无法运行 Spyder，因为没有名为“PySide”的模块

Question

我想尝试使用 Spyder IDE。我正在阅读有关如何打开和运行 Spyder 的页面：https : //github.com/spyder-ide/spyder/releases

我输入了页面中指定的以下命令：

conda update qt pyqt
conda update spyder

两个命令都给出了“#所有请求的包已经安装。”。

然后我在我的终端（Mac）中输入 spyder：

Macs-MacBook:~ macuser$ spyder
Traceback (most recent call last):
  File "/anaconda3/lib/python3.6/site-packages/qtpy/__init__.py", line 166, in <module>
    from PySide import __version__ as PYSIDE_VERSION  # analysis:ignore
ModuleNotFoundError: No module named 'PySide'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/anaconda3/bin/spyder", line 11, in <module>
    sys.exit(main())
  File "/anaconda3/lib/python3.6/site-packages/spyder/app/start.py", line 159, in main
    from spyder.app import mainwindow
  File "/anaconda3/lib/python3.6/site-packages/spyder/app/mainwindow.py", line 49, in <module>

所以，我尝试安装 PySide：

Macs-MacBook:~ macuser$ conda install PySide
Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - anaconda==5.2.0=py36_3
  - pyside
Use "conda info <package>" to see the dependencies for each package.

我应该怎么做才能启动并运行 Spyder？

Answer 1

尝试以下命令让我知道它是否有效。

 pip install msgpack
 conda install qt=5.6 pyqt=5.6 sip=4.18
