@yutiansut vue-template-compiler@2.1.5 renamed _h to _c, vuejs/vue#4536

Related to vuejs/vue@4b51ad0

[yutiansut]

this._h to this.$createElement 我看到一个解决办法是这样?

[hilongjw]

@yutiansu vue and vue-template-compiler are both upgraded to 2.1.5 or later

[yutiansut]

vue 是2.8版本

PS C:\Users\yutia> vue -V 2.8.0

vue-template-compiler我不知道怎么查版本号

我先修改了package.json里的要求

  "dependencies": {
    "express": "^4.14.0",
    "pug": "^2.0.0-beta6",
    "serialize-javascript": "^1.3.0",
    "vue": "^2.0.1",
    "vue-router": "^2.0.0",
    "vue-server-renderer": "^2.0.1",
    "vue-ssr": "^0.2.2",
    "vue-template-compiler": "^2.1.5",
    "vuex": "^2.0.0-rc.3",
    "vuex-router-sync": "^3.0.0"
  },

再npm i 这样行吗

[hilongjw]

可以的

[yutiansut]

还是在大量报错 cmd页面全是滚滚的错误我都来不及复制.... 基本都是类似这个,似乎还是_h的问题

[yutiansut]

所以是我需要降级版本号是吗?

[hilongjw]

npm i vue@2.1.8 --save
npm i vue-template-compiler@2.1.8 --save

[yutiansut]

执行以后出来这个结果

PS D:\projects\collections\vueexample\vue-ssr-hmr-template> npm i vue@2.1.8 --sace-dev
npm WARN update-linked node_modules\vue needs updating to 2.1.8 from 2.1.10 but we can't, as it's a symlink
npm WARN cov-x@ No repository field.

PS D:\projects\collections\vueexample\vue-ssr-hmr-template> npm i vue-template-compiler@2.1.8 --sace-dev
npm WARN update-linked node_modules\vue-template-compiler needs updating to 2.1.8 from 2.1.10 but we can't, as it's a symlink

[hilongjw]

npm i vue@2.1.10 --save
npm i vue-template-compiler@2.1.10 --save

[yutiansut]

降级不成功诶

PS D:\projects\collections\vueexample\vue-ssr-hmr-template> npm i vue@2.1.8 --save
npm WARN update-linked node_modules\vue needs updating to 2.1.8 from 2.1.10 but we can't, as it's a symlink

这里安装不了指定版本的问题应该是npm 的bug, 你是window？ https://github.com/npm/npm/issues/10013
