Problem Description
使用vue命令出现错误
Installation steps of the vue command:
- npm install yarn -g : install yarn
- yarn global add @vue/cli : use this command to install vue scaffolding
- vue create project name: use this command to create a project
After inputting according to the above steps, the vue scaffolding is successfully installed, but an error is reported zsh: command not found: vue, resulting in the failure of project creation
Cause Analysis:
The execution command cannot be found, and the location of the installation package needs to be told to the system
The yarn command is installed under .yarn/bin by default
Enter the following command to view the yarn installation package
ls ~/.yarn/bin
Enter the following command to find the installation location of yarn
cd ~/.yarn/bin
pwd
solution:
Modify the .bash_profile or .zshrc file
Since I have modified .bash_profilethe content when I installed yarn, I found that the vue command still cannot be found, so I am modifying it here.zshrc
vim ~/.zshrc
.zshrcAdd the following command on the last line of :
export PATH="/Users/[用户名]/.yarn/bin:$PATH"
After using :wqsave, enter the following command
source ~/.bash_profile
Enter again at this time
vue -v
If the above content appears, it means success!
