Recently I updated Mac OS to latest Catalina. Now when entering a flutter command like the following,

最近，我把Mac OS更新到了最新的Catalina。现在，当输入如下所示的颤动命令时，

flutter --version

my terminal (which is using zsh) shows me following error:

我的终端(使用zsh)显示以下错误：

zsh: command not found: flutter

How do I reinstate the path to allow flutter commands from any directory?

如何恢复路径以允许来自任何目录的颤振命令？

优秀答案推荐

You need to update the environment path.

您需要更新环境路径。

1. Open terminal.

   
   



2. vim $HOME/.zshrc

   
   



3. Press "I" key for going to insert mode.

   
   



4. add the following line in the opened file:

   
   

   export PATH="$PATH:/YOUR_FLUTTER_DIR/flutter/bin"

   
   



5. Press "Esc" then write :wq! in terminal and press enter to exit vim.

   
   



6. Reopen the terminal and check "flutter doctor"

   
   

If this solution did not work, remove the double quote from path or use the full path explicitly instead of ~.

如果此解决方案不起作用，请删除PATH中的双引号或显式使用完整路径而不是~。

Working on macOS Catalina 10.15.5 (19F101).
I have used .zprofile instead of .zhrc

使用MacOS Catalina 10.15.5(19F101)。我使用的是.zprofile，而不是.zhrc

1. Provide Full Disk Access to Terminal by
   Setting -> Security & Privacy -> Full Disk Access. Add Terminal

   
   



2. If the current terminal uses bash, change to zshell using the below command

   
   

   chsh -s /bin/zsh

   
   



3. In the root directory i.e something like /Users/^YourAccount^ execute the below

   
   

   touch .zprofile

   
   

   vim .zprofile

   
   



4. Press I to enter insert mode. Type the below

   
   

   export PATH=$PATH:/Users/^YourAccount^/^YourPath^/flutter/bin

   
   



5. Save and quit by pressing Esc, then :wq and Enter

   
   



6. Close Terminal and reopen Again. Then try executing flutter command

   
   

For me removing double quotes did the fix.

对我来说，去掉双引号解决了问题。

Try changing

尝试更改

export PATH="$PATH:[PATH TO FLUTTER]/flutter/bin"

into

vt.进入，进入

export PATH=$PATH:[PATH TO FLUTTER]/flutter/bin

adding few more steps for easiness:

增加了几个简单的步骤：

Open terminal.

开放终端。

vim $HOME/.zshrc

Press "I" to open insert mode.

按“I”打开插入模式。

add the following line in the opened file:

在打开的文件中添加以下行：

export PATH=$PATH:[PATH TO FLUTTER]/flutter/bin (remember I don't have double quotes here)

Press "Esc" then type :wq in terminal to exit edit mode.

按“Esc”键，然后在终端中键入：wq退出编辑模式。

Type
source .zshrc to reload the terminal for changes

键入Source.zshc以重新加载终端以进行更改

You must update your environment $PATH variable.

您必须更新环境$PATH变量。

1) Open the file $HOME/.zshrc $HOME is your home path

1)打开文件$HOME/.zshc$HOME是您的主路径

2) add the following line in the opened file:

2)在打开的文件中添加以下行：

export PATH="$PATH:/YOUR_FLUTTER_DIR/flutter/bin"

3) save the changes and restart your terminal session.

3)保存更改并重新启动终端会话。

The process is also documented here

此处还记录了该过程

Follow these steps:

请执行以下步骤：

Open finder
Enter Cmd + Shift + G

打开查找器输入Cmd+Shift+G

Type ~ in Go to the folder popup.

在弹出的文件夹中键入~。

Now enter Cmd + Shift + . to show hidden files.

现在输入Cmd+Shift+。要显示隐藏文件，请执行以下操作。

Open .zshrc

打开.zshc

Add this line

添加此行

export PATH="$PATH:/YOUR_FLUTTER_DIR/flutter/bin"

Replace this /YOUR_FLUTTER_DIR with the path to your flutter directory.
In my mac, the path is

将此/YOUR_FUTTH_DIR替换为颤振目录的路径。在我的Mac上，路径是

export PATH=$PATH:$HOME/FlutterDevelopment/flutter/bin

in android studio terminal, simply just type this command:

在Android演播室终端，只需输入以下命令：

export PATH="/YOUR_FLUTTER_DIR/flutter/bin:$PATH"

change YOUR_FLUTTER_DIR to your actual directory

将YOUR_FLATTER_DIR更改为实际目录

I updated from Mojave to Catalina and running Terminal, switched to the default/preferred zsh shell, from the bash shell.
Then was hit with

我从Mojave更新到Catalina，并运行终端，从bash外壳切换到默认/首选的zsh外壳。然后被打了一顿

zsh: command not found: flutter

so, followed the advice seen elsewhere to only add the following to Users/MyUserId/.zshrc

因此，按照在别处看到的建议，只将以下内容添加到USERS/MyUserID/.zshc

export PATH="$PATH:/YOUR_FLUTTER_DIR/flutter/bin"

echo $PATH showed that /Users/MyUserId/flutter/bin was now one of the configured PATHs.
However, I couldn't get "flutter doctor" to work but came across a post on jelliesgame.com which suggested copying

