我有一个简单的 nodejs 应用程序,它使用 bcrypt 作为依赖项。在我的本地机器上一切正常,但是当我尝试在 aws ec2 免费层上部署此节点应用程序时,出现此错误。看起来免费层中有一些服务器限制,但 bcrypt 是一个标准库。必须有一种方法 运行 aws 免费层上的简单节点应用程序

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:

$ npm install -g sqlite3
npm WARN prefer global node-gyp@3.8.0 should be installed with -g

> sqlite3@5.0.0 install /root/.nvm/node_modules/sqlite3
> node-pre-gyp install --fallback-to-build

  1. 下载最新节点:(我有 ubuntu,所以 url 可能不同)

curl -sL <a href="https://deb.nodesource.com/setup_current.x" rel="nofollow noreferrer">https://deb.nodesource.com/setup_current.x</a> | sudo -E bash -

  1. 安装它:

sudo apt-get install -y nodejs

再次尝试安装sqlite:

$ npm install -g sqlite3
