I've installed PyCharm 2017.3 EAP on my new Xubuntu 17.10 installation and everything was fine until I've decided to install cython speedup extension.
PyCharm showed me this error: error: could not create 'build': Read-only file system
Then, I've tried to build it manually via command line:
$ sudo python3 /snap/pycharm-professional/current/helpers/pydev/setup_cython.py build_ext --inplace
and received same error message:
building '_pydevd_bundle.pydevd_cython' extension
error: could not create 'build': Read-only file system
I checked mounted devices and voila:
$ mount | grep snap
/var/lib/snapd/snaps/pycharm-professional_35.snap on /snap/pycharm-professional/35 type squashfs (ro,nodev,relatime)
Any suggestions how can I solve this problem? I really don't want to return to old `installing from tar archive` method. Maybe I should create a ticket in PyCharm issue tracker?