ECHO$PATH显示，/USERS/MyUserID/Ffltter/bin现在是配置的路径之一。然而，我没能让《扑翼医生》去上班，但我在jelliesgame.com上看到了一篇帖子，建议我抄袭

Users/MyUserId/.bash_profile to Users/MyUserId/.zshenv

USERS/MyUserID/.bash_PROFILE TO USERS/MyUserID/.zshenv

Now, flutter doctor gives a clean bill of health

现在，扑动医生给出了一份干净的健康证明

This worked for me:

这对我来说很管用：

Steps:

步骤：

1. Type on the terminal:
   

   open .zshrc (This opens the document in text edit)
   

   
   


2. Add this to the end of the file:
   

   export PATH="/Users/YOUR_USERNAME/Documents/code/tools/flutter/bin:$PATH"
   

   
   


3. Save and close .zshrc


4. Then type:
   

   flutter doctor
   

   
   

Had the same issue and just realized that I forgot to add the close quote

有同样的问题，只是意识到我忘了添加右引号

So the correct way is to add to .zshrc by typing vim ~/.zshrc

因此，正确的方法是通过键入vim~/.zshc来添加到.zshc

PATH="$PATH:$HOME/Flutter/flutter/bin"

or

或

export PATH="$PATH:/YOUR_FLUTTER_DIR/flutter/bin"

then run source ~/.zshrc or just open a new terminal window

然后运行~/.zshrc源文件或打开一个新的终端窗口

I tried installing flutter on my MAC according to the advice here, but it still doesn't work, after searching for it I found an article here.

我试着按照这里的建议在我的Mac上安装Fflight，但仍然不起作用，搜索后我发现了一篇文章在这里。

So, I change my .zshrc file to:

因此，我将我的.zshc文件更改为：

export PATH="$PATH:/Users/YOUR_PROVILE_NAME/YOUR_DEVELOPMENT_FOLDER/flutter/bin"

Change YOUR_PROVILE_NAME to your name profile, also YOUR_DEVELOPMENT_FOLDER to your development folder for flutter

将您的_provile_name更改为您的姓名配置文件，并将您的_Development_Folders更改为您的Ffltter的开发文件夹

and now it's working.

现在它起作用了。

Note:
I use Catalina OS v10.15.4

注意：我使用的是Catalina OS v10.15.4

I followed URL to resolve my issue.

我跟随URL解决了我的问题。

I simply created a .zshrc file which was not exist then added my PATH variables copied from existing .bashrc.

我只是创建了一个不存在的.zshrc文件，然后添加了从现有.bashrc复制的PATH变量。

I had the same problem when upgrading to mac Catalina 10.15.4:

我在升级到Mac Catalina 10.15.4时遇到了同样的问题：

After many days of research, I have achieved success. Here are the steps I did:

经过多天的研究，我取得了成功。以下是我所做的步骤：

First, open the terminal on your mac.

首先，在你的Mac上打开终端。

Next, use the command

接下来，使用命令

 cat .bash_profile

and copy the content.

并复制内容。

Then type this command into the terminal:

然后在终端中键入以下命令：

nano $ HOME / .zshrc

and paste the content just copied above into. Save then type

然后把上面复制的内容粘贴到。保存然后键入

source $ HOME / .zshrc

to refresh this file. Next type

以刷新此文件。下一个类型

echo $ PATH

to see if the content has been updated. If successful type

查看内容是否已更新。如果成功，请键入

flutter --version

and you will see the result.

你会看到结果的。

There are quite a few answers mentioned above pretty much same. I would say worth seeing into the SHELL using echo $SHELL command,

上面提到的相当多的答案基本相同。我认为值得使用ECHO$SHELL命令深入了解外壳，

If you’re using Bash, edit $HOME/.bash_profile or $HOME/.bashrc. If you’re using Z shell, edit $HOME/.zshrc. If you’re using a different shell, the file path and filename will be different on your machine.

如果您正在使用Bash，请编辑$HOME/.bash_PROFILE或$HOME/.bashrc。如果您使用的是ZShell，请编辑$HOME/.zshc。如果您使用的是不同的外壳程序，则您的计算机上的文件路径和文件名也会不同。

N.B. Don't forget you need to add VIM before either command in the terminal app.

注意：别忘了，你需要在终端应用程序中的任一命令之前添加vim。

For me .zshrc worked instead of .zprofile. I believe this is because I had created .zshrc earlier and now when I tried creating .zprofile, it was looking into .zshrc file.

对我来说，.zshc代替.zprofile起作用。我相信这是因为我之前创建了.zshc，而现在当我尝试创建.zprofile时，它正在查看.zshc文件。

You can check if .zshrc file using ls -a command

您可以使用ls-a命令检查.zshc文件

For me moving the flutter folder to document page and setting the new path solved the issue

对于我来说，将Ffltter文件夹移动到文档页面并设置新路径解决了问题
