尝试在Windows 10和Anaconda上安装PyInstaller

Question

我正在尝试在Windows 10上使用Anaconda 2018.12的Python 3.7安装PyInstaller

我输入了： conda install -c conda-forge pyinstaller并收到以下错误消息：

Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - anaconda==2018.12=py37_0
  - pyinstaller
Use "conda info <package>" to see the dependencies for each package.

然后，我键入conda info pyinstaller但没有特殊输出。 我也用pyinstaller=3.2.1而不是pyinstaller做了同样的pyinstaller但这并没有改变任何东西

我该怎么办？
