问题
I've been following a guide in how to install Miniconda3 and use that to install different packages as NumPy and SciPy.
However, after installing Miniconda3 and opened a new project in PyCharm, the guide tells me that I should write:
conda install numpy
...which returned:
Fetching package metadata: Could not connect to https://repo.continuum.io/pkgs/free/noarch/
Could not connect to https://repo.continuum.io/pkgs/pro/win-32/
Could not connect to https://repo.continuum.io/pkgs/free/win-32/
.Could not connect to https://repo.continuum.io/pkgs/pro/noarch/
...
Error: No packages found in current win-32 channels matching: numpy
You can search for this package on Binstar with
binstar search -t conda numpy
You may need to install the Binstar command line client with
conda install binstar
Which opted me to try:
conda install binstar
...which gave me the same error (even including the last line opting me to try conda install binstar).
I also tried, as a reference, to use conda update conda which resulted in Error: No packages found in current win-32 channels matching: conda.
I've added Miniconda when installing into my PATH variables. Does anybody have any clue regarding this?
EDIT: I have 32 bit system, and I've installed the 32 bit version of Miniconda.
回答1:
It looks like conda is not able to reach the package repository, so you likely have connection issues (your firewall might be blocking conda, or maybe you are behind a proxy).
Here are 3 workaround (if you cannot fix your network problem):
1. Install Anaconda instead of Miniconda
You could install Anaconda from continuum website. Unlike Miniconda, it comes with a lot of pre-installed packages such as numpy and scipy.
2. Install numpy from a pre-built conda archive
You can manually download the archives package from the conda repository, and install them using:
conda install numpy.tar.bz2
You need to download the archive for your operating system. Depending on the package you chose, you may have issue with dependencies...
3. Download pre-built wheel files
This site1 provides tons of pre-built package for Windows, which are relatively easy to install:
python -m pip install numpy.whl
You should use the python executable that comes with conda (should not be an issue if you do not have multiple python installations on your system).
1 I am not the author nor the maintainer of this site, I just find it very useful when you want to install python packages on Windows and cannot use pip/conda.
