npm - "npm install"给出错误消息 "invalid"，这是什么？

Question

请检查图片。

我猜它与 package.json 有关但我不太确定。

最初我正在安装 material-ui .

详细消息在这里:

I:\react-boilerplate>npm install material-ui

react-boilerplate@3.4.0 I:\react-boilerplate

+-- material-ui@0.17.1

| +-- keycode@2.1.8

| +-- lodash.throttle@4.1.1

| +-- UNMET PEER DEPENDENCY react@^15.4.2

| +-- react-addons-create-fragment@15.4.2

| +-- react-addons-transition-group@15.4.2

| +-- react-event-listener@0.4.3

| | +-- UNMET PEER DEPENDENCY react@^15.4.2

| | `-- react-addons-shallow-compare@15.4.2

| +-- recompose@0.22.0

| | `-- change-emitter@0.1.3

| `-- simple-assign@0.1.0

+-- UNMET PEER DEPENDENCY react-tap-event-plugin@^2.0.1

`-- UNMET PEER DEPENDENCY webpack@2.2.0-rc.3

然后我试图通过 npm install 修复 UNMET PEER DEPENDENCY他们。

第一次尝试给出了这个:

react-boilerplate@3.4.0 I:\react-boilerplate

+-- react@15.4.2 invalid

+-- react-tap-event-plugin@2.0.1

`-- UNMET PEER DEPENDENCY webpack@2.2.0-rc.3

`-- webpack-sources@0.1.5

如您所见，这是第一个 invalid我遇见了。

所以我只是想弄清楚为什么会这样 invalid弹出以及如何修复它。

此处的无效依赖项表明安装了不适当版本的依赖项包。在这种情况下，您的项目正在请求 webpack@2.2.0-rc3 , 但版本 2.2.1而是安装了。请注意，版本范围内没有插入符号 (^) 或波浪号 (~)，这意味着 2.2.1不是有效匹配。

React 发生了另一个冲突，它在版本 15.4.1 中已修复。并且应该升级到版本范围^15.4.2 ，根据其他依赖项(例如 material-ui )的要求。

为了设置新版本的依赖项(升级/降级)，不要忘记各自的保存标志( --save/-S 或 --save-dev/-D )。

npm install -S react@^15.4.2

不幸的是， react-tap-event-plugin取决于版本 2.2.0-rc3 webpack，所以你不应该升级 webpack。相反，您可以调用 npm update --dev 确保所有注册的依赖项都安装了正确的版本。如果一切都失败了，一个天真的但有效的技巧是删除 node_modules 文件夹并从头开始安装所有包。
