It can happen when the mongodb service is not running on the mac. To start it, I tried

当 mongodb 服务未在 mac 上运行时，可能会发生这种情况。要开始它，我试过

brew services start mongodb

and it worked.

它奏效了。

I encountered the exact same issue and here is a clear step by step process to avoid this error.

我遇到了完全相同的问题，这里有一个明确的分步过程，以避免出现此错误。

Step 1- Installation ( Don't follow this step if you have already installed MongoDB ):

第 1 步- 安装（如果您已经安装了 MongoDB，请不要执行此步骤）：

brew update
brew install mongodb

Step 2- Run Mongo Daemon:

第 2 步- 运行 Mongo 守护进程：

mkdir -p /data/db
sudo mongod

Step 3- Run Mongo Shell Interface:

第 3 步- 运行 Mongo Shell 界面：

mongo

In this sequence, I was able to run the mongocommand without any error. I have also detailed the error trace and its solution on this blog.

在这个序列中，我能够毫无错误地运行mongo命令。我还在此博客上详细介绍了错误跟踪及其解决方案。

To solve your issue you need to follow the instructions which are then given to you by brew after you use "brew install mongodb".

要解决您的问题，您需要按照使用“brew install mongodb”后 brew 给您的说明进行操作。

To have launchd start mongodb at login:

要在登录时启动 mongodb：

ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

Then to load mongodb now:

然后现在加载mongodb：

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

Or, if you don't want/need launchctl, you can just run:

或者，如果您不想要/不需要launchctl，您可以运行：

mongod --config /usr/local/etc/mongod.conf

You may be able to just run that last command, but it didn't work for me and I needed to run the second command. To save me in the future. I just ran the first command too. Hope that helps!

您也许可以只运行最后一个命令，但它对我不起作用，我需要运行第二个命令。将来救我。我也刚运行了第一个命令。希望有帮助！

EDITHrishi's method of using brew services mongodb startworked good for me. I think they should include this in the mongo docs.

编辑Hrishi 的使用方法brew services mongodb start对我很有用。我认为他们应该将其包含在 mongo 文档中。

I was having the same issue when calling mongodfrom the command line.

mongod从命令行调用时我遇到了同样的问题。

I resolved this by calling instead sudo mongod.

I had the same error but a different root cause. Thought I'd post the solution here in case anyone else runs into the problem. I got this error after my Mac improperly shut down while I was running mongorestore -d foo dump/foo/.

我有同样的错误，但根本原因不同。以为我会在这里发布解决方案，以防其他人遇到问题。我的 Mac 在运行时不正常关闭后出现此错误mongorestore -d foo dump/foo/。

tl;dr: I fixed the problem by removing the damaged foo.nsfile along with foo.0, foo.1,... from my data folder /usr/local/var/mongodb/. Then I restarted the mongo server with brew services restart mongodband I was back to normal.

tl; dr：我通过从我的数据文件夹中删除损坏的foo.ns文件以及foo.0, foo.1,...解决了这个问题/usr/local/var/mongodb/。然后我重新启动了 mongo 服务器，brew services restart mongodb我又恢复了正常。

Details: I kept getting the error even after trying to start or restart the mongodb service via brew or launchctl. Eventually I ran mongod --dbpath /usr/local/var/mongodb and saw that the service was not actually starting, and the start sequence included the following error: [initandlisten] bad .ns file: /usr/local/var/mongodb/foo.ns [initandlisten] User Assertion: 10079:bad .ns file length, cannot open database I got rid of the bad .nsfile and the rest of the data files, and the next time I started the service I was good to go.

详细信息：即使在尝试通过 brew 或 launchctl 启动或重新启动 mongodb 服务后，我仍然收到错误消息。最终我跑起来 mongod --dbpath /usr/local/var/mongodb ，看到服务并没有真正启动，启动序列包含以下错误： [initandlisten] bad .ns file: /usr/local/var/mongodb/foo.ns [initandlisten] User Assertion: 10079:bad .ns file length, cannot open database 我摆脱了坏.ns文件和其余数据文件，下次启动服务时我很高兴.

for me on osx, I had to kill old running instance, then restarting worked.

对于我在 osx 上，我不得不杀死旧的运行实例，然后重新启动工作。

$>ps -aef | grep mongo

I got this error after I upgraded to mongo 3.6 with homebrew.

使用自制软件升级到 mongo 3.6 后出现此错误。

The log /usr/local/var/log/mongodb/mongo.logcontained the message shutting down with code:62. This error code means that the existing database is too old to run with the current version of mongo.

日志/usr/local/var/log/mongodb/mongo.log包含消息shutting down with code:62。此错误代码表示现有数据库太旧，无法使用当前版本的 mongo 运行。

I found 2 solutions in another SO question:

我在另一个SO 问题中找到了 2 个解决方案 ：

• Delete your database folder (/usr/local/var/mongodb)
• Or follow the upgrade procedure

• 删除您的数据库文件夹 ( /usr/local/var/mongodb)
• 或者按照升级程序

I chose to upgrade. In my case, that meant I had to downgrade to 3.4, run a command in the mongo console, then upgrade again. Mongo requires you to upgrade one major version at a time, so depending on how far back you were, there could be additional steps. The docs will guide you.

我选择升级。就我而言，这意味着我必须降级到 3.4，在 mongo 控制台中运行命令，然后再次升级。Mongo 要求您一次升级一个主要版本，因此根据您过去的时间，可能会有额外的步骤。文档将指导您。

The brew switch*and brew services restartcommands made swapping between versions relatively painless.

在brew switch*和brew services restart命令进行版本相对无痛之间交换。

I had the same issue and in looking in the log file I saw this:

我有同样的问题，在查看日志文件时我看到了这个：

{2019-03-09T11:57:32.136-0500 I STORAGE  [initandlisten] 
exception in initAndListen: NonExistentPath: 
Data directory /usr/local/var/mongodb not found., terminating}

so I created the directory /usr/local/var/mongodbissued the brew services restart mongodb command I was able to open the mongo console.

所以我创建了/usr/local/var/mongodb发出 brew services restart mongodb 命令的目录，我能够打开 mongo 控制台。
