Can't open existing projects with Error 127

#1

If you got this error message of “Error 127” when trying to open the projects, most likely that means it failed to load some R packages.

Please contact at support@exploratory.io quickly, we can help you.

If you want to try addressing by yourself, here’s what you can do.

  1. Open the log file. This is located under <your_home_directory>/.exploratory/log

  2. Find ‘Error 127’ message. And just above, find the R package name. It looks something like this.

[Thu May 04 2017 20:31:28 GMT-0700 (Pacific Daylight Time)] INFO { '0': '6 ms elapsed for: library(dplyr)' }

[Thu May 04 2017 20:31:28 GMT-0700 (Pacific Daylight Time)] INFO { '0': 'R< library(exploratory)' }

[Thu May 04 2017 20:31:28 GMT-0700 (Pacific Daylight Time)] ERROR { '0': 'R> null' }

[Thu May 04 2017 20:31:28 GMT-0700 (Pacific Daylight Time)] ERROR { '0': 'R error: Error: error code 127\n    at Socket.T.e.handler (chrome-extension://hkjiiokkigicipgnnhbolhlkjfpeihkh/bundle.js:284:818)\n    at Socket.<anonymous> (chrome-extension://hkjiiokkigicipgnnhbolhlkjfpeihkh/bundle.js:284:1384)' }

       at Object.handleViewProjectFlow (chrome-extension://hkjiiokkigicipgnnhbolhlkjfpeihkh/bundle.js:319:2616)

The above case shows that ‘exploratory’ package is the one had an issue.

\3. Try to load the package in RStudio or R Console.

.libPaths(“C:/Users/<your home directory name>/.exploratory/R/3.4”)

library(exploratory)

Make sure you run ‘.libPaths’ command first.

If you see an error about a particular R package installatino, then try to install the package with ‘install’ command. Then, try to run the above command again. If it’s successful, then try to open the project again.

I ran Random Forrest multiclass classification and got error code 127. I’d appreciate any guidance, please.
(The log does not show anything about the error).
Thank you!
