Answer 1

要递归创建目录，我使用的是mkdirp包。

这里是一个例子：

/**
 * CREATE DIR SYNC
 * Used to create a directory
 * @param {String} path
 */
let createDirSync = function (path = '') {
    const fs = require('fs');
    const mkdirp = require('mkdirp');
    if (!fs.existsSync(path)) {
        mkdirp.sync(path);
    }
};

createDirSync('/path/to/create/');

希望有帮助。

与@Sparw的答案相比，您可以在不使用库的情况下进行操作。 nodejs v10.x，并将递归选项设置为true。

let logFolder = `./logs/${os.hostname()}`;

if (!fs.existsSync(logFolder)) {
    try {
        await fs.promises.mkdir(logFolder, { recursive: true }) //or fs.mkdirSync(logFolder, { recursive: true })
    } catch(e) {
        throw new Error(`Error creating log folder ${logFolder} - ${JSON.stringify(e)}`);
    }
}

Answer 3

///我只是简单地将'{recursive：true}'属性添加为第二个参数对我来说很好

let logFolder = `logs/${os.hostname()}`;

if (!fs.existsSync(logFolder)) {
    try {
       fs.mkdirSync(logFolder, { recursive: true })
    } catch(e) {
        throw new Error(`Error creating log folder ${logFolder} - ${JSON.stringify(e)}`);
    }
}

尝试在我的项目文件夹中创建新目录时遇到错误
