安装后Heroku CLI命令无法识别

Question

我安装了Heroku CLI和git。安装后，我重新启动了命令提示符。当我运行git命令时，那些被认可很好。但是，当我输入Heroku命令（例如heroku version）时，它们无法识别。

所以我设置路径变量指向Heroku安装。现在，Heroku命令正在工作，但git命令已变得无法识别。

实际问题是什么？

这里是cmd提示内容。

Answer 1

set path="C:\Program Files\Heroku\bin" 

通过这样做，你更换 PATH变量以只包含路径。所以你基本上打破了一切。

你通常做的是在PATH变量的后面添加或预先加入新路径，例如，像这样：

set PATH=%PATH%;C:\Program Files\Heroku\bin 

永久的解决方案是编辑你的Windows默认包含到Heroku可执行文件的路径。在超级用户上看到这个问题的更多信息和说明：What are PATH and other environment variables, and how can I set or use them?
