Question

我在powershell（Windows）中使用命令'pip install tables'来安装Pytables。但我收到了ValueError: [u'path']。红色写成'Command "python setup.py egg_info" failed with error code 1'。我安装了miniconda。

编辑：完整的红色错误消息如下：

'Command "python setup.py egg_info" failed with error code 1 in c:\users\evert\appdata\local\temp\pip-build-9wkucl\tables
\'

在我的pip install命令和红色错误消息之间写入以下内容：

Collecting tables
  Using cached tables-3.2.2.tar.gz
    Complete output from command python setup.py egg_info:

        raise ValueError(str(list(result.keys())))
    ValueError: [u'path']

缺少哪一部分？在运行'pip install tables'之前，我应该执行哪些步骤？谢谢你的帮助。

Answer 1

这是一个无法使用vcvarsall.bat正确设置设置所需的某些环境变量的问题。您可以下载pytables here的二进制文件，然后执行pip install tables-3.2.2-*.whl。请务必下载与您的版本和系统架构相匹配的二进制文件。

Python，安装Pytables：ValueError：[u'path']
