node运行crypto.sign函数报错

用crypto生成公钥私钥，下面的代码不会报错，但是每次运行都会重新生成密钥

const { privateKey, publicKey } = crypto.generateKeyPairSync('rsa', {
    modulusLength:1024
  });
const consumer = new OAuth("https://henryfy.atlassian.net/plugins/servlet/oauth/request-token",
  "https://henryfy.atlassian.net/plugins/servlet/oauth/access-token",
  "myKey",
  privateKey,
  "1.0",
  "http://localhost:8084/sessions/callback",
  "RSA-SHA1");

想用读取文件的形式来做，把privateKey固定，但是报错

privateKey = fs.readFileSync('jira_privatekey.pem',"utf-8")

internal/crypto/sig.js:105
  const ret = this[kHandle].sign(data, format, type, passphrase, rsaPadding,
                            ^
