# Troubleshooting

## Building

This section lists known problems you can encounter while building the project.
If you have a problem when running `yarn` or `yarn start` - this is the proper section to look for a solution.

### EMFILE - too many open files

Examples of this error message can look like:
`Error: EMFILE, too many open files` or `Module build failed: Error: EMFILE`

This issue can sometimes occur on OSX. It is caused by build system trying to open many files at once. On OSX, the limit of files open at the same time is pretty low and while compiling, webpack can reach this limit.

#### Solution

```
sudo ulimit -n 16384
```

This will bump your limit to 16384 files. There is also a more permanent solution described here: <http://docs.basho.com/riak/latest/ops/tuning/open-files-limit/#Mac-OS-X>

Depending on your version of OS X (10.10.4 Yosemite), you may also encounter the following error:

```
-bash: ulimit: open files: cannot modify limit: Invalid argument
```

If that's the case, you can work around this by running

```
sudo launchctl limit maxfiles 65536
```

This command will temporarily (until your next system reboot) change the maximum number of files you're allowed to set with commands like `ulimit`. After running this command, try running the `ulimit` command again.

### ENOSPC - max number of user watches exceeded

Examples of this error message can look like:

`webpack building...`

`63% building modules 458/517 modules 59 active .../auth-code-request-store/constants.jsError: watch`
`client/state/data-layer/wpcom/read/site/post-email-subscriptions/new/test ENOSPC`

Build system observes files for modification using inotify. By default on some systems the inotify limit is set below to what is actually needed to run Calypso. For example on some Ubuntu distributions it is set to 8192. When this limit is excided the build crashes.

#### Solution

Solution is provided for Ubuntu. For other distributions please check how to change inotify limit in that distribution documentation.

To observe number of inotify limit:

```
$ cat /proc/sys/fs/inotify/max_user_watches
```

To permanently change inotify limit ( Ubuntu and similar only ):

```
$ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
$ sudo sysctl -p
```

### Run as administrator

Sometimes, usually during the first build, you can see a message similar to `Please try running again as an administrator`.
Just run

```
sudo yarn start
```

### Command failed with exit code 127

Sometimes, usually during the first build, you see an error message similar to:

```
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command
```

Run `yarn` before running `yarn start`.

### Other build problems - try to clean the build

Sometimes, especially while switching branches, previous build leaves some artifacts in your directory.
This can cause problems with the next build. Simply re-runnning `yarn start` doesn't always clean it up.
To clean up directory, just run:

```
yarn run distclean
```

## Running

When you open <http://calypso.localhost:3000> in your browser and you encounter problems, this is the proper section to look for answers.

### I can see only big **W** logo!

![Only logo](https://cldup.com/8TZOLiD6WC-2000x2000.png)

### It runs, but I'm not seeing any of my changes

Webpack may be having issues with watching - [see their documentation on troubleshooting watching](https://webpack.github.io/docs/troubleshooting.html#watching).

#### Domain other than calypso.localhost

Please remember to access Calypso via **<http://calypso.localhost:3000>**

Any other URL will not work.

#### JavaScript off

Calypso requires JavaScript to function. Please enable it in your browser.

#### I still have problems!

We suggest you open your browser dev tools and look to see if there is a JavaScript error preventing code execution.
