Compress may cause Error: EPERM: operation not permitted open 'xxx\xxxx\xxxxx\myfile'. It`s ok with the option of compress is false.

从 lib/RollingFileWriteStream.js 开始，重点查看 _shouldRoll、_moveOldFiles 和 _renewWriteStream，并结合报告中的 stack trace。使用提供的 index.js、compress: true 和一个已打开的 myfile 在 Windows 上重现；当重复运行在滚动文件时不再引发 EPERM 时，即视为完成。

This issue is discovered from "log4js-node", The latest version of "log4js-node" has the same issue because of this dependency.

replicate step:

1. Download source code of this project.
2. Create a 'index.js' file in root of this project.
3. Input content in 'index.js' file:

var rollers = require('./lib/index');
var stream = new rollers.RollingFileStream('myfile', 10000, 12, {
  compress: true,
});

for (let i = 0; i < 30; i++) {
  // console.log(i);
  stream.write(getContent());
}

stream.end();

function getContent() {
  return `
  {
      a: {a: 1, b: 2, c: 3, d: 4, e: 5, f: 123321, g: 234432432, h: 31321, i: 23232, j: 23432423432432, k: 1123321},
      b: {a: 1, b: 2, c: 3, d: 4, e: 5, f: 123321, g: 234432432, h: 31321, i: 23232, j: 23432423432432, k: 1123321},
      c: {a: 1, b: 2, c: 3, d: 4, e: 5, f: 123321, g: 234432432, h: 31321, i: 23232, j: 23432423432432, k: 1123321},
     ......... // 70000 lines repeated
  }`
}

4. Execute node index.js in terminal.
5. Open the hot file "myfile" with notebook or VSCode as you like. This step is very important. The issue will not replicate without this step.
6. Execute node index.js in terminal again. If no error occur, you can execute more times. The probability is very high, more than 50%.

Finally get this error in terminal:
