如何在最新的节点docker映像上将npm升级到npm @ 5？ [英] How to upgrade npm to npm@5 on the latest node docker image?

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;
    ^

Error: Cannot find module 'semver'
    at Function.Module._resolveFilename (module.js:470:15)

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

我发现节点的高山图像附带了纱线。

纱线是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.
