错误无法为 xmlsec 构建轮子，这是安装基于 pyproject.toml 的项目所必需的

Question

我尝试在终端的本地模式下安装 Rasa X 时遇到错误。使用 Python 3.7.4 和 pip 版本 21.3.1。使用 Mac.

  Building wheel for xmlsec (pyproject.toml) ... error

  ERROR: Failed building wheel for xmlsec
Failed to build xmlsec
ERROR: Could not build wheels for xmlsec, which is required to install pyproject.toml-based projects

我该如何解决这个问题？

Answer 1

尝试在安装 Rasa X 之前添加： brew install libxml2 libxmlsec1 pkg-config

错误无法为 xmlsec 构建轮子，这是安装基于 pyproject.toml 的项目所必需的

ERROR Could not build wheels for xmlsec, which is required to install pyproject.toml-based projects

xmlsec

python-3.x
