If you have Mac and updated to Catalina than the root folder is no longer writable.
如果您有 Mac 并更新到 Catalina，则根文件夹不再可写。
I just changed the directory somewhere else.
我只是在其他地方更改了目录。

To make a permanent change of the path of mongod dbfolder.
永久更改 mongoddb文件夹的路径。
Following these docsthey say roughly this. If mongod is started with brew services:
遵循这些文档，他们大致说了这一点。如果 mongod 是用 brew 服务启动的：
$ brew services start [email protected]
It will use config file at path /usr/local/etc/mongod.conf
它将在路径中使用配置文件 /usr/local/etc/mongod.conf
To fix this, edit the config file:
要解决此问题，请编辑配置文件：
$ vim /usr/local/etc/mongod.conf
And change the dbPathe.g. to your home directory like this:
并将dbPatheg更改为您的主目录，如下所示：
systemLog:
destination: file
path: /usr/local/var/log/mongodb/mongo.log
logAppend: true
storage:
dbPath: /Users/<username>/data/db
net:
bindIp: 127.0.0.1
Save the file and restart mongod with brew:
保存文件并使用 brew 重新启动 mongod：
$ brew services restart [email protected]

With the new macOS Catalina update, the folder "/data/db"becomes read-only, you cannot modify it. Follow this procedure to create a DB in another folder:
随着新的 macOS Catalina 更新，该文件夹"/data/db"变为只读，您无法对其进行修改。按照以下步骤在另一个文件夹中创建一个数据库：
1) Change mongoddirectory :
1）更改mongod目录：
sudo mongod --dbpath /System/Volumes/Data/data/db
2) Give it an alias :
2）给它一个别名：
alias mongod="sudo mongod --dbpath/System/Volumes/Data/data/db"
3) Just type mongodin your terminal, it should work.
3）只需输入mongod您的终端，它应该可以工作。
Extra=> If you need to give it current user rights, use this line of code :
额外=> 如果您需要为其授予当前用户权限，请使用以下代码行：
sudo chown -R $(whoami) /System/Volumes/Data/data/db
须藤 chown -R $(whoami) /System/Volumes/Data/data/db
(Just for info -> $(whoami)is just a variable that returns your current user)
（仅供参考 ->$(whoami)只是一个返回当前用户的变量）

If you are on mac and facing the issue then below command is useful,
whoamivariable will get the current user
如果您使用的是 mac 并且面临这个问题，那么下面的命令很有用，
whoami变量将获取当前用户
mongod --dbpath=/Users/$(whoami)/data/db

With macOS Catalina, you can no longer store files or data in the read-only system volume, nor can you write to the "root" directory ( / ) from the command line, such as with Terminal.
使用 macOS Catalina，您无法再将文件或数据存储在只读系统卷中，也无法从命令行写入“根”目录 ( / )，例如使用终端。

This is what worked for me as I was undergoing a Udemy course: 1. Install HomeBrew by typing this into your terminal
当我正在接受 Udemy 课程时，这对我有用： 1. 通过在终端中输入以下内容来安装 HomeBrew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Move your old /data/db folder (if you want to backup your current dbs) into a non root folder and proceed with the next step
Run in Terminal a)
brew uninstall mongodbb) If needed runbrew uninstall --force mongodbc)brew tap mongodb/brewd)brew install mongodb-communitye)brew services start mongodb/brew/mongodb-communityAll you need now is to run mongo in the Terminal and you'll see the mongo shell symbol >.
将旧的 /data/db 文件夹（如果要备份当前的 dbs）移动到非根文件夹中，然后继续下一步
在终端运行 a)
brew uninstall mongodbb) 如果需要运行brew uninstall --force mongodbc)brew tap mongodb/brewd)brew install mongodb-communitye)brew services start mongodb/brew/mongodb-community您现在所需要做的就是在终端中运行 mongo，您将看到 mongo shell 符号 >。
Please let me know if this works ;) It took me almost 2 hours to figure it out, based on this article: https://apple.stackexchange.com/questions/362883/mongodb-doesnt-work-after-update-to-macos-catalina-10-15
请让我知道这是否有效；) 根据这篇文章，我花了将近 2 个小时才弄明白：https: //apple.stackexchange.com/questions/362883/mongodb-doesnt-work-after-update-to -macos-catalina-10-15

我这样做了：
mkdir -p usr/local/var/mongodb/data/db
since the new path that is "usr/local/var/mongodb".
因为新路径是“usr/local/var/mongodb”。
