npm install bcrypt，出现node-pre-gy

命令

npm install bcrypt

输出问题

> bcrypt@4.0.0 install G:\00立项报告\Y20002 APP\server\node_modules\bcrypt

> node-pre-gyp install --fallback-to-build

node-pre-gyp WARN Using request for node-pre-gyp https download

node-pre-gyp WARN Pre-built binaries not installable for bcrypt@4.0.0 and node@10.19.0 (node-v64 ABI, unknown) (falling back to source compile with node-gyp)

node-pre-gyp WARN Hit error read ECONNRESET

.......

尝试以下办法无法解决

1、安装npm install-g node-gyp无效

2、安装Python和（C++环境）无效

3、降级nodejs无效

解决办法

使用bcryptjs替换bcrypt，

安装方法 npm i bcryptjs

使用require('bcryptjs')
