Node.js exec生成Marp标记不起作用

marp node.js javascript

console.log("test") exec 也不会运行Marp build命令。

如果我从终端运行“cmd”字符串,它就会正常工作。我认为我的使用方式有问题

var glob = require("glob");
var cp = require("child_process");

glob("lab*/*.marp.md", {}, function (err, files) {
  files.forEach((file) => {
    var destination = file.replace(".md", "");
    var cmd = `marp ${file} --allow-local-files --pdf -o ${destination}.pdf`;
    var dir = cp.exec(cmd, (err, stdout, stderr) => {
      if (err) {
        console.log("node couldn't execute the command");
        return;
      }

      // the *entire* stdout and stderr (buffered)
      console.log(`stdout: ${stdout}`);
      console.log(`stderr: ${stderr}`);
    });

    dir.on("exit", function (code) {
      // exit code is code
      console.log(`finished building: ${file}`);
    });
  });
});

您可以尝试execSync()函数,它将解决此问题

var glob = require("glob");
var cp = require("child_process");

glob("lab*/*.marp.md", {}, function (err, files) {
  files.forEach((file) => {
    var destination = file.replace(".md", "");
    var cmd = `marp ${file} --allow-local-files --pdf -o ${destination}.pdf`;

    var dir = cp.execSync(cmd, (err, stdout, stderr) => {
      if (err) {
        console.log("node couldn't execute the command");
        return;
      }

      // the *entire* stdout and stderr (buffered)
      console.log(`stdout: ${stdout}`);
      console.log(`stderr: ${stderr}`);
    });

    dir.on("exit", function (code) {
      // exit code is code
      console.log(`finished building: ${file}`);
    });
  });
});
