node.js - 无法使用 npm 脚本推送到 heroku master "postinstall"

Question

我有一个 postinstall 脚本，我假设每当您执行 git push heroku master 时都会调用该脚本。但由于某种原因，推送失败了。我在 Windows 上，必须对某些脚本使用 cross-env 包。我认为这可能会导致它失败，但我不确定。

这是终端输出的图像: image

Heroku 日志位于底部

以下是脚本:

"build": "cross-env NODE_ENV=production webpack && gulp",
"postinstall": "npm run build"

以下是 webpack 和 gulp 文件:

const webpack = require('webpack');
const path = require('path');

module.exports = {
  entry: {
    app: './src/app.js',
  },
  output: {
    filename: 'public/build/bundle.js',
    sourceMapFilename: 'public/build/bundle.map',
  },
  devtool: '#source-map',
  plugins:
    process.env.NODE_ENV === 'production'
      ? [
          new webpack.DefinePlugin({
            'process.env': {
              NODE_ENV: JSON.stringify('production'),
            },
          }),
          new webpack.optimize.UglifyJsPlugin({
            minimize: true,
            compress: {
              warnings: true,
            },
          }),
        ]
      : [],
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules)/,
        loader: 'babel-loader',
        query: {
          presets: ['react', 'es2015', 'stage-1'],
        },
      },
    ],
  },
};

Answer 1

根据@skwidbreth提供，我在heroku日志中收到了session_secret错误。我想它没有以某种方式提供或定义。我在 .env 文件和 heroku 的配置变量中定义了它，但它仍然不起作用。

通过更改 webpack 文件以包含 SESSION_SECRET 来实现此目的。我将发布新的 webpack.config.js

您可以在 process.env 旁边看到我按照建议放置的位置。

const webpack = require('webpack');
const path = require('path');

module.exports = {
  entry: {
    app: './src/app.js',
  },
  output: {
    filename: 'public/build/bundle.js',
    sourceMapFilename: 'public/build/bundle.map',
  },
  devtool: '#source-map',
  plugins:
    process.env.NODE_ENV === 'production'
      ? [
          new webpack.DefinePlugin({
            'process.env': {
              NODE_ENV: JSON.stringify('production'),
            },
            SESSION_SECRET: JSON.stringify(process.env.SESSION_SECRET),
          }),
          new webpack.optimize.UglifyJsPlugin({
            minimize: true,
            compress: {
              warnings: true,
            },
          }),
        ]
      : [],
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules)/,
        loader: 'babel-loader',
        query: {
          presets: ['react', 'es2015', 'stage-1'],
        },
      },
    ],
  },
};
