我正在使用 python 3.7 并尝试imutils通过以下方式在 conda 中安装软件包：

conda install imutils
conda install -c mlgill imutils=0.5.4
conda install -c conda-forge/label/cf202003 imutils=0.5.4
conda install -c conda-forge imutils

它们都产生相同的错误：

Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - imutils

Current channels:

  - https://repo.continuum.io/pkgs/main/linux-64
  - https://repo.continuum.io/pkgs/main/noarch
  - https://repo.continuum.io/pkgs/free/linux-64
  - https://repo.continuum.io/pkgs/free/noarch
  - https://repo.continuum.io/pkgs/r/linux-64
  - https://repo.continuum.io/pkgs/r/noarch
  - https://repo.continuum.io/pkgs/pro/linux-64
  - https://repo.continuum.io/pkgs/pro/noarch

除非：

conda install -c conda-forge imutils

生成：

InvalidVersionSpecError: Invalid version spec: =2.7

imutils 库是一个非 conda 包。我已经安装了pip

pip install imutils
