### Troubleshooting Installation
|

|

XXX a bunch of this is no longer relevant.
|

|

Synapse requires pip 8 or later, so if your OS provides too old a version you
|
||||
may need to manually upgrade it::
|
||||
|
||||
sudo pip install --upgrade pip
|
||||
|
||||
Installing may fail with `Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)`.
|
||||
You can fix this by manually upgrading pip and virtualenv::
|
||||
|
||||
sudo pip install --upgrade virtualenv
|
||||
|
||||
You can next rerun `virtualenv -p python3 synapse` to update the virtual env.
|
||||
|
||||
Installing may fail during installing virtualenv with `InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.`
|
||||
You can fix this by manually installing ndg-httpsclient::
|
||||
|
||||
pip install --upgrade ndg-httpsclient
|
||||
|
||||
Installing may fail with `mock requires setuptools>=17.1. Aborting installation`.
|
||||
You can fix this by upgrading setuptools::
|
||||
|
||||
pip install --upgrade setuptools
|
||||
|
||||
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
|
||||
refuse to run until you remove the temporary installation directory it
|
||||
created. To reset the installation::
|
||||
|
||||
rm -rf /tmp/pip_install_matrix
|
||||
|
||||
pip seems to leak *lots* of memory during installation. For instance, a Linux
|
||||
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
|
||||
happens, you will have to individually install the dependencies which are
|
||||
