Anaconda - UnsatisfiableError: The following specifications were found to be in conflict
提问by qismees
When I was trying to install a module 'pymc' through anaconda environments, it showed the error message as follows:
当我尝试通过 anaconda 环境安装模块“pymc”时，它显示如下错误消息：
UnsatisfiableError: The following specifications were found to be in conflict:
blaze -> pyyaml -> python[version='>=2.7,<2.8.0a0'] -> vc=9
blaze -> pyyaml -> yaml -> *[track_features=vc9]
pymc Use "conda info " to see the dependencies for each package.
UnsatisfiableError：发现以下规范存在冲突：
火焰 -> pyyaml -> python[version='>=2.7,<2.8.0a0'] -> vc=9
火焰 -> pyyaml -> yaml -> *[track_features=vc9]
pymc 使用“conda info”查看每个包的依赖关系。
I am using Python 2.7.14, and I installed anaconda 1.6.9 on a Windows. I am new to Python. I first tried to use cmd to install the module pymc and I ran into a lot of problems such as the requirement for install g77 compiler on windows. After I got the compiler from MinGW and also installed the Microsoft Visual C++ Compiler for Python, I still cannot install the module because there came new errors. That is when I found there is pymc module listed in anaconda environment that I can add manually, but it showed this conflict error.
我使用的是 Python 2.7.14，我在 Windows 上安装了 anaconda 1.6.9。我是 Python 的新手。我首先尝试使用cmd安装模块pymc，但遇到了很多问题，例如要求在windows上安装g77编译器。在我从 MinGW 获得编译器并安装了 Microsoft Visual C++ Compiler for Python 后，我仍然无法安装该模块，因为出现了新错误。那时我发现在 anaconda 环境中列出了 pymc 模块，我可以手动添加，但它显示了这个冲突错误。
I do not know whether the conflict comes from all those other stuff I installed above or not. Please HELP! Thanks!
我不知道冲突是否来自我上面安装的所有其他东西。请帮忙！谢谢！

Create a new conda environment for Python 2.7:
为 Python 2.7 创建一个新的 conda 环境：
conda create -n my_pymc_env python=2.7
Activate it:
激活它：
conda activate my_pymc_env
Alternatively, for older conda versions on Windows:
或者，对于 Windows 上的旧版 conda：
activate my_pymc_env
on Unix (including Mac OS X):
在 Unix（包括 Mac OS X）上：
source activate my_pymc_env
Once activated, install your packages:
激活后，安装您的软件包：
conda install pymc blaze
If you still get this message, install the Anaconda client:
如果您仍然收到此消息，请安装 Anaconda 客户端：
conda install anaconda-client
and search for your package:
并搜索您的包裹：
anaconda search mypackage
Look for a channel that has the right version for you and install:
寻找适合您的频道并安装：
conda install -c channel_with_right_version mypackage
