初始化Weex項目遇到的問題記錄

Weex 提供了一個命令行工具 weex-toolkit 來幫助開發者使用 Weex。它能夠用來快速建立一個空項目、初始化 iOS 和 Android 開發環境、調試、安裝插件等操做。html

目前 weex-toolkit 只支持建立 Vue.js 的項目。建立 Rax 的項目可使用 rax-cli,參考 Rax 的官方網站 瞭解其用法。vue

一:初始化 (全局安裝 weex-toolkit

請確保你已經安裝了 Node.js (能夠參考React Native (0.57)開發環境搭建(過程記錄)中Node.js的安裝過程)html5

而後全局安裝 weex-toolkitnode

命令以下:android

npm install -g weex-toolkitwebpack

可是事與願違,報錯,而且很噁心,怎麼搞都沒有辦法。ios

解決過程重點記錄:git

多是我使用了左邊的推薦的10.14.2版本(記不清了),致使「水土不服」。出現下面的問題:github

一、警告web

WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modules/weex-toolkit/node_modules/weex-builder/node_modules/fsevents):

WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 install: `node install`

WARN optional SKIPPING OPTIONAL DEPENDENCY: Exit status 1

WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.2 (node_modules/weex-toolkit/node_modules/weex-previewer/node_modules/fsevents):

二、直接錯誤:

Tried to download(undefined): https://fsevents-binaries.s3-us-west-2.amazonaws.com/v1.1.3/fse-v1.1.3-node-v64-darwin-x64.tar.gz 

Pre-built binaries not found for fsevents@1.1.3 and node@10.14.2 (node-v64 ABI, unknown) (falling back to source compile with node-gyp)

ERR! node -v v10.14.2

node-gyp -v v3.8.0

not ok 

build error

node -v v10.14.2

node-pre-gyp -v v0.6.39

not ok 

。。。。

 

就是以上相似問題。

解決方案:

一、下降node的版本號:

npm install -g n

sudo n v8.11.3

       install : node-v8.11.3

       mkdir : /usr/local/n/versions/node/8.11.3

       fetch : https://nodejs.org/dist/v8.11.3/node-v8.11.3-darwin-x64.tar.gz

######################################################################## 100.0%

   installed : v8.11.3

$ node -v

v8.11.3

$ npm -v

5.6.0

安裝了node:v8.11.3 版本後,嘗試初始化,執行以下命令,並記錄過程:

$ npm install weex-toolkit -g

/usr/local/bin/weex -> /usr/local/lib/node_modules/weex-toolkit/bin/weex.js

> fsevents@1.1.3 install /usr/local/lib/node_modules/weex-toolkit/node_modules/weex-builder/node_modules/fsevents

> node install

[fsevents] Success: "/usr/local/lib/node_modules/weex-toolkit/node_modules/weex-builder/node_modules/fsevents/lib/binding/Release/node-v57-darwin-x64/fse.node" already installed

Pass --update-binary to reinstall or --build-from-source to recompile

> fsevents@1.1.2 install /usr/local/lib/node_modules/weex-toolkit/node_modules/weex-previewer/node_modules/fsevents

> node install

[fsevents] Success: "/usr/local/lib/node_modules/weex-toolkit/node_modules/weex-previewer/node_modules/fsevents/lib/binding/Release/node-v57-darwin-x64/fse.node" already installed

Pass --update-binary to reinstall or --build-from-source to recompile

> fsevents@1.1.3 install /usr/local/lib/node_modules/weex-toolkit/node_modules/weex-previewer/node_modules/weex-builder/node_modules/fsevents

> node install

[fsevents] Success: "/usr/local/lib/node_modules/weex-toolkit/node_modules/weex-previewer/node_modules/weex-builder/node_modules/fsevents/lib/binding/Release/node-v57-darwin-x64/fse.node" already installed

Pass --update-binary to reinstall or --build-from-source to recompile

> fsevents@1.1.3 install /usr/local/lib/node_modules/weex-toolkit/node_modules/xtoolkit/node_modules/fsevents

> node install

[fsevents] Success: "/usr/local/lib/node_modules/weex-toolkit/node_modules/xtoolkit/node_modules/fsevents/lib/binding/Release/node-v57-darwin-x64/fse.node" already installed

Pass --update-binary to reinstall or --build-from-source to recompile

+ weex-toolkit@1.3.11

added 463 packages and updated 1 package in 22.24s

整個過程沒有出現問題

二、升級到最新版本的node.js

接着剛纔的去安裝最新的node.js

$ brew install node

Warning: node 11.4.0 is already installed, it's just not linked

You can use `brew link node` to link this version.

$ brew link node

Linking /usr/local/Cellar/node/11.4.0... 

Error: Could not symlink bin/node

Target /usr/local/bin/node

already exists. You may want to remove it:

  rm '/usr/local/bin/node'

To force the link and overwrite all conflicting files:

  brew link --overwrite node

To list all files that would be deleted:

  brew link --overwrite --dry-run node

果真node版本以下,沒有改變:

$ node -v

v8.11.3

$ npm -v

5.6.0

嘗試用下面的命令

$ sudo n v11.4.0

$ node -v

v11.4.0

$ npm -v

6.4.1

更新到最新的版本了。

$ npm install weex-toolkit -g

WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but npm-shrinkwrap.json was generated for lockfileVersion@0. I'll try to do my best with it!

WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but npm-shrinkwrap.json was generated for lockfileVersion@0. I'll try to do my best with it!

WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but npm-shrinkwrap.json was generated for lockfileVersion@0. I'll try to do my best with it!

