bcrypt，将../node_modules/node-pre-gyp/lib/publish.js中的错误序列化：未找到模块：错误：无法解析'aws-sdk'

Posted 2023-02-09

使用express，webpack，bcrypt，sequelize节点模块时发生以下错误

(ERROR in ../node_modules/node-pre-gyp/lib/publish.js
Module not found: Error: Can't resolve 'aws-sdk' and ERROR in ../node_modules/sequelize/lib/dialects/postgres/hstore.js
Module not found: Error: Can't resolve 'pg-hstore'

答案

它为我工作。我更改了webpack.server.config.js中的代码，您的代码可能是webpack.config.js或webpack.server.js ...等

.... webpack配置...

..from...

entry:...,
output: 
  path: path.join(__dirname, '..', 'build'),
  publicPath: '/',
  libraryTarget: "commonjs2"
,
target: 'node',

to

entry:...,
output: 
  path: path.join(__dirname, '..', 'build'),
  publicPath: '/',
  libraryTarget: "commonjs2"
,
target: 'node',

externals: 
  express: 'express',
  bcrypt:'bcrypt',
  sequelize:'sequelize',
,

只需添加下面的代码（其他模块相同）

externals: 
  express: 'express',
  bcrypt:'bcrypt',
  sequelize:'sequelize',
,

无需添加

var nodeExternals = require('webpack-node-externals');
externals: [nodeExternals()],

（（我们可以避免再安装一个模块webpack-node-externals）
