I want to Blackfire

which uses

for the language.

To start using Blackfire, we are going to install the following:

A language extension;
An agent to communicate with Blackfire's servers (as you chose a quick install, you will use a shared agent instead of installing one on your machine);
A profiling client (a browser extension or a CLI tool).

Install the Agent ¶

BLACKFIRE_CLIENT_ID="CLIENT_ID" \
BLACKFIRE_CLIENT_TOKEN="CLIENT_TOKEN" \
BLACKFIRE_SERVER_ID="SERVER_ID" \
BLACKFIRE_SERVER_TOKEN="SERVER_TOKEN" \
bash -c "$(curl -L https://installer.blackfire.io/installer.sh)"

This installs the APT package for the Blackfire Agent. It might prompt for your password to grant root privileges.

Install the Python Probe ¶

Install pip:
```
sudo apt install python-pip
```
Install the blackfire package:
```
pip install blackfire --user
```
If you have multiple versions of Python installed on your system, it is possible that you have multiple versions of the pip binary installed as well. For example, you can have pip2 installed for Python >= 2.0, and pip3 installed for Python >= 3.0.
Ensure blackfire-python command is in your $PATH.
Blackfire pip package installs the blackfire-python command, which can be used for zero configuration profiling.

The folder where blackfire-python is installed may vary depending on your Python environment (e.g. pyenv, virtualenv).
Note that the folder blackfire-python is installed in must be in your $PATH.
If you previously installed Blackfire bootstrap configuration hook (blackfire_bootstrap.pth, in versions <= 1.4.5), you must uninstall it by running the following command:
```
python -m blackfire uninstall-bootstrap
```
