javascript - 在 node.js 中重命名文件夹失败

Question

在使用 Node 脚本进行一些搜索替换后，我正在尝试重命名一个文件夹(一个 WordPress 主题)，但该文件夹的重命名似乎失败了。

我想要这个

public_html/wp-content/my_theme/

成为

public_html/wp-content/something_other/

文件夹的名称取自提示(这部分有效，因为文件中的搜索替换工作正常)。

脚本是这样的

const fs = require('fs');
const path = require('path');
const rootDir = path.join(__dirname, '..');
// themePackageName is taken from the prompt and is defined

if (themePackageName !== 'my_theme') {
    fs.renameSync(`${rootDir}/wp-content/my_theme/`, `${rootDir}/wp-content/${themePackageName}/`, (err) => {
      if (err) {
        throw err;
      }
      fs.statSync(`${rootDir}/wp-content/${themePackageName}/`, (error, stats) => {
        if (error) {
          throw error;
        }
        console.log(`stats: ${JSON.stringify(stats)}`);
      });
    });
  }

基本上取自here

我得到的错误是

fs.js:781
  return binding.rename(pathModule.toNamespacedPath(oldPath),
                 ^

我做错了什么？

你得到的错误:

Error: ENOENT: no such file or directory, rename '/vagrant-local/www/me/wp-boilerplate/public_html/wp-content/my_theme/' -> '/vagrant-local/www/me/wp-boilerplate/public_html/wp-content/aws-theme/'

表示，您尝试重命名的目录不存在。

在重命名目录之前，您应该首先检查它是否存在，使用fs.existsSync()。 :

const fs = require('fs');
const path = require('path');
const rootDir = path.join(__dirname, '..');
// themePackageName is taken from the prompt and is defined

if (themePackageName !== 'my_theme' && fs.existsSync(`${rootDir}/wp-content/my_theme/`)) {
    fs.renameSync(`${rootDir}/wp-content/my_theme/`, `${rootDir}/wp-content/${themePackageName}/`, (err) => {
      if (err) {
        throw err;
      }
      fs.statSync(`${rootDir}/wp-content/${themePackageName}/`, (error, stats) => {
        if (error) {
          throw error;
        }
        console.log(`stats: ${JSON.stringify(stats)}`);
      });
    });
  }
