包时，它们可以工作，但是在全局安装时（并在本地删除它们）

 npm i babel-cli -g
 npm i -g babel-preset-es2015
 npm i -g babel-preset-es2015-node

似乎该标志没有设置 es2016-node 以查看全局包列表。无论如何都会发生以下错误：

npm run start myfile.js

babel-node --presets es2015-node -- bin/myScript.js "myfile.js"

/usr/local/Cellar/node/6.1.0/lib/node_modules/babel-cli/node_modules/babel-core/lib/transformation/file/options/option-manager.js:395
          throw new Error("Couldn't find preset " + (0, _stringify2.default)(val) + " relative to directory " + (0, _stringify2.default)(dirname));
          ^

错误消息中有提示：

找不到相对于目录“/Users/user/project/bin”的预设“es2015-node”

package.json在本地安装预设，并使用以下--save标志将它们保存为依赖项：

npm install --save babel-preset-es2015-node babel-preset-es2015

仅在本地查找预设是 Babel 的明智之举。通过这种方式，您被迫通过描述其package.json在npm install.
