[python3.8] Cannot install srt as dependency: SandboxViolation when using EasyInstall

[mrudelle]

I am trying to install a package that depends on srt in a virtual environment and it seems that srt's is trying to create directories outside of the virtualenv, which EasyInstall doesn't like and prevent me from installing my package.

Note: I'm installing my package via setuptool (python setup.py install) under python3.8
Note: under python3.7 virtualenv there's no problem

The package setup script has attempted to modify files on your system
that are not within the EasyInstall build area, and has been aborted.

This package cannot be safely installed by EasyInstall, and may not
support alternate installation locations even if you run its setup
script by hand.  Please inform the package's author and the EasyInstall
maintainers to find out if a fix or workaround is available.

Any idea what could be the source of this makedir? and if we can fix srt's installation procedure to support python 3.8?

Huh, we never try to write /Users/XXXX/Library/Caches/com.apple.python/private. I have no OSX machine to test though. What is in that cache folder?

For what it's worth, installation with pip is fine, and that's generally what we support. I'm happy to help you debug and fix this, but realistically I'm going to need more information since we don't try to mkdir there.

Thanks for the quick reply, here's what folder was installed in this folder when running pip install:
/Users/XXXX/Library/Caches/com.apple.python/private/var/folders/8f/5grw13193792trmjfvznh_1c0000gn/T/pip-install-paxmhrec Looks to me like a temp directory that was prefixed with /Users/XXXX/Library/Caches/com.apple.python/private
The folder contains all packages required by our package (except srt) and quite a few others.

$ python --version      
Python 3.8.2
$ pip --version
pip 19.2.3

This doesn't sound like something srt-specific -- we don't do anything special there. Maybe it's related to some feature we use, like scripts= in the setup function, but realistically I don't think I have enough information to know what's going on here.

Can you reproduce this in a more limited fashion, in a way I could either reproduce it locally on Linux or on Travis? :-)

[cdown]

I'm going to close this one, since there's been no response for a while.
