# Bug缘由   Bug birth crib

偶然兴起学学微前端的课程，建一个git repo然后 pnpx create-mf-app

I got pregnant in the head so I started learning micro frontend. I created a git repo then execute some funny code.

yarn是几万年前装的。

I installed yarn before my first yarn.

今不巧，当即给我尥蹶子报了个奇怪的错

Dang, yarn showed me how tough she can be today

yarn install v1.22.19
info No lockfile found.
[1/4] Resolving packages...
warning webpack-dev-server > webpack-dev-middleware > memfs@3.6.0: this will be v4

随便翻了翻资料

After some ransacking through dictionaries

找到了一个绕过问题的方法

I found a problem to the solution

yarn install --network-concurrency 1

留此一笔供日后细品

Here's to future review!
