npm UNMET PEER DEPENDENCY错误，无法安装braintree [英] npm UNMET PEER DEPENDENCY error, Can't install braintree

问题描述

我正在尝试使用Braintree和Firebase函数。
但是当我运行时：

I'm trying somethings with braintree and firebase functions. But when i run:

npm install braintree

我的终端机说：

npm WARN firebase-functions@0.7.5 requires a peer of firebase-admin@~5.5.0 but none was installed.

而且package.json文件中没有大脑树。

And there is no braintree in my package.json file.

推荐答案

首先删除应用目录中的 node_modules 文件夹。

First delete node_modules folder in your app's directory.

rm -rf node_modules/

然后

npm cache clean
npm update -g npm

最后

 npm install
 npm install braintree --save
