python - 在 virtualenv 中使用 pip install 时出现 UnicodeDecodeError

Question

我正在虚拟环境中安装 Nucypher 并收到 UnicodeDecodeError ，如下所示:

命令:

python -m pip install nucypher

输出:

ERROR: Exception:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 185: invalid continuation byte

我使用的是 Windows 10，pip 19.1.1。 在同一虚拟环境中安装 Numpy 时，我没有收到此错误。请建议需要做什么。提前致谢!

我刚刚从 Mac 迁移到 Windows，在使用 PowerShell 和 virtualenv 时遇到了完全相同的问题。我已转而使用命令行，而不是使用内置的 venv，并且它有效。如果您不固定使用 virtualenv，那么可能值得一试。
