I got this error for the a long while. Stupidly I hadn't installed gulp... In short this problem occurs when a package is missing.
很长一段时间我都遇到了这个错误。愚蠢的是我没有安装 gulp ......简而言之，当一个包丢失时会出现这个问题。
npm install gulp -g
I would suggest working out which task you are running and then install that.
我建议找出您正在运行的任务，然后安装它。

In my case, (windows) after uninstalling nodejs, and before reinstalling it I had to delete the folder:
在我的情况下，（windows）卸载 nodejs 后，在重新安装它之前，我必须删除该文件夹：
C:\Program Files\nodejs\node_modules\npm
C:\Program Files\nodejs\node_modules\npm
and after reinstalling node it worked like a sharm
重新安装节点后，它就像一个 sharm

There were many reason for this issue: I have faced this issue because I had older version of node.js related files.
这个问题有很多原因：我遇到这个问题是因为我有旧版本的 node.js 相关文件。
- Un-install the node.js
- Go to your user folder like
C:\Users\<uname>and find all the node.js related files and delete everything. - Install node.js freshly
- 卸载 node.js
- 转到您的用户文件夹
C:\Users\<uname>，找到所有与 node.js 相关的文件并删除所有内容。 - 全新安装 node.js
It worked for me.
它对我有用。

After grepping I found:
grepping后我发现：
$ cd /usr/lib/
$ ack-grep readable-stream
nodejs/sha/index.js
3:var Transform = require('stream').Transform || require('readable-stream').Transform
and change that line to:
并将该行更改为：
var Transform = require('stream').Transform // || require('readable-stream').Transform
and error goes out!
错误消失了！
