This section provides a tutorial example to install chembl_webresource_client, the Official Python client for accessing ChEMBL API.

If you are a Python user, you should intall chembl_webresource_client, which is the Official Python client for accessing ChEMBL API.

1. Make sure you have Python installed.

2. Install chembl_webresource_client with "pip" command:

herong$ pip3 install chembl_webresource_client

Collecting chembl_webresource_client

    requests>=2.18.4 (from chembl_webresource_client)
  ERROR: No matching distribution found for requests>=2.18.4

3. Search for the missing package. "request (2019.4.13)" is available.

herong$ pip3 search request

5. Install chembl_webresource_client again:

herong$ pip3 install chembl_webresource_client

Collecting chembl_webresource_client
Collecting urllib3 (from chembl_webresource_client)
Collecting requests>=2.18.4 (from chembl_webresource_client)

6. Install requests-cache first:

herong$ pip3 install requests-cache

Collecting requests-cache
Collecting requests>=1.1.0 (from requests-cache)
Collecting idna<2.9,>=2.5 (from requests>=1.1.0->requests-cache)
Collecting urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1 (from requests...)
Collecting chardet<3.1.0,>=3.0.2 (from requests>=1.1.0->requests-cache)

Successfully installed certifi-2019.11.28 chardet-3.0.4 idna-2.8 \
   requests-2.22.0 requests-cache-0.5.2 urllib3-1.25.7

7. Install chembl_webresource_client for the third time:

herong$ pip3 install chembl_webresource_client
Collecting chembl_webresource_client
Requirement already satisfied: urllib3 in /Library/...
Requirement already satisfied: requests>=2.18.4 in /Library/...

Successfully installed chembl-webresource-client-0.10.0 easydict-1.9

Finally, I have chembl_webresource_client installed. For more information, go to the "Official Python client for accessing ChEMBL API" Website at https://github.com/chembl/chembl_webresource_client.
