从以前创建的.yml文件创建conda环境时遇到问题。
运行conda env create -f myenv.yml时出现错误：
Pip subprocess error:
Could not find a version that satisfies the requirement anaconda-tests==0.0.0 (from -r /home/robin/condaenv.m8gm40vv.requirements.txt (line 2)) (from versions: )
No matching distribution found for anaconda-tests==0.0.0 (from -r /home/robin/condaenv.m8gm40vv.requirements.txt (line 2))
You are using pip version 10.0.1, however version 19.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
CondaEnvException: Pip failed
版本：
pip 10.0.1
和
conda 4.6.14
.yml文件看起来正常，并且包括所有pip包。
以前，我曾尝试升级到pip 19.0.1，但是与其他软件包存在很多版本冲突（因为我使用的是python 3.5.2），所以我不得不对其进行降级。
我认为这可能与我使用的conda版本有关，因为该错误与anaconda-tests==0.0.0有关。
从我的.yml文件中删除anaconda-tests==0.0.0后，还有其他相互冲突的软件包，因此我只是删除了它们，或者删除了版本号之后的“ = xxxx”部分。现在，我成功地创建了环境。
作为参考，原始环境（我导出的环境）的输出
