运行报错 Error: Cannot find module '@lerna/add/command'

是按照老师的方法，我看很多同学都有这种问题，但是都没有解决，不知道是老师 lerna 源码和我们不一直导致的吗？（最新的 code 外层 package 没有 bin）

删除重新安装什么都试过了就是不行，就是没手动一个个从远程仓库安装他们下来

IDE 爆红就是这些 

const addCmd = require("@lerna/add/command");
const bootstrapCmd = require("@lerna/bootstrap/command");
const changedCmd = require("@lerna/changed/command");
const cleanCmd = require("@lerna/clean/command");
const createCmd = require("@lerna/create/command");
const diffCmd = require("@lerna/diff/command");
const execCmd = require("@lerna/exec/command");
const importCmd = require("@lerna/import/command");
const infoCmd = require("@lerna/info/command");
const initCmd = require("@lerna/init/command");
const linkCmd = require("@lerna/link/command");
const listCmd = require("@lerna/list/command");
const publishCmd = require("@lerna/publish/command");
const runCmd = require("@lerna/run/command");
const versionCmd = require("@lerna/version/command");

​就是这些 local dependency

"@lerna/add": "file:../../commands/add",
"@lerna/bootstrap": "file:../../commands/bootstrap",
"@lerna/changed": "file:../../commands/changed",
"@lerna/clean": "file:../../commands/clean",

弄了我几个小时，请老师指点
