的NodeJS在Ubuntu

Question

安裝的問題，我在Ubuntu安裝使用以下命令的NodeJS

捲曲-SL https://deb.nodesource.com/setup_8.x |須藤-E慶典 - sudo易於得到安裝-y的NodeJS

然後給出了這樣的消息，

Reading package lists... Done

nodejs is already the newest version. 
0 upgraded, 0 newly installed, 0 to remove and 253 not upgraded. 
W: Duplicate sources.list entry https://dl.bintray.com/sbt/debian/ Packages (/var/lib/apt/lists/dl.bintray.com_sbt_debian_Packages) 
W: You may want to run apt-get update to correct these problems 

當我執行 「sudo apt-get的更新」，我得到另一個錯誤，

W: Failed to fetch http://ppa.launchpad.net/chris-lea/node.js/ubuntu/dists/wily/main/binary-amd64/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead. 

您能否讓我知道如何解決這個問題？發生

Answer 1

的錯誤，因爲四個源鏈接，您（或安裝程序）添加到您的/etc/apt/sources.list都沒有找到，返回錯誤404

如果說項不在/etc/apt/sources.list，你可以找到他們的一些文件/etc/apt/sources.list.d/*.list 。

刪除包含這些URL的線在你/etc/apt/sources.list（或某些文件/etc/apt/sources.list.d/*.list），並安裝Node.js的官方途徑：

https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - 
sudo apt-get install -y nodejs 

或者，如果你想第6版：

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - 
sudo apt-get install -y nodejs 

備註

也許你會遇到這個問題，因爲你的Ubuntu版本不受支持。 我不認爲他們支持15.10，但只有LTS版本（14.04 & 16.04）。

如果可以，請升級到16.04並重試。
