找不到命令 - Oh-My-Zsh

Question

I recently installed zsh and oh-my-zsh in my Mac. Now when I try to run a maven command from the terminal, I am getting the following error.

$ mvn install
zsh: command not found: mvn

I have installed Apache maven in /Applications directory. Currently my.zshrc file looks like below.

plugins=(git brew pip mvn mysql-macports python sublime tmux osx)

# ####################
# Maven Config Options
# ####################
export M2_HOME=/Applications/apache-maven-3.3.3
export PATH=$PATH:M2_HOME/bin

As seen above, I appended location of maven installation to the path. But I am still getting errors. Any help is appreciated.

Answer 1

Question:

➜ ~ mvn

zsh: command not found: mvn

Answer:

step 1:

vim ~/.zshrc

step 2:(Add at the end of the file)

source ~/.bash_profile;

step 3:(Execution shell)

> source ~/.bash_profile

You can use mvn :

➜ / mvn

[INFO] Scanning for projects... .......

Answer 2

Just add:

source ~/.bash_profile

to .zshrc

Answer 3

I had a similar problem after installing oh-my-zsh, but for adb command. Looks like the PATH is shortened when oh-my-zsh is installed. I solved it using following steps.

1. Open the .zshrc file

   sudo nano ~/.zshrc

2. Look for # User configuration

   Un-comment the following line:

    export PATH="/usr/bin:/bin:/usr/sbin:/sbin:$PATH"

3. Save the file.

4. source ~/.zshrc

Give this one a try for other similar command not found errors.

Answer 4

Try below steps:

Open terminal and run command vi ~/.zshrc

Add below lines in file:

export M2_HOME=/Users/<username>/Downloads/apache-maven-3.6.3 
export PATH=${M2_HOME}/bin:${PATH} 
export PATH

Save file successfully

Open another terminal instance & run command mvn -version

It should work!

Answer 5

• First, as 4ae1e1 pointed out, you missed the $ in PATH=$PATH:M2_HOME/bin
• Second, don't forget to run source ~/.zshrc to take the settings into effect instantly.

Answer 6

As mentioned by @4ae1e1 in his comment, $ have to be added before M2_HOME while referring it in the PATH variable, as follows:

export M2_HOME=/Applications/apache-maven-3.3.3
export PATH=$PATH:$M2_HOME/bin/

Once added, as others suggested, source the ~/.zshrc file.

Answer 7

Step 1: open zshrc file

sudo nano ~/.zshrc

step 2: add 'mvn' in plugins section

plugins=(git zsh-autosuggestions mvn)

step 3: add maven configuration in zshrc file. ( make sure your apache maven extract directory. I have extracted in /opt folder )

# Maven Config Options
export M2_HOME=/opt/apache-maven-3.8.4
export M2=$M2_HOME/bin
export PATH=$M2:$PATH

step 4: save the chnages

ctrl+o
ENTER
ctrl+z

Step 5: reload zshrc file

source ~/.zshrc

Step 6: go to terminal and verify

mvn -v

Output :

Apache Maven 3.8.4
 Maven home: /opt/apache-maven-3.8.4
 Java version: 11.0.11, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11- 
 openjdk-amd64 Default locale: en_IN, platform encoding: UTF-8 OS name: 
 "linux", version: "5.4.0-89-generic", arch: "amd64", family: "unix"

Answer 8

I faced the exact same issue, this is what worked for me:

1. sudo nano ~/.zshrc

2. add this:

    export PATH=your maven path/apache-maven-3.6.3/bin:/usr/bin:/bin:/usr/sbin:/sbin

3. Ctrl + X , select "Y", Press Enter

4. source ~/.zshrc

5. Validate: mvn -version

Answer 9

On macOS, you can add the following to your .zshrc file.

If you have not, download maven from https://maven.apache.org/download.cgi

# Maven
export PATH=/opt/apache-maven-3.8.3/bin:${PATH} # you could have it in a different directory 

To edit .zshrc, you can use an existing text editor such as vim.

$ cd ~
$ vim .zshrc 

Use i to insert the export statements. Once inserted, use esc to exit insert mode. Then use :wq! to save and quit the editor. Finally, source the file to see the effects of your new changes.

$ source .zshrc

Now try mvn and you should see something like this.

Answer 10

I think the answers above are too deep. It could be that the person does not have Maven installed on their Local PC. So please run the command below on your terminal

brew install maven

Afterwards on your IntelliJ or the terminal where the project is located run the command

mvn clean install

Use the command to double check if it was installed mvn --version

Answer 11

vi ~/.zshrc

add source ~/.bash_profile to ~/.zshrc file, after the line source $ZSH/oh-my-zsh.sh

open up a new terminal tab and execute mvn , and it will start working.

