python - 无法在 Pycharm 中创建或导入现有的 conda 项目

Question

我正在尝试在 PyCharm 中创建或打开现有的 conda 项目。在这两种情况下，我都会收到此错误:

TypeError: LoadLibrary() argument 1 must be str, not None

我在我的 Windows 机器上安装了 Anaconda3 软件包 (conda 4.7.5)。我能够从 Anaconda Prompt 成功使用它(创建和使用环境、安装包和创建项目)。但是每次我尝试通过使用 Python 3.6 选择“文件 -> 新项目 -> 科学 -> 使用 Conda 的新环境”在 PyCharm 中创建项目时，我都会在创建项目时遇到上述错误。

或者，当我在 PyCharm 中打开现有的 conda 项目(来自 Anaconda Prompt)，然后尝试选择 conda 作为解释器时，我遇到了完全相同的错误。

我已经尝试解决这个问题 3 个小时了:阅读论坛、安装旧版本、尝试使用 miniconda。这是 PyCharm 的问题吗？

编辑:附加的完整堆栈跟踪。

我在通过命令提示符创建 conda 环境时遇到了同样的问题。我在我的环境变量中添加了它。这对我有帮助。也许它也能帮到你
