我刚刚在一台新计算机上安装了 pyzo 和 miniconda。当我尝试从 pyzo 控制台使用 conda 安装(或更新)软件包时,它实际上并没有安装任何东西。我得到这样的东西:
>Python 3.5.2 |Continuum Analytics, Inc.| (default, Jul 5 2016, 11:41:13) on Windows (64 bits).
This is the Pyzo interpreter with integrated event loop for TK.
Type 'help' for help, type '?' for a list of *magic* commands.
>>> conda update --all

Package plan for installation in environment c:\program files\miniconda3:
The following packages will be downloaded:
package | build
---------------------------|-----------------
requests-2.12.4 | py35_0 791 KB
pip-9.0.1 | py35_1 1.7 MB
conda-4.2.13 | py35_0 449 KB
------------------------------------------------------------
Total: 2.9 MB
The following packages will be UPDATED:
conda: 4.2.12-py35_0 --> 4.2.13-py35_0 (copy)
pip: 8.1.2-py35_0 --> 9.0.1-py35_1 (copy)
requests: 2.11.1-py35_0 --> 2.12.4-py35_0 (copy)
但这些软件包实际上并没有更新。当我从 dos 提示符(具有管理员权限)运行“python -m conda update --all”时,我可以让它工作。在这种情况下,我会得到“Proceed ([y]/n)?y”并且可以继续。我认为这应该能够从 pyzo 控制台正常运行,我错了吗?