/usr/local/bin/weex -> /usr/local/lib/node_modules/weex-toolkit/bin/weex.js

+ weex-toolkit@1.3.11

updated 229 packages in 20.484s

在最新的版本下面的時候,只剩餘警告了。綜上所述,我覺的仍是使用v8.11.3靠譜點。

二:初始化 (weex create awesome-app )

npm install weex-toolkit -g

這條命令會向你命令行環境中註冊一個 weex 命令。你能夠用 weex create 命令來建立一個空的模板項目:

$ weex create awesome-app 

【我以爲上面的命令 awesome-app  能夠隨便寫,例如 $ weex create yooweiweex  而後在肯定Project name的時候,有一次機會:? Project name yooweiweex】

以下;

$ weex create awesome-app

? Project name yooweiweex 【能夠本身指定,也可直接回車,按照括號中默認名字(注意這裏的名字不能有大寫字母,若是有會報錯Sorry, name can no longer contain capital letters)】

? Project description test weex

? Author yoowei <wyhist2012@126.com>

? Select weex web render latest

? Babel compiler (https://babeljs.io/docs/plugins/#stage-x-experimental-presets) stage-0

? Use vue-router to manage your view router? (not recommended) Yes

? Use ESLint to lint your code? Yes

? Pick an ESLint preset Standard

? Set up unit tests Yes

? Should we run `npm install` for you after the project has been created? (recommended) npm

16:31:26 : Generated awesome-app

# Installing project dependencies ...

# ========================

 可是多是使用了node的最高版本,中間仍是出現了不少錯誤和警告。我以爲有必要將node降到v8.11.3 使用

注意爲了不出現一些其餘的亂七八糟的問題,咱們仍是按照下面的兩個注意事項去處理
一、前往/usr/local/lib/node_modules 目錄現將weex-toolkit 刪掉

二、回到根路徑/Users/galahad 而後再去執行:$ npm install weex-toolkit -g

 

$ cd /Users/galahad/Desktop/ziliao/weex 

$ weex create yooweiweex

? Project name yooweiweex

? Project description A weex project

? Author yoowei <wyhist2012@126.com>

? Select weex web render latest

? Babel compiler (https://babeljs.io/docs/plugins/#stage-x-experimental-presets) stage-0

? Use vue-router to manage your view router? (not recommended) No

? Use ESLint to lint your code? Yes

? Pick an ESLint preset Standard

? Set up unit tests Yes

? Should we run `npm install` for you after the project has been created? (recommended) npm

# ========================

> yooweiweex@1.0.0 lint /Users/galahad/Desktop/ziliao/weex/yooweiweex

> eslint --ext .js,.vue src  test/unit --fix

 

Success! Created yooweiweex at /Users/galahad/Desktop/ziliao/weex/yooweiweex

 Inside that directory, you can run several commands:

 

 npm start

  Starts the development server for you to preview your weex page on browser

  You can also scan the QR code using weex playground to preview weex page on native

 

  npm run dev

  Open the code compilation task in watch mode

 

  npm run ios

  (Mac only, requires Xcode)

  Starts the development server and loads your app in an iOS simulator

 

  npm run android

  (Requires Android build tools)

  Starts the development server and loads your app on a connected Android device or emulator

 

  npm run pack:ios

  (Mac only, requires Xcode)

  Packaging ios project into ipa package

 

  npm run pack:android

  (Requires Android build tools)

  Packaging android project into apk package

 

  npm run pack:web

  Packaging html5 project into `web/build` folder

 

  npm run test

  Starts the test runner

 

To get started:

 

  cd yooweiweex

  npm start

 

Enjoy your hacking time!

 

命令執行完之後,在當前目錄的 awesome-app 文件夾裏就有了一個空的 Weex + Vue.js 項目。

 

三:開發

下一步就是進入剛剛建立的文件夾,而且安裝依賴,而後執行 npm start

cd yooweiweex

npm install

npm start

而後工具會啓動一個本地的 web 服務,監聽 8081 端口。你能夠打開 http://localhost:8081 查看頁面在 Web 下的渲染效果。 源代碼在 src/ 目錄中,你能夠像一個普通的 Vue.js 項目同樣來開發.

除此以外,你還能夠打開 http://localhost:8081/preview.html 開啓一個預覽頁面,它會把 web 端的頁面放在一個 iframe 中渲染,並且在右側生成一個二維碼。用 Weex playground app 掃描這個二維碼能夠看到頁面在手機上渲染的真實效果。

四:編譯和運行

默認狀況下 weex create 命令並不初始化 iOS 和 Android 項目,你能夠經過執行 weex platform add 來添加特定平臺的項目。

weex platform add ios
weex platform add android

因爲網絡環境的不一樣,安裝過程可能須要一些時間,請耐心等待。若是安裝失敗,請確保本身的網絡環境暢通。

 

$ cd /Users/galahad/Desktop/ziliao/weex/yooweiweex 

$ weex platform add ios

17:13:20 : Adding ios weexpack-ios@4.1.6 ...

17:13:20 : Success!

$ weex platform add android

17:16:23 : Adding android weexpack-android@6.3.17 ...

17:16:23 : Success!

爲了能在本地機器上打開 Android 和 iOS 項目,你應該配置好客戶端的開發環境。對於 iOS,你應該安裝而且配置好 Xcode。對於 Android,你應該安裝而且配置好 Android Studio。當開發環境準備就緒後,運行下面的命令,能夠在模擬器或真實設備上啓動應用:

固然仍是在$ cd /Users/galahad/Desktop/ziliao/weex/yooweiweex這個目錄下面:

weex run ios
weex run android
weex run web

五:調試

weex-toolkit 還提供了強大的調試功能,只須要執行:

weex debug

這條命令會啓動一個調試服務,而且在 Chrome (目前只支持基於 V8 引擎的桌面瀏覽器) 中打開調試頁面。詳細用法請參考 weex-toolkit 的文檔
