Question

我最近尝试在Windows上安装Minicoda3。我从Windows命令提示符下创建了正确的环境变量，并以管理员身份通过anacoda提示符检查了我的python能否正常运行。命令print（“ Hello”）有效。

回到Windows命令提示符时，键入 conda update conda ，然后出现以下错误：

TypeError：LoadLibrary（）参数1必须为str，而不是None

更具体地，我的提示如下：

我尝试卸载并重新安装miniconda，但它不起作用。我需要Miniconda才能安装其他软件。我还观看了一段有关在conda上创建和激活新（空？）环境的视频，但我不明白该建议的用处。另一个可能有用的问题是，在Windows cmd上询问python时，我得到了：

Python 3.7.3 (default, Apr 24 2019, 15:29:51) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32

由于错误而发生此错误。幸运的是，Anaconda团队很可能会在今年内发送更新以解决此问题。直到您可以尝试使用此命令来避免此问题。

conda update python-libarchive-c

Miniconda3更新错误：TypeError：LoadLibrary（）参数1必须为str，而不是None
