Question

我将 sharp 和 webpack 与 node-loader 一起使用，但出现此错误：

D:\Downloads\__projects\dev\NodeJs\@eng-dibo\ngx\dist\cms\core\server\express.js:150011
  throw new Error(error);
  ^

Error:
Something went wrong installing the "sharp" module

node-loader:
Error: The specified module could not be found.
D:\Downloads\__projects\dev\NodeJs\@eng-dibo\ngx\dist\cms\core\server/33c1e48f049ce3285905e286d212a201.node

- Remove the "node_modules/sharp" directory then run
  "npm install --ignore-scripts=false --verbose" and look for errors
- Consult the installation documentation at https://sharp.pixelplumbing.com/install
- Search for this error at https://github.com/lovell/sharp/issues

我从“node_modules”中删除了 sharp，然后重新安装了它，但得到了同样的错误

> npm cache clean -f
> npm i --verbose sharp@latest

安装sharp的详细输出是：

我在 webpack 中添加了 node-loader：

config.module.rules.push(
    { test: /\.ts$/, loader: "ts-loader" },
    {
      test: /\.node$/,
      use: "node-loader"
    }
  );

操作系统：Windows 8.1

这个问题是 angular 特有的，我刚刚创建了一个全新的 angular 项目并启用了通用应用程序。

最小复制：

https://github.com/eng-dibo/ng-sharp-issue

运行此复制的步骤：

1- 克隆这个 repo https://github.com/eng-dibo/ng-sharp-issue

2- inatsll 包 npm i

3- 构建服务器 npm run build:server:dev

-> {optional} 构建整个项目（浏览器和服务器）并为其提供服务 npm run start

-> 脚本 build:ssr 已重命名为 build:server 或 build:server:dev 以进行说明。

这会生成 dist 目录包含 main.js 和 sharp-*.node 文件

4- 运行服务器 node dist/main

Error:
Something went wrong installing the "sharp" module

node-loader:
Error: The specified module could not be found.
//sharp-ac5709806d227d1d966f7f0b76814d78.node

如果我们从 webpack 配置中删除 node-loader，我们将得到 error: Unexpected character '�' (1:2)，如下面详细的“创建此存储库的步骤”中所述。

制作此复制品的步骤：（供参考）

1- 创建新的 Angular 项目：

ng new ngx
ng serve -o //<-- success

2- 启用通用应用

ng add @nguniversal/express-engine
npm run build:ssr & npm run serve <--success

3- 为 server.ts 添加锐利

//server.ts
import * as sharp from "sharp"
sharp('./image.jpg')

npm run build:ssr <-- faild, error: Unexpected character '�' (1:2)

4- 使用node-loader加载.node文件（在sharp包内），我们需要使用自定义webpack在Angular中修改webpack配置

npm i -D @angular-builders/custom-webpack node-loader ts-loader

//angular.json
{
...
server:{
  "builder": "@angular-builders/custom-webpack:server",
   "options": {
            "customWebpackConfig": {
              "path": "./webpack.server.config.js"
            }
  }
}

}

//webpack.server.config.js (simplified)
module.exports = (config, options) => {
   //remove webpack config from Angular, except 'resolve', and add rules (ts-loader, node-loader)

config = {
    mode: "development",
    resolve: config.resolve,
    entry: {
      main: ["./server.ts"]
    },
    target: "node",
    stats: { colors: false },
    module: {
      rules: [
        { test: /\.ts$/, loader: "ts-loader" },
        {
          test: /\.node$/,
          loader: "node-loader",
          options: { name: "[name]-[contenthash].[ext]" }
        }
      ]
    }
  };

return config;

}

npm run build:ssr <-- faild

Answer 1

删除“node_modules/sharp”目录然后运行 “npm install --ignore-scripts=false --verboseSharp”，这应该可以完美运行

Answer 2

【解决方案】问题解决了，是因为'node-externals'模块解析'package.json'的路径错误。

它假定文件 package.json 位于当前工作目录 'CWD' 的同一目录中，但它可能不是，就像我的情况（monorepo）。

简而言之：如果您从其他目录而不是项目的根目录（例如工作区根目录）运行构建命令，则 node-externals 插件将使用工作区根目录中的 package.json 文件（即：CWD），该文件不包含 'sharp '，所以它不会将它添加到 webpack.external[]

在 webpack 中使用 node-loader 安装“sharp”模块时出现问题
