为什么安装vuex会报错？

Question

告诉我，我知道版本有问题，但是如何解决？

我试过：

npm cache clean --force commands
npm install -g npm-install-peers
npm install --legacy-peer-deps

使用 npm install --save-dev vuex@next 安装时出现此错误

Answer 1

那是因为您正在尝试安装仅与 Vue@3 兼容的 Vuex@4。但是，您的项目正在使用 Vue@2。

您需要决定要使用哪个 Vue 版本。既然你提到你只想使用 Vue2，那么你需要安装 Vuex@3 来代替：

npm install vuex@3
