解压到了C盘

没打算设置环境变量

右键点击开始 或 win+x

以管理员身份打开 PowerShell

进入到安装目录下的 bin 目录

可以输入cd 后， 拖动 bin 文件夹到控制台， 一般会自动变成路径

也可以用“资源管理器”进入bin 文件夹， 然后点左上的”文件“ ， 鼠标移到”打开 Windows PowerShell“， 然后点击”以管理员身份打开 Windows PowerShell“

除了 PowerShell，也测试了 CMD ， 发现一些不同

• CMD的路径只能用 \, 不能用 /, PowerShell两者都可以

• 在没配置环境变量路径的情况下， CMD可以直接运行本路径下的x.exe文件，PowerShell要加./
./mysqld或.\mysqld

• 当缺少 VCRUNTIME140_1.dll 时， CMD会弹窗， PowerShell不会弹窗，没有任何提示

此时系统缺少 VCRUNTIME140_1.dll ， CMD执行··

解决 VCRUNTIME140_1.dll 的方法
