docker 服务器提前终止，状态为 127

Question

我的Windows 10机器上有一个工作示例。当我通过使用 node：8 的容器将其移植到 linux 时，我收到错误 127。

我对 Linux 或基本要求不够熟悉，即它是否需要 Java 安装或其他？

Dockerfile

FROM node:8

# Create and define the node_modules's cache directory.
RUN mkdir /usr/src/cache
WORKDIR /usr/src/cache
COPY . .
RUN npm install
# run update to get all drivers
RUN npm run webdriver-update
## update to specific chrome version - 78.0.3904.105
RUN npm run webdriver-update-chrome
# overwrite any remaining references to wrong chromedriver...
RUN sed -i -e 's/chromedriver[^"]*/chromedriver_78.0.3904.105/g' node_modules/protractor/node_modules/webdriver-manager/selenium/update-config.json
# run tests
RUN npm run test-protractor

上面的 sed 命令很简单，确保 update-config.json 使用的是上面选择的 chrome 版本。

update-config.json

例如：

"node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_78.0.3904.105.exe"

Answer 2

如果我删除对特定 chrome 版本的引用，然后只运行 webdriver-manager update，如下所示：

码头工人文件

FROM node:8

# Create and define the node_modules's cache directory.
RUN mkdir /usr/src/cache
WORKDIR /usr/src/cache
COPY . .
RUN npm install
# run update to get all drivers
RUN npm run webdriver-update
# run tests
RUN npm run test-protractor

这是我的错误

我注意到我的配置中有一个错误，并更正了"忽略未捕获异常"，末尾的 s =

exports.config = {
...
ignoreUncaughtExceptions: true,

虽然它不能解决问题。我仍然遇到同样的问题。

update-config.json
