无法在ubuntu 16.04成功更新国家预防机制

Question

在这篇文章中，我尝试了一些建议的方法。

如何将Node.js和npm更新到下一个版本？

1) npm更新-g npm

npm update -g npm
/usr/bin/npm -> /usr/lib/node_modules/npm/bin/npm-cli.js
/usr/bin/npx -> /usr/lib/node_modules/npm/bin/npx-cli.js
- asap@2.0.5 node_modules/npm/node_modules/asap
- fstream@1.0.10 node_modules/npm/node_modules/fstream
- balanced-match@0.4.2 node_modules/npm/node_modules/fstream-npm/node_modules/fstream-ignore/node_modules/minimatch/node_modules/brace-expansion/node_modules/balanced-match
- concat-map@0.0.1 node_modules/npm/node_modules/fstream-npm/node_modules/fstream-ignore/node_modules/minimatch/node_modules/brace-expansion/node_modules/concat-map
- brace-expansion@1.1.6 node_modules/npm/node_modules/fstream-npm/node_modules/fstream-ignore/node_modules/minimatch/node_modules/brace-expansion
...
- realize-package-specifier@3.0.3 node_modules/npm/node_modules/realize-package-specifier
/usr/lib
`-- npm@5.5.1 

但是，当我尝试使用npm --version时，它的错误消息失败了：

# npm --version
module.js:471
    throw err;
    ^

Error: Cannot find module 'process-nextick-args'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)

    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

2)卷曲https://www.npmjs.com/install.sh _ sh

# curl https://www.npmjs.com/install.sh | sh

但是npm命令在系统中不可用。文件似乎根本没有安装。

# ls -l /usr/bin/npm
lrwxrwxrwx 1 root root 38 Nov  3 01:26 /usr/bin/npm -> ../lib/node_modules/npm/bin/npm-cli.js
# ls /usr/lib/node_modules/npm/bin/npm-cli.js
ls: cannot access '/usr/lib/node_modules/npm/bin/npm-cli.js': No such file or directory

我的running正在码头集装箱里运行。下面是dockerfile：

FROM ubuntu:16.04

RUN apt-get update --fix-missing && apt-get install -y vim libcairo2-dev libjpeg8-dev libpango1.0-dev libgif-dev build-essential g++


RUN curl -sL https://deb.nodesource.com/setup_6.x | bash -
RUN apt-get install -y nodejs
# RUN apt-get install -y npm

RUN update-alternatives --install /usr/bin/node node /usr/bin/nodejs 10

那么，升级npm的最新方式是什么呢？

Answer 1

您可以为此使用Node (NVM)。尝试使用以下命令。我在使用节点时遇到了很多问题，但是下面的内容总是有效的。

//This will install npm v5.4, this might break if you're using node 4.5 and 4.6
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash

//To uninstall a node version 
nvm uninstall <current version>

nvm install 8.5.0

nvm use 8.5.0

//check with 
node -v

如果您使用它与码头，最简单的方法是直接使用节点码头从码头枢纽

例：

第一次拉动：

docker pull node:6.11.5-wheezy

并将以下内容添加到docker文件中：

FROM node:6.11.5-wheezy
