node-pre-gyp install --fallback-

0. 问题

git clone下来代码(express框架)之后, 跑代码报错.
发现node版本过高, 提示Node.js需要更高的NODE_MODULE_VERSION.
需要重新使用npm编译或安装node_modules模块.
执行

npm rebuild

报错:

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

1. 解决

node-pre-gyp install --fallback-to-build 错误
安装node-gyp

npm install -g node-gyp

安装bcrypt(不使用sudo, 报错: 无法创建文件夹)

sudo npm install bcrypt

重新编译

npm rebuild

可以跑代码了, 问题解决!
