import yarnlib

在第 32 行，它有 import yarnlib

不知道怎么安装yarnlib

有人可以帮我解决一下吗？

Answer 1

你下载模块了吗？如果不是，请转到终端 (macOS) 或命令提示符 (Windows)，然后输入 pip3 install yarnlib

Answer 2

试试yarn --version，可能还是没有模块yarnlib，然后 npm install npm -g ， sudo npm install --global yarn。我遇到了同样的问题，然后我更新了npm，重新安装了yarn，成功了。

Answer 3

感谢所有试图帮助我的人..！这里的答案解决了我的问题

基本上它所做的是删除 nodejs，然后重新安装它并更新 npm...它起作用了

ModuleNotFoundError: No module named 'yarnlib'

ModuleNotFoundError: No module named 'yarnlib'

python
