问题描述

我一直在使用VScode在Windows OS上设置所有环境变量的情况下进行抖动处理.现在，我在VScode的Git Bash终端中使用颤振升级"将颤振升级到稳定版本，现在我无法在VScode的Git Bash终端中使用颤振命令.我想知道哪里出了问题，我该如何解决?

I have been working on flutter using VScode with all environment variables set on Windows OS. Now i upgraded the flutter using "flutter upgrade" in Git Bash terminal of VScode to the stable version and now i am not able to use flutter commands in Git Bash terminal of VScode. I wonder where things could have gone wrong , how do i fix it ?

我重新验证了所有环境变量均已根据官方文档正确设置.通过Flutter控制台，Flutter命令也可以完美运行.

I re-verified that all my environment variables are set correctly according to official documentation. Also flutter commands are running perfectly through flutter console .

$ flutter doctor
bash: flutter: command not found

编辑:如Sam所述，对〜/.bash_profile"进行了更改，仍然出现相同的错误.我也重新检查，环境变量已经在那里设置.有什么想法我可以进一步解决吗?提前致谢 :) 同样，当执行步骤3的命令source ~/.bash_profile时，输出为

Edit: Made changes to the "~/.bash_profile" as mentioned by Sam , still getting the same error . Also i re-checked and the environment variables are set there already. Any ideas what i could do further to fix it ? Thanks in Advance :) Also when executed command of step no 3. source ~/.bash_profile , output is

$ source ~/.bash_profile
bash: C:DEVLOPMENTflutterbin: command not found
bash: C:DEVLOPMENTflutterbincachedart-sdkbin: command not found```

推荐答案

以前设置的环境变量可能在某个时候被清除了，这就是为什么Flutter命令无法被识别的原因.

It's possible that the environment variable, that was previously set, got cleared at some point and that's why the Flutter command is not recognized.

无论如何，要确保Flutter位于您的配置文件中，一种方法是将其添加到~/.bash_profile(bash配置文件)文件中的路径中. ~/.bash_profile是每次打开Git Bash时都会执行的脚本.

In any case, one way to make sure that Flutter is in your profile is to add it to your path within your ~/.bash_profile (bash profile) file. The ~/.bash_profile is a script gets executed every time you open Git Bash.

向您的Bash个人资料添加Flutter

1. 打开您的~/.bash_profile文件进行

1. Open your ~/.bash_profile file for editing:

$ nano ~/.bash_profile

1. 将以下行添加到~/.bash_profile文件的顶部:

1. Add to the top of your ~/.bash_profile file, the following lines:

# Add Flutter to PATH
PATH=/path/to/flutter/bin:$PATH

# Add Dart to PATH
PATH=/path/to/flutter/bin/cache/dart-sdk/bin:$PATH

用Flutter安装目录的绝对路径替换/path/to/flutter.

1. 应用更改:

$ source ~/.bash_profile

确保为非登录外壳打开Git Bash
