安装visual studio 2019后如何正确激活anaconda环境

Question

安装Visual Studio 2019后，我的anaconda出现问题。当我在我的 anaconda 中创建一个新的环境时，几个小时后我在尝试激活环境时遇到了问题，之后当我打开任何 jupyter notebook 时，内核将无法工作。我在激活环境时复制了消息。如何恢复我的 anaconda 环境？我已经卸载了 Visual Studio 并删除了它的所有文件，但问题仍然存在。感谢您为解决此问题提供的任何帮助。我正在使用 Windows 10 和 Anaconda 3.

Answer 1

通过删除

vs2017_compiler_vars

中的

Anaconda3\envs\enviro\etc\conda\activate.d

文件解决了。

Answer 2

问题是由 conda 包

vswhere

引起的，我相信它是与

vs2017_win-64

一起安装的。

问题仍然悬而未决。见https://github.com/conda/conda/issues/10931

因此，如果您不需要在 conda 环境中集成 Visual Studio，则应卸载具有依赖项的包。

conda uninstall vswhere

但是如果你需要 VS2017，例如像

theano-pymc

这样的编译库的依赖项，那么安装正确的 Visual Studio 或手动调整你的环境变量：

VSINSTALLDIR

等。 要仅删除此详细包，请使用：

conda remove vswhere --force -y
