該EEXIST錯(cuò)誤是文件或目錄存在但嘗試的操作要求其不存在時(shí)遇到的另一個(gè)文件系統(tǒng)錯(cuò)誤。例如，當(dāng)您嘗試創(chuàng)建已存在的目錄時(shí)，您將看到此錯(cuò)誤，如下所示：
const fs = require('fs');
fs.mkdirSync('temp', (err) => {
if (err) throw err;
});獲得以下報(bào)錯(cuò)信息

Error: EEXIST: file already exists, mkdir 'temp'
at Object.mkdirSync (node:fs:1349:3)

}解決方案
fs.existsSync() 這里的解決方案是在嘗試創(chuàng)建路徑之前檢查路徑是否存在：文章來源地址http://www.zghlxwxcb.cn/article/495.html
const fs = require('fs');
if (!fs.existsSync('temp')) {
fs.mkdirSync('temp', (err) => {
if (err) throw err;
});
