问题描述
在本地，我已经通过以下方式成功安装了npm @ 5：
Locally, I have successfully installed npm@5 via:
$ npm install npm@5 -g
$ npm -v
$ 5.0.0
在本地，我可以运行npm设置很好（基本上是 npm i&&tsc ）
And locally, I can run the npm setup just fine (it's basically npm i && tsc)
$ npm run setup
updated 102 packages in 3.499s
现在我也有一个Dockerfile基于 node：7.10-alpine 映像，如果我尝试在其中安装 npm @ 5 ，该映像将中断。
Yet now I also have a Dockerfile based upon the node:7.10-alpine image which breaks if I try to install npm@5 there.
我的Dockerfile看起来像这样：
My Dockerfile looks like this:
FROM node:7.10-alpine
WORKDIR /usr/hive-updater/
ENV LAST_UPDATED=2016-12-08 NPM_CONFIG_LOGLEVEL=warn TERM=xterm PATH="$PATH:/usr/hive-updater/node_modules/.bin"
RUN npm install npm@5 -g && npm -v
COPY ./ ./
RUN npm run setup
CMD ["node"]
这将在 npm -v 期间失败，并带有：
This will fail during npm -v with:
module.js:472
throw err;
^

如何获取最新的npm我的docker容器？
How to get the latest npm on my docker container?
推荐答案
我发现。
是Facebook的npm替代品您可以使用它全局安装npm @ 5：
Yarn is Facebook's npm replacement and you can use it to globally install npm@5:
RUN npm -v
RUN yarn global add npm@5
RUN npm -v
COPY ./ ./
RUN npm run setup
（版本调用是多余的，仅强调升级有效。）
(The version calls are superfluous and only to highlight that the upgrade works.)
现在它可以工作了：

因此，如果npm版本低于5，并且升级方法不适合您，请安装yarn进行升级npm ¯\_（ツ）_ /¯
So if you have npm below version 5 and its upgrade method breaks for you, install yarn to upgrade npm ¯\_(ツ)_/¯
侧注：
最好只使用yarn而不是npm @ 5。仍然具有强大的性能优势。
It might be better to just use yarn instead of npm@5. It still has a strong performance advantage.
比较这些运行，都将其缓存：
Compare these runs, both cached:
yarn install v0.24.5
[1/4] Resolving packages...
success Already up-to-date.
Done in 0.31s.
和npm @ 5：
npm install
updated 102 packages in 3.069s
I不知道纱线已经随高山图像一起运送了。
I didn't know that yarn was already shipped with the alpine image.
