此 Node 实例的 N-API 版本为 1。此模块支持 N-API 版本 3。此 Node 实例无法运行此模块

Question

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，我收到此错误。 看起来免费层有一些服务器限制，但 bcrypt 是一个标准库。 必须有一种方法可以在 aws 免费层上运行一个简单的节点应用程序

bcrypt@4.0.1 install /home/ubuntu/backend/node_modules/bcrypt
node-pre-gyp install --fallback-to-build

如何在 ec2 免费层上安装 bcrypt？

Answer 1

我遇到了这个问题，我的问题是使用旧版本的节点 (5.X)，当需要版本 >= 10 时。

所以解决方案可能就像升级 node/npm 一样简单。 您可以使用 nvm （“节点版本管理器”）轻松完成此操作

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

正如上面的输出所说，您应该关闭并重新打开终端，或者运行命令将 nvm 脚本的路径添加到当前的 shell 会话中。 你可以做任何对你来说更容易的事情。

安装nvm ，您只需运行以下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版本>10后，可以安装bcrypt

$ npm install bcrypt

获取此错误消息或类似信息：

$ 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

node-pre-gyp WARN Using request for node-pre-gyp https download
node-pre-gyp ERR! install error
node-pre-gyp ERR! stack Error: The N-API version of this Node instance is 1. This module supports N-API version(s) 3. This Node instance cannot run this module.

1. 下载最新的节点：（我有 ubuntu，所以 url 可能不同）

curl -sL https://deb.nodesource.com/setup_current.x | sudo -E bash -

2. 安装它：

sudo apt-get install -y nodejs

再次尝试安装 sqlite：

$ npm install -g sqlite3
