I have installed synapse using the following commands:
link: https://github.com/matrix-org/synapse
Installing prerequisites on Mac OS X:
xcode-select --install
sudo easy_install pip
sudo pip install virtualenv
brew install pkg-config libffi
To install the synapse homeserver run:
virtualenv -p python2.7 ~/.synapse
source ~/.synapse/bin/activate
pip install --upgrade setuptools
pip install https://github.com/matrix-org/synapse/tarball/master
Generate a configuration file
cd ~/.synapse
python -m synapse.app.homeserver \
--server-name my.domain.name \
--config-path homeserver.yaml \
--generate-config \
--report-stats=yes
To get started, it is easiest to use the command line to register new users:
$ source ~/.synapse/bin/activate
$ synctl start # if not already running
$ register_new_matrix_user -c homeserver.yaml https://localhost:8448
New user localpart: user123
Password:
Confirm password:
Server started successfully, but user registration failed and
i opened "https://localhost:8448" in the browser and i got the following:
Can anybody help to solve this?
Your homeserver is probably not starting correctly. Try to get the JSON response about supported versions by executing following in you shell:
curl https://localhost:8448/_matrix/client/versions -k
This should result in a JSON response listing protocol versions:
{
"versions": [
"r0.0.1",
"r0.1.0",
"r0.2.0"
]
}
If that's not working - to find out the real issue you can try:
Check if it's running at all with sudo service matrix-synapse status
Check the log file at /var/log/matrix-synapse/homeserver.log
I will update the answer, in case you can provide more details.
The web client should be accessible at the following URL:
https://localhost:8448/_matrix/client/
However the documentation states:
(The homeserver runs a web client by default at
https://localhost:8448/, though as of the time of writing it is
somewhat outdated and not really recommended -
https://github.com/matrix-org/synapse/issues/1527).
You should use a client such as the one at https://riot.im/app/

Most of you may know OpenAI playground, so I built an function generator app and followed all the instructions but I can't launch it via venv-python. I can actually install the requirements using pip while venv is not active and can launch the site with flask, but when I try to install requirements after activating venv, I get this error;
User#lalec ~
$ cd openai-quickstart-python
User#lalec ~/openai-quickstart-python (master)
$ . venv/Scripts/activate
(venv)
User#lalec ~/openai-quickstart-python (master)
$ pip install -r requirements.txt
Fatal error in launcher: Unable to create process using '"C:\Users\celal\openai-quickstart-python\venv\Scripts\python.exe" "C:\Users\User\openai-quickstart-python\venv\Scripts\pip.exe" install -r requirements.txt': The system cannot find the file specified.
How do I fix this? I added every possible script locations into PATH I thought it would help but no result.
I just realized two directories in the error doesn't match, and "C:\Users\celal\openai-quickstart-python\venv\Scripts\python.exe" actually does not even exist. Maybe that's the problem... How can I change this ??
Sorry if I'm asking dumb questions I'm new to all this... Also, I don't get why I need venv activated while I can just launch it by accessing the directory and type flask run in cmd, would appreciate any answers.
ss of the project's directory
ss of venv/Scripts/
ss of bash screen with errors
The error message suggests that the requirements.txt file can't be read. Check that you definitely can read it and it's in the expected location.
The perferred command for running pip is:
python3 -m pip install -r requirements.txt
This makes sure that you know which python3 binary you're running pip with - some systems have more than one python3 binary in various locations.
You could achieve similar without activating the virtual environment:
./venv/bin/python3 -m pip install -r requirements.txt
I am trying to run below commands but it's not working on my windows machine.
C:\Users\XXX\Desktop\python-7>pip install chalice -t .
ERROR: Can not combine '--user' and '--target'
C:\Users\XXX\Desktop\python-7>pip install --user --install-option="--prefix=" chalice -t .
ERROR: Can not combine '--user' and '--target'
Can someone please let me know if there is any alternative to get the module in the same directory ?
UPDATE
C:\Users\XXX\Desktop\python-7>pip install --target=C:\Users\XXX\Desktop\python-7 chalice
ERROR: Can not combine '--user' and '--target'
add --no-user at the end of the command and it should work
This happens with the Python version distributed on the Windows AppStore.
I believe it's because that version installs the basic executables under C:\Program Files\WindowsApps, a secured location that users cannot modify; pip is then aliased to actually run as something like pip --user C:\Users\<your_user>\AppData\Local\Packages\PythonSoftwareFoundation.Python.<version>_<id>\LocalCache\local-packages\Python<version>, so users will install packages to a writeable folder.
Hence, as soon as you try to add --target, pip breaks.
You can simply use:
C:\Users\XXX\Desktop\python-7>pip install chalice
I tried to follow the documentation and got stuck in the point
Open a terminal and follow the instructions to configure a new Python virtual environment and install the `google-assistant-library.
The link in this point redirects to a general page (Introduction to the Google Assistant Library) rather than the instructions.
