Java Cassandra 3.11.6未启动Windows 10
我是卡桑德拉的新手,我正在使用Windows10进行开发。但这次卡桑德拉在浪费我的时间。我已经阅读了文档,但仍然有相同的问题 我的步骤如下:Java Cassandra 3.11.6未启动Windows 10,java,cassandra,cassandra-3.0,Java,Cassandra,Cassandra 3.0,我是卡桑德拉的新手,我正在使用Windows10进行开发。但这次卡桑德拉在浪费我的时间。我已经阅读了文档,但仍然有相同的问题 我的步骤如下: Windows 10 64位 已安装Java jdk-14.0.1 把爪哇放在家里 已安装的Cassandra-3.11.3 安装了Python 设置必要的环境变量 在PowerShell中将当前用户的执行策略设置为不受限制的 然后在Cassandra\bin文件夹中运行Cassandra.bat 但它显示了以下错误: PS C:\Program File

中将当前用户的执行策略设置为不受限制的
Cassandra\bin
文件夹中运行Cassandra.bat
PS C:\Program Files\apache-cassandra-3.11.6\bin> .\cassandra.bat -f
检测到powershell执行权限。使用增强的启动脚本运行
