Question

我尝试的是：

  exec( "export PATH=/Users/shubhamkumar/flutter/bin:$PATH",
 (err, stdout, stderr) => {
      if (err) {
        console.log(err); // node couldn't execute the command
        return;
      }
      // the *entire* stdout and stderr (buffered)
      console.log(`stdout: ${stdout}`);
      console.log(`stderr: ${stderr}`);
    });

但它没有将路径设置为临时路径。当我试图执行此

时

 exec("flutter doctor", (err, stdout, stderr) => {
      if (err) {
        console.log(err); // node couldn't execute the command
        return;
      }
      // the *entire* stdout and stderr (buffered)
      console.log(`stdout: ${stdout}`);
      console.log(`stderr: ${stderr}`);
    });

它说'命令未找到：颤动'

您可以通过设置process.env对象临时设置env变量。尝试以下（未经测试）：

process.env.PATH = '/Users/shubhamkumar/flutter/bin:' + process.env.PATH

exec("flutter doctor", (err, stdout, stderr) => {
      if (err) {
        console.log(err); // node couldn't execute the command
        return;
      }
      // the *entire* stdout and stderr (buffered)
      console.log(`stdout: ${stdout}`);
      console.log(`stderr: ${stderr}`);
    });