I think it misses the explanation what it means to open the terminal and exact steps to be followed.
Is the link really correct?
Maybe I need help in using the console correctly, but I am not getting it from that poor documentation.
I can connect to RP with Serial to USB cable and Putty. But simply I do not know what that point 11 and onwards mean...
Any idea?
Thank you
It looks like the links in the Assistant SDK docs were modified, but it should be pointing to this page:
sudo apt-get update
sudo apt-get install python3-dev python3-venv # Use python3.4-venv if the package cannot be found.
python3 -m venv env
env/bin/python -m pip install --upgrade pip setuptools
source env/bin/activate
python -m pip install --upgrade google-auth-oauthlib[tool]
google-oauthlib-tool --scope https://www.googleapis.com/auth/assistant-sdk-prototype \
--save --headless --client-secrets /path/to/client_secret_client-id.json
This will save the credentials at /path/to/.config/google-oauthlib-tool/credentials.json, which you can then copy into your project in order to authenticate the Google Assistant.
As Nick and proppy noted, one step is to obtain authorization code to be used in later steps. Unfortunately the documentation skipped few very important steps and it can lead to confusion. Sadly Google did not simplify the process of integrating the Assistant in the same development environment and hope they will integrate this clumsy process to Android Studio as with other services
If you are developing under Windows you need to:
use a Linux environment and follow the steps in console of that Linux PC (not in the Android Things console of the RP!). Or install Python in Windows. I used the Raspbian in my RP3 to do the Linux version of the procedure...
install Python environment first in the Linux PC console
sudo apt-get update
sudo apt-get install python3-dev python3-venv
python3 -m venv env
env/bin/python -m pip install --upgrade pip setuptools
source env/bin/activate
in this Python environment install google-auth-oauthlib that will generate the credential file
python -m pip install --upgrade google-auth-oauthlib[tool]
change the directory to place you saved the downloaded json file from step before step 11 in the documenatation. e.g.
cd /home/pi/Downloads/
run the google auth tool with the path to your downloaded json file (including its long name, replace idxxx with your id)
google-oauthlib-tool --client-secrets /home/pi/Downloads/client_secret_client-idxxx.json --scope https://www.googleapis.com/auth/assistant-sdk-prototype --save --headless
there will be a link generated in the console. You have to insert the link into browser . You will be prompted in browser to let the tool to use your account and the you will receive an authentication code. Enter this code to the prompt back in the console.
find the generated authenticated authorization code file in the folder prompted in the console and continue in the original documentation steps
I was trying to install the postgres through terminal on mac os. I used homebrew to install the postgres.
During the install I got following error
"Error: The brew link step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/man/man3/SPI_connect.3"
I also got error regarding initdb
"initdb: file "/usr/local/share/postgresql/postgres.bki" does not exist
This might mean you have a corrupted installation or identified
the wrong directory with the invocation option -L.
Warning: The post-install step did not complete successfully
You can try again using brew postinstall postgresql"
After the install I am not able to run any of postgres commands. I would really appreciate any help as I am new to postgres. Please, provide little explanation.
Thank You!
Not sure if this solution is the best, but so far this is the only one.
Note: I did this on a macOS environment
I have chowned the directory I wasn't allowed to write. (chown -R user/usr/local/lib/pkgconfig)
/usr/local/lib/pkgconfig` (assumed that dir should be mine anyway - since it's within /usr/local)
I ran
brew link postgres - so the links required are there
Then initdb /usr/local/var/postgres -E utf8 worked perfectly.
Running brew postinstall postgres --debug gives:
Errno::EACCES: Permission denied # dir_s_mkdir - /usr/local/var/postgres
Creating the directory manually and setting the right group worked:
cd /usr/local/var
sudo mkdir postgres
sudo chown <user> postgres
sudo chgrp admin postgres/
I recently ran the following command to install the Amazon Elastic Beanstalk Command Line Interface (EB CLI). I would now like to remove it from my Windows 10 machine.
C:\Users\Cale>pip install --upgrade --user awsebcli
What is the best command to run to ensure that its fully removed from my machine?
I was able to uninstall using the following command:
C:\Users\Cale>pip uninstall awsebcli
I was uncertain how to do the uninstall since I specified --user in the original install command. This stackoverflow article helped me understand that the --user option would not matter during the uninstall process.
How to uninstall a package installed with pip install --user
For me, the awsebcli is not present in the pip list command that references the $PATH. I get this error:
Skipping awsebcli as it is not installed.
Apparently, it's on the pip executable(s) in this location (Windows, PowerShell format):
$env:userprofile\.ebcli-virtual-env\Scripts\
The uninstall command worked properly using one of those executables.
After that, it it seems that deleting the .ebcli-virtual-env will remove it fully from the machine: How do I remove/delete a virtualenv? (disclaimer: I'm not a pythonista :) )
