今天pip安装一直遇到Jinja2冲突
可以使用pipdeptree定位冲突原因
说明文档
https://pypi.org/project/pipdeptree/
pipdeptree -r -p Jinja2
Warning!!! Possibly conflicting dependencies found: * Flask==2.0.0 - Jinja2 [required: >=3.0, installed: 2.11.3] * networkx==2.5.1 - decorator [required: >=4.3,<5, installed: 5.0.9] * pytest-cov==2.12.0 - pytest [required: >=4.6, installed: 3.7.0] ------------------------------------------------------------------------ Jinja2==2.11.3 - Flask==2.0.0 [requires: Jinja2>=3.0] - flasgger==0.9.5 [requires: Flask>=0.10] - Flask-Cors==3.0.10 [requires: Flask>=0.9] - Flask-Limiter==1.4 [requires: Flask>=0.8] - Flask-Login==0.5.0 [requires: Flask] - Flask-Migrate==3.0.0 [requires: Flask>=0.9] - Flask-Script==2.0.7 [requires: Flask] - Flask-SQLAlchemy==2.5.1 [requires: Flask>=0.10] - Flask-Migrate==3.0.0 [requires: Flask-SQLAlchemy>=1.0] - pytest-flask==0.15.1 [requires: Flask] - Sphinx==4.0.1 [requires: Jinja2>=2.3,<3.0] - sphinx-rtd-theme==0.5.2 [requires: sphinx] - sphinxcontrib-httpdomain==1.7.0 [requires: Sphinx>=1.5]
从上面可以清晰看到,Flask2要求Jinja2>=3.0,但Sphinx4.0.1要求Jinja2<3.0
