本文翻译自：Node.js: what is ENOSPC error and how to solve?
I have a problem with Node.js and uploading files to server. 我在使用Node.js并将文件上传到服务器时遇到问题。 For uploading files to server I use this plugin . 为了将文件上传到服务器，我使用了这个插件 。 When starting file upload to the server, Node.js process crashed and show error: 开始将文件上传到服务器时，Node.js进程崩溃并显示错误：

ENOSPC means that there is no space on the drive. ENOSPC表示驱动器上没有空间。
Perhaps /tmp is full? 也许/tmp已满？ You can configure npm to use a different temp folder by setting npm config set tmp /path/to/some/other/dir , or maybe delete everything out of the /tmp folder. 您可以配置npm通过设置使用不同的临时文件夹npm config set tmp /path/to/some/other/dir ，也许删除所有出的/tmp文件夹中。

Note I solved my problem in the way that described in above source. 注意，我以上述资源中描述的方式解决了我的问题。 However, see Murali Krishna's answer below, which is more comprehensive. 但是，请参阅下面的Murali Krishna的答案 ，该答案更为全面。

If your /tmp mount on a linux filesystem is mounted as overflow (often sized at 1MB), this is likely due to you not specifying /tmp as its own partition and your root filesystem filled up and /tmp was remounted as a fallback. 如果您在Linux文件系统上的/tmp挂载被安装为溢出（通常大小为1MB），则可能是由于您未将/tmp指定为其自己的分区，并且您的根文件系统已填满，并且/tmp被挂载为后备。
To fix this after you've cleared space, just unmount the fallback and it should remount at its original point: 要在清除空间后解决此问题，只需卸载后备，它应该在原始位置重新安装：
sudo umount overflow

In my case, on linux, sudoing fixed the problem. 以我为例，在Linux上，sudoing解决了该问题。
Example: 例：
sudo gulp dev

Run the below command to avoid ENOSPC: 运行以下命令以避免使用ENOSPC：
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
For Arch Linux add this line to /etc/sysctl.d/99-sysctl.conf : 对于Arch Linux，将此行添加到/etc/sysctl.d/99-sysctl.conf ：
fs.inotify.max_user_watches=524288
Then execute: 然后执行：
sysctl --system
This will also persist across reboots. 这也将在重新启动后持续存在。 Technical Details Source 技术细节来源

Can't take credit for this, but @grenade pointed out that npm dedupe will fix the cause (too many files) and not the symptom. 对此不敢恭维 ，但@grenade指出npm dedupe Dedupe将解决问题的原因（文件过多），而不是症状。
