我已经安装了Anaconda以便日常使用。最近，我安装了也支持python的商业软件。该软件将miniconda安装在另一个文件夹中，并为其创建了一个环境。但是，当我激活环境并使用conda或'pip'安装一些软件包时，发生了错误。
例如，conda install scipy导致：

pip install scipy引起的原因：

有人知道如何解决此问题吗？
答案 0 :(得分：0)
您应该先安装ruamel.yaml
pip install ruamel.yaml
答案 1 :(得分：0)
最后我解决了...事实证明，当软件Gatan GM创建环境时，它安装了conda的某些版本。这是软件使用的命令：
C:\ProgramData\miniconda3\scripts\conda create --prefix C:\ProgramData\miniconda3\envs\GMS_VENV_PYTHON1 --offline --yes python-3.7.1-h8c8aaf0_6.tar.bz2 ca-certificates-2019.10.16-0.tar.bz2 openssl-1.1.1d-he774522_3.tar.bz2 numpy-1.17.1-py37hc71023c_0.tar.bz2 intel-openmp-2019.4-245.tar.bz2 tqdm-4.36.1-py_0.tar.bz2 vs2015_runtime-14.16.27012-hf0eaf9b_0.tar.bz2 libblas-3.8.0-14_mkl.tar.bz2 certifi-2019.9.11-py37_0.tar.bz2 liblapack-3.8.0-14_mkl.tar.bz2 mkl-2019.4-245.tar.bz2 conda-4.7.12-py37_0.tar.bz2 conda-package-handling-1.6.0-py37h62dcd97_0.tar.bz2 libcblas-3.8.0-14_mkl.tar.bz2
删除环境并在没有conda相关软件包的情况下重新创建环境后，问题已解决。
