使用vue启动的时候，出现了：

npm run serve
&gt; vue3-<span style="color:#dcc6e0">admin</span>@<span style="color:#f5ab35">0.0</span><span style="color:#f5ab35">.0</span> serve
&gt; vite preview
sh: <span style="color:#f5ab35">1</span>: vite: <span style="color:#dcc6e0">not</span> <span style="color:#f5ab35">found</span>
linlin@linlin-i5:/workspace/vue3_learn_admin$ ls
config  ecosystem.config.js  LICENSE       package.json       <span style="color:#f5ab35">public</span>     src    vite.config.js        yarn.<span style="color:#dcc6e0">lock</span>
dist    <span style="color:#dcc6e0">index</span>.html           node_modules  package-<span style="color:#dcc6e0">lock</span>.json  README.md  theme  vue3-<span style="color:#dcc6e0">admin</span>-<span style="color:#dcc6e0">server</span>.js

说明没有安装需要的依赖vite

<span style="color:#abe338">npm</span> <span style="color:#abe338">install</span> -<span style="color:#abe338">g</span> <span style="color:#f5ab35">create-vite</span>

或者

<span style="color:#abe338">yarn</span> <span style="color:#abe338">global</span> <span style="color:#abe338">add</span> <span style="color:#f5ab35">create-vite</span>

然后：

在项目文件夹，删除 

node_modules
文件夹和 
package-lock.json
（或 
yarn.lock
）文件。

重新安装依赖：

npm <span style="color:#dcc6e0">install</span>

或

<span style="color:#ffd700">yarn</span>

如果过程没有任何错误，就启动：

npm run serve

以上是理想的情况，实际上我的：

npm <span style="color:#dcc6e0">install</span> -g <span style="color:#dcc6e0">create</span>-vite
added <span style="color:#f5ab35">1</span> <span style="color:#dcc6e0">package</span> <span style="color:#dcc6e0">in</span> <span style="color:#f5ab35">1</span>s

启动（成功）

npm <span style="color:#f5ab35">run</span> serve
