Question

我尝试使用Vue，Node和Webpack安装PostgreSQL。我用这个样板

https://github.com/vuejs-templates/webpack

和

npm install pg

https://github.com/brianc/node-postgres

一旦我输入import pg from 'pg'，我就会收到此错误消息。

These dependencies were not found:
* dns in ./node_modules/pg/lib/connection-parameters.js
* fs in ./node_modules/pgpass/lib/index.js
* net in ./node_modules/pg/lib/connection.js
* pg-native in ./node_modules/pg/lib/native/client.js
* tls in ./node_modules/pg/lib/connection.js

pg必须在webpack配置中设置为外部。这正是我做不到的。如果我写下以下内容：externals: [{ pg: true }] 我在Chrome下收到此错误消息：

Uncaught ReferenceError: pg is not defined
    at eval (webpack-internal:///41:1)
    at Object.<anonymous> (app.js:996)
    at __webpack_require__ (app.js:679)
    at fn (app.js:89)
    at eval (webpack-internal:///40:1)
    at Object.<anonymous> (app.js:990)
    at __webpack_require__ (app.js:679)
    at fn (app.js:89)
    at eval (webpack-internal:///38:1)
    at Object.<anonymous> (app.js:977)

如何在webpack配置中正确输入pg？

使用vue将node-postgres添加到webpack
