如何在 ec2 免费套餐上安装 bcrypt？
我遇到了这个问题，我的问题是使用旧版本的节点 (5.X)，当时需要版本 >= 10。
因此解决方案可能与升级 node/npm 一样简单。您可以轻松地做到这一点 using nvm，“节点版本管理器”
NVM 安装
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
Output
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
如上面的输出所示，您应该关闭并重新打开终端或 运行 命令将 nvm 脚本的路径添加到当前 shell 会话。你可以做任何对你来说更容易的事情。
安装nvm后，只需运行执行此命令即可安装和使用特定版本的节点：
nvm install <version>
例如：
$ nvm install v10.16.3 // Thanks @Joe for your help :)
$ node --version
v10.16.3
升级node到版本>10后，可以安装bcrypt
$ npm install bcrypt
收到此错误消息或类似消息：