Answer 12

I had the same issue. So created .zshrc file and added below in that file. export M2_HOME=/Users/gandharavmehra/Desktop/Development/Tools/apache-maven-3.6.3 export PATH=$PATH:$M2_HOME/bin

after this gandharvmehra@MacBook-Pro ~ % source ~/.zshrc

close the Terminal and open again

gandharamehra@MacBook-Pro ~ % mvn -version Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

it should work 100 percent

Answer 13

Combining other answers I got adb working on mac and zsh appending these two path lines to .zshrc:

# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
# this are for Android Studio adb:
export PATH=~/Android/sdk/tools:$PATH
export PATH=~/Android/sdk/platform-tools:$PATH

Answer 14

实际上， .bash_profile用于/bin/bash shell，对于您的/bin/zsh shell，该文件称为.zprofile ，您应该在.zprofile中执行与.bash_profile中相同的操作

Answer 15

I have similar issue today with mvn command not found

In my example problem was with incorrect path - I missed one / at the beginning of the path

1. .zshrc before change: export MAVEN_HOME=home/user/Tools/apache-maven-3.6.3 export PATH=$MAVEN_HOME/bin:$PATH
2. good to verify if maven path exists. In my case it was error using command below ls $MAVEN_HOME
3. .zshrc after fix one line export MAVEN_HOME=/home/user/Tools/apache-maven-3.6.3 export PATH=$MAVEN_HOME/bin:$PATH
4. reload .zhsrc source .zshrc
5. mvn command found

Answer 16

If you are running Catalina you will face this problem often.

1. Open your terminal
2. Just copy all your Path variables and create a .zshrc file (touch .zshrc)
3. open it (open ~/.zshrc) and paste them there,
4. save and refresh your .zsrhc file ( source ~/.zshrc).

Answer 17

You wouldn't happen to be on IntelliJ would you?

Have you tried typing your command "mvn install" and pressing Command + Enter?

I get this all the time and this usually fixes it.

Answer 18

Install Maven on Mac OS. Download the latest version from the Apache Maven site and select the Maven binary tar.gz file, for example, apache-maven-3.8.4-bin.tar.gz.

Then we extract the archive to our desired location.

Adding Maven to the Environment Path

First, let's open the terminal and switch to the directory where the files were extracted to and then log in as superuser or use below commands with sudo.

Second, we need to remove the tar.gz archive:

rm Downloads/apache-maven*bin.tar.gz

Third, we have to fix the permissions and switch the Maven contents:

chown -R root:wheel Downloads/apache-maven*

mv Downloads/apache-maven* /opt/apache-maven

Then, let's archive the Admin session and add Maven binaries to the path and append:

exit

nano $HOME/.profile

export PATH=$PATH:/opt/apache-maven/bin

Finally, we use Ctrl+x to save and exit from nano.

To load the new setup, let's run:

bash Now, we test if Maven is installed successfully using the command below:

mvn -version

We are now ready to use Maven on our Mac OS.

如果您使用的是 Mac，则可以使用 Homebrew 安装 maven 及其所有路径使用：

brew install maven

Answer 20

If you want to configure intelliJ terminal with a custom Terminal or if you want fix "command not found", follow these steps:

1. Click > File
2. Click > Settings
3. Click > Tools
4. Click > Terminal
5. Edit "Shell path" @ "Application Settings", change current path with: C:\Users\Work\AppData\Local\Programs\Git\bin\sh.exe --login

// The path you may have differs based on your OS, in example: "installationPath\Terminal Folder\bin\sh.exe --login"

6. Click > Apply
7. Click > Ok

I used git bash but technically it should work with every terminal. Do not forget to add --login after the *.exe

Answer 21

in my case it was a syntax error:

The wrong usage was like this:

export PATH="$PATH:/Applications/Visual Studio Code.app/Contents/Resources/app/bin"
export PATH="$PATH:/Applications/Webstorm.app"

I updated:

export PATH="/Applications/Visual Studio Code.app/Contents/Resources/app/bin:$PATH"
export PATH="/Applications/Webstorm.app:$PATH"

and now it works

Answer 22

First of all Download Maven from here https://maven.apache.org/download.cgi

and extract it and go and open your zshrc with nano :

nano ~/.zshrc

and paste these lines inside the file:

export M2_HOME="/Users/sanaebadi/Downloads/apache-maven-3.8.7"
PATH="${M2_HOME}/bin:${PATH}"
export PATH

**

you have to make sure that you put your correct USER name instead of my userName (sanaebadi)

**

and you have to make sure from the version and directory of your maven that you already downloaded.

**

**

and relaunch the file after it: source ~./zshrc

and run this command to make sure you installed the maven on your system:

 mvn -version

you must to see some lines start with:

Apache Maven 3.8.7 (b89d5959fcde851dcb1c8946a785a163f14e1e29)
Maven home: /Users/sanaebadi/Downloads/apache-maven-3.8.7 ...
.....
...

Done!

Answer 23

step 1:

vim ~/.zshrc

step 2:(Add at the end of the file)

source ~/.bash_profile;

step 3 : (Save changes in Vim)

 :wq!

step 4:(Execution shell)

> source ~/.bash_profile

Answer 24

Best solution work for me

Open Finder-> go to folder /Users/ /usr/local/bin

open .zshrc with TextEdit

.zshrc is hidden file so unhide it by command+shift+. press

delete file content and type

export PATH=~/usr/bin:/bin:/usr/sbin:/sbin:$PATH

and save

now

zsh: command not found Gone
