पर्यावरण एकीकरण

$ pre-commit install
pre-commit installed at .git/hooks/pre-commit
$ pre-commit --version
pre-commit 2.4.0

यदि .pre-प्रतिबद्ध sqlite पर शपथ लेगा, तो आपको इसे स्थापित करने की आवश्यकता होगी (उदाहरण के लिए $ yum sqlite स्थापित करें) और फिर से अजगर का निर्माण करें

.Pre-प्रतिबद्ध-config.yaml फ़ाइल सेट करना
