看了很多帖子,都说和vue2.7 不兼容,需要降级到2.0.x,但还是没有效果,pinia 2.x的最后更新版本也支持2.7,使用yarn可以运行,使用pnpm就报错

问题分析
由于 vue-demi 被 Ignored build scripts(忽略了构建脚本),它无法执行安装后的 postinstall 脚本。
为什么这会导致报错? vue-demi 是 Pinia 兼容 Vue 2 和 Vue 3 的核心桥梁。它在安装时需要运行一个脚本来检测你当前项目是 Vue 2 还是 Vue 3,并据此"切换"导出的 API。
因为 pnpm 默认禁用了未授权的脚本运行,vue-demi 没能成功切换。
结果它默认指向了 Vue 3 的导出路径,导致 Pinia 去调用 Vue 2.7 根本不存在的 hasInjectionContext,从而引发了你看到的错误。
解决办法
授权并重新构建 在终端运行以下命令:
sh
pnpm approve-builds
空格选中 vue-demi
sh
pnpm approve-builds
√ Choose which packages to build (Press <space> to select, <a> to toggle all, <i> to invert selection) · vue-demi
√ The next packages will now be built: vue-demi.
Do you approve? (y/N) · true
node_modules/.pnpm/vue-demi@0.14.10_vue@2.7.16/node_modules/vue-demi: Running postinstall script, done in 127ms
再次执行pnpm dev 即可
