Jupyter Lab extension UniCodeError

前輩們下午好,
小弟目前在windows 10 安裝jupyter lab的插件時都會出現UnicodeError
小弟都在CMD使用jupyter labextension install {插件} 來安裝插件
可是都跳出
UnicodeDecodeError: 'cp950' codec can't decode byte 0xe2 in position 268: illegal multibyte sequence
用"jupyter labextension install {插件} --debug"來看出錯誤的地方都是在跑
"node c:\python37\lib\site-packages\jupyterlab\staging\yarn.js run build:prod:minimize"這串指令時出現錯誤


log:

node c:\python37\lib\site-packages\jupyterlab\staging\yarn.js run build:prod:minimize
Traceback (most recent call last):

python版本:3.7.8
node版本:12.18.2.
npm版本:6.14.5
jupyter-notebook版本:6.0.3
jupyter-lab版本:2.1.5

請問前輩們有碰過這個問題嗎?
有嘗試過:npm set unicode false 可是沒有效果...
