【问题描述】：

我正在尝试使用以下命令使用 travis ci 构建我的 react-native 项目：

script: 
    - npm install -g npx && cd android && sudo chmod +x gradlew && sudo ./gradlew assembleRelease#3

但是，我的构建失败并出现以下错误：无法运行程序“npx”：错误=2，没有这样的文件或目录

我的完整配置如下：

language: android
before_install: #1.1
- nvm install 10
- node --version
install: #1.2
- npm install
android: #1.3
  components:
  - build-tools-23.0.1
  - android-23
  - extra-android-m2repository
  - extra-google-google_play_services
  - extra-google-m2repository
  - addon-google_apis-google-16
script: 
    - npm install -g npx && cd android && sudo chmod +x gradlew && sudo ./gradlew assembleRelease#3
deploy: # mostly generated by `> travis deploy releases`
  skip_cleanup: true

即使我已使用 npm 全局安装，构建文件似乎也无法找到 npx。在错误所在的native_modules.gradle文件中，错误行如下：

def npx = Os.isFamily(Os.FAMILY_WINDOWS) ? "npx.cmd" : "npx"

这是发生错误的调用堆栈：

我通过添加 openjdk8 并设置我的 android sdk 路径解决了我的问题。对我来说完整的工作配置：

os:
- linux
before_install:
- curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
- sudo apt-get install -y nodejs
- npm --version
- node --version
- npx --version
- export ANDROID_HOME=/usr/local/android-sdk
- export PATH=$PATH:$ANDROID_HOME/emulator
- export PATH=$PATH:$ANDROID_HOME/tools
- export PATH=$PATH:$ANDROID_HOME/tools/bin
- export PATH=$PATH:$ANDROID_HOME/platform-tools
- git clone https://github.com/facebook/watchman.git -b v4.9.0 --depth 1
- cd watchman
- "./autogen.sh"
- "./configure"
- make
- sudo make install
- cd ..
install:
- npm install
language: android
jdk:
- oraclejdk8
dist: trusty
android:
  components:
  - tools
  - platform-tools
  - build-tools-28.0.3
  - android-28
  - extra-google-google_play_services
  - extra-google-m2repository
  - extra-android-m2repository
script:
- cd android && sudo chmod +x gradlew && sudo ./gradlew clean && sudo ./gradlew assembleRelease
