问题 I am wondering if it's possible to install npm packages directly through conda's environment.yml file. I know one can install pypi packages with pip directly as follows: name: docs channels: - conda-forge dependencies: - python>=3.7 - nodejs=10.* - pip - pip: - Sphinx==1.6.5 I've tried adding npm as a dependency as it's installed via nodejs but that doesn't work, unfortunately. name: docs channels: - conda-forge dependencies: - python>=3.7 - nodejs=10.* - pip - pip: - Sphinx==1.6.5 - npm: -

How can I make npm to resolve dependencies across different folders? Service_A and Service_B are local modules I had preloaded inside node
