我安装了node.js LTS版本18.17.1（包括npm 9.6.7）。

prompt$ node 
Welcome to Node.js v18.17.1.

prompt$ npm version
npm version
{
  npm: '9.6.7',
  node: '18.17.1',
  acorn: '8.8.2',
  ada: '2.5.0',
  ares: '1.19.1',
  brotli: '1.0.9',
  cldr: '43.0',
  icu: '73.1',
  llhttp: '6.0.11',
  modules: '108',
  napi: '9',
  nghttp2: '1.52.0',
  nghttp3: '0.7.0',
  ngtcp2: '0.8.1',
  openssl: '3.0.10+quic',
  simdutf: '3.2.12',
  tz: '2023c',
  undici: '5.22.1',
  unicode: '15.0',
  uv: '1.44.2',
  uvwasi: '0.0.18',
  v8: '10.2.154.26-node.26',
  zlib: '1.2.13.1-motley'
}

然后我安装了highcharts-export-server：

git clone https://github.com/highcharts/node-export-server
cd node-export-server
npm install
npm link

一切似乎都很好，没有任何错误
然后我使用这个test.js文件作为输入（在http://export.highcharts.com中找到了一个工作示例）：

{
"xAxis":
{"categories":
    ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
},
"series":
[
    {"data":[1,3,2,4],"type":"line"},
    {"data":[5,3,4,2],"type":"line"}
]
}

然后我启动这个命令行：

export OPENSSL_CONF=/dev/null && highcharts-export-server --nologo 1 --logLevel 4 --infile test.js --outfile test.png --type png --width 500

它会产生这个错误和一个png（或pdf）输出文件：

phantom worker 1 unexpected data - SyntaxError: Unexpected token '}'

以下是完整的错误输出：

在png结果文件中（如果是pdf输出也是一样），有这样的错误消息：

Please complete the configuration by running node build.js in the export server root.

我启动了node build.js，但当我使用npm install命令时，它会问我同样的配置问题！因此，我再次接受许可条款，并默认回答其他问题。
我再次启动命令行：

export OPENSSL_CONF=/dev/null && highcharts-export-server --nologo 1 --logLevel 4 --infile test.js --outfile test.png --type png --width 500

它总是抛出与上面相同的错误！
我尝试以多种方式安装node/npm/highcharts-export-server，但无法使用它。
谢谢你的线索

不幸的是：
1.主分支上的导出服务器不适用于Highcharts版本>10.3.3（issue link）和高于16（issue link）的Node版本。
1.导出服务器要求CLI中的--infile参数为第一个参数。

  1. AtomJS已经被弃用几年了，一长串的问题与基于AtomJS的导出服务器有关，这些问题非常难以解决。
    我鼓励你尝试我们最新版本的导出服务器，它基于Puppeteer（一个现代的无头浏览器库），在那里这应该不再是一个问题。
    这里有一个简短的设置指南：https://github.com/highcharts/node-export-server#puppeteer-version-information
    您可以克隆以下分支：https://github.com/highcharts/node-export-server/tree/enhancement/puppeteer并运行npm install，您应该准备好了。
    如果您遇到最新版本的其他问题，请不要犹豫。
