如果我做

我可以看到所有可用的软件包。

我pandas今天早上更新到最新版本，但我现在需要恢复到以前的版本。我试过了

但这没有用。如何指定要使用的版本？

我已经使用 conda build 成功构建了 fftw 和 pyfftw 的包。我现在正在尝试编写一个 run_test.py 例程来执行 pyfftw 中的测试，作为构建过程的一部分。我写了一个 run_test.py 来运行 pyfftw 中的一个测试文件：

在构建结束时，我收到以下错误：

我是否将文件添加到包中？或者也许将文件复制到测试环境？我实际上不知道如何进行。任何帮助，将不胜感激。

我尝试使用最新版本的conda和 Anaconda安装最新版本的GData：

康达安装 gdata

它似乎奏效了。

但是，当我尝试这样做时：

我得到：

为什么？我该如何使用它？

I'm using conda to run tests against different versions of python, numpy, etc., but there are some common dependencies for all combinations of python/numpy. Is there a way to install such packages into all conda environments, or do I have to specify each by hand?

我想使用 conda 创建不同的环境，每个环境都有不同的 $PYTHONPATH。目前，我每次都必须在我的 .bashrc 中更改环境变量。是否有一种通过 conda 创建多个 python 环境的简单方法，以便我可以无缝切换（通过源激活）并自动更新相应的 $PYTHONPATHs？

I recently switched to the Anaconda Python distribution and I'm trying to get the hang of things. I wanted to install this yaml-related package and since there isn't already a conda recipe for it, I tried

which resulted in the following output (I removed non-relevant entries of my system path):

I'm not sure what happened since I don't know what file it was looking for and I don't yet know anything about conda recipes except they're supposed to be awesome and not give these kinda of errors.

I was hoping to install through conda so that everything could be managed by conda instead of some stuff being managed by pip.

Digging into the main_pipbuild.py source it looks like it's trying to run C:\Anaconda\envs\_pipbuild_\bin\pip install package==version (with the appropriate package and version). When I look at my C:\Anaconda\envs_pipbuild_ there is no bin folder, so I'm guessing pip didn't get installed into the pipbuild environment correctly. The previous warnings about not having "patch" may also be a problem...

After installing patch with conda install patch I tried again with the following results:

So it finds some kind of problem with the package perhaps at Solving package specifications: .69 unparsed bytes left at the end of stream. Then it does this patch thing which apparently fails. Then it tries to do pip install and again can't find the bin/pip directory in the pipbuild environment.

Should it be looking for pip at C:\Anaconda\envs\_pipbuild_\Scripts\pip.exe? Because that does exist.

If this is a bug, here's where to report it: https://github.com/conda/conda-build/issues. I'll wait for feedback before doing any more.

Any help would be great!

我有一个 python 2.7 conda 环境，想用 python 3.4 创建一个等效的环境。我--clone在创建环境时知道该选项，但它不接受其他参数，例如python=3.4. 有没有办法自动做到这一点？我考虑过尝试使用 的输出conda list --export，但这也对 python 版本进行了编码。

I am setting up calls to python (Anaconda distribution) via BAT files and the windows task scheduler.

I've now used environments for the first time and was trying to set a .bat file up as below:

Unfortunately it appears that the second command does not get executed.

我正在努力让 Tox 和 Conda 一起玩得很好。主要是因为我有很多非 python 依赖项需要安装，而且很容易创建 Conda 发行版。然后我可以用一个简单的conda install.

但是，我无法激活 conda 环境。

python build_env.py --conda-env {toxworkdir}/conda {packages}负责创建环境（如果需要）、安装软件包等。问题就在于此source activate {toxworkdir}/conda。我得到一个ERROR: InvocationError: could not find executable 'source'错误。直接在命令行中输入命令可以正常工作。

对于那些有兴趣的人。在build_env.py这个要点中：https ://gist.github.com/JudoWill/70450979353fa2d12823 ...目前它只是安装 Python 依赖项，但在其预期的环境中它将安装不一定是 Python 库的 Conda 存储库。有什么想法吗？

我在 Mac OS 10.9.4 (Maverick) 上运行 Python 2.7.8 :: Anaconda 2.0.1 (x86_64) 和 conda 3.5.5

我通过运行安装了 PyMC

conda install -c https://conda.binstar.org/pymc pymc

但是，import pymc给出了一个错误（我在最后复制了 Traceback）。

Edit1：通过阅读这个问题"cannot import name flib"，在我看来，问题在于通过使用 anaconda 安装 PyMC，它是针对不同的 gfortran 构建的，而不是由brew install gcc. 我很乐意卸载并重试，但我希望在我把事情搞砸之前，有人会给我提供指导！

Edit2： Traceback 告诉我//anaconda/lib/python2.7/site-packages/pymc/flib.so正在尝试调用/usr/local/Cellar/gfortran/4.8.2/gfortran/lib/libgfortran.3.dylib，它不存在。我认为直到最近才homebrew自行安装 gfortran，因此在/usr/local/Cellar. 但是，现在gfortran是/usr/local/Cellar/gcc/4.8.3_1/bin由brew install gcc. 帮助！

（旁白：由于该错误表明我安装的 gfortran 编译器存在问题，因此brew让我为您提供一些详细信息，尽管可能不相关。

我gfortran通过调用从 brew安装

brew install gcc

它抛出了一些错误，并建议我链接 gmp、mpfr、libmpc、isl 和 cloog。因此我做到了

brew link gmp（和mpfr等）

以防万一，which gfortran给

/usr/local/bin/gfortran

这是回溯import pymc：
