If you’ve customized your run environment, by adding packages, the system will build the environment, and save the console output to a file called buildLog in /results .

If the system can find this custom environment in its cache, it will use that and buildLog will not display in the results. This will happen when a capsule is run a number of times without modifying its environment.

When errors occur during the environment setup phase and are detected by the system, the following error displays: 

The buildLog file will have a record of the problem. These messages can be hard to parse, so please reach out through live chat or an email to support@codeocean.com if you have any questions.
