【问题描述】:
我正在尝试在我的 Mac 上更新 anaconda。当我运行命令conda update anaconda 时,我得到以下输出
The following packages will be downloaded:
package | build
---------------------------|-----------------
conda-env-2.6.0 | 0 601 B
conda-4.2.13 | py27_0 375 KB
------------------------------------------------------------
Total: 375 KB
The following packages will be SUPERCEDED by a higher-priority channel:
conda: 4.2.13-py27_0 conda-forge --> 4.2.13-py27_0
conda-env: 2.6.0-0 conda-forge --> 2.6.0-0
hdf5: 1.8.17-8 conda-forge --> 1.8.15.1-1
jpeg: 9b-0 conda-forge --> 8d-1
libpng: 1.6.26-0 conda-forge --> 1.6.17-0
libtiff: 4.0.6-5 conda-forge --> 4.0.2-1
numexpr: 2.6.1-np111py27_0 conda-forge --> 2.4.3-np19py27_0
The following packages will be DOWNGRADED due to dependency conflicts:
numpy: 1.11.0-py27_0 --> 1.9.2-py27_0
pip: 8.1.2-py27_0 --> 7.0.3-py27_0
scikit-learn: 0.17.1-np111py27_0 --> 0.16.1-np19py27_0
scipy: 0.17.0-np111py27_0 --> 0.15.1-np19py27_0
Proceed ([y]/n)?
我的问题是为什么包会是DOWNGRADED?或者是否有任何更好的方法可以使系统保持最新状态。

当我执行conda update --all 时,我得到以下输出:
Fetching package metadata .......
Solving package specifications: ....
UnsatisfiableError: The following specifications were found to be in conflict:
- jasper -> jpeg 9*
- sockjs-tornado
Use "conda info <package>" to see the dependencies for each package.
