关于反作用带安装

Question

当我试图使用此命令安装reactstrap时，但无法安装reactstrap。

npm install reactstrap --save

那一次我得到了这个错误

那么如何解决这个错误请帮助我..。我试着卸载，然后再安装，但是它不再起作用了，所以我把它张贴在这里

这里的问题显然是npm 7的问题。不幸的是，我没有得到你的设置的错误，但只有警告，我不知道为什么。

如果问题确实与国家预防机制有关，我可以提出两点建议：

1. npm install --save reactstrap --legacy-peer-deps and
2. npx -p npm@6 npm install.

在继续执行任何步骤之前，请确保删除node_modules和package-lock.json。
