Previously on:

Download the node installation package from the nodejs official website, install node, use the npm install-g yarn command to install yarn globally, and then use the yarn global add @ vue/cli command to successfully install the global vue-cli.

1. Determine if nodejs and global vue-cli are installed, both of which I have installed here.

two。 Specific description of the problem:

Vue-cli has been installed globally using yarn and has been successfully installed, but when using the vue--version command, an error was reported as "vue is not an internal or external command", that is, the relevant command of vue cannot be used at this time.

3. Solution:

Find the storage location of the vue.cmd file on your computer and add it to the environment variable.

4. Specific methods:

① searches the computer for vue.cmd globally and copies its storage path in the computer

* * another: * * if the situation is the same as mine (vue-cli installed with yarn), you can also run yarn global dir to get the global path of yarn

Copy the path of yarn to your computer and open the node_modules under that directory, as well as the .bin folder under it. You can get the path of vue.cmd. Here is the path of my vue.cmd. Copy it.

The purpose of step ① is to get the local storage path of vue.cmd.

Under the computer icon on the desktop, right-click, Properties, and find the advanced system settings, as shown in the figure:

Click the environment variable in the advanced system variables:

Double-click path, in the pop-up box of the edit environment variable, click the "New" button, and paste the storage path of the vue.cmd you just copied into the new editing area. Click OK after the settings are complete.
