如何在Ubuntu Web服务器上为Dart安装pub（命令行用法） [英] How to install pub (command line usage) for Dart on Ubuntu web-server

问题描述

我已按照此处（在Linux标签下），将Dart安装到Ubuntu网络服务器上。

I've followed the instructions here (under the Linux tab) on installing Dart onto a Ubuntu web-server.

Dart本身可以正常工作，但我不能使用Pub命令（仅Dart命令）。如何为服务器安装Pub？

Dart itself works fine, but I can't use Pub commands (only Dart commands). How can I install Pub for the server?

推荐答案

以下是Dart使用Aptitude的64位版本Ubuntu的安装说明（apt）程序包管理器（在网站上找到）：

Here are Dart’s installation instructions for 64bit version of Ubuntu using the Aptitude (apt) package manager (as found on the website):

# Enable HTTPS for apt. 
$ sudo apt-get update 
$ sudo apt-get install apt-transport-https 

# Get the Google Linux package signing key. 
$ sudo sh -c 'curl https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -' 

# Set up the location of the stable repository.
$ sudo sh -c 'curl https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list' 
$ sudo apt-get update 
$ sudo apt-get install dart

不过，在此之后，即使Dart语言也无法在终端中使用Pub命令（您可能有所不同，请尝试输入'pub –-help ' 查看）。在这种情况下，可以通过将Dart添加到 .profile路径中来手动启用发布。

After this though, it’s likely that the Pub commands will not work in the terminal even if the Dart language does (yours might be different, try entering ‘pub –-help’ to see). If this is the case, Pub can be enabled manually by adding Dart to the ‘.profile’ PATH.

新安装的Dart文件很可能位于 / usr / lib / dart目录中（如果不确定，请进行检查）。知道后，通过输入以下内容来编辑 .profile文件：

It’s likely that the newly installed Dart files will be located in the ‘/usr/lib/dart’ directory (do check this if unsure). Once known, edit the ‘.profile’ file by entering:

nano ~/.profile

这将使用nano编辑bash配置文件（如果已安装，则使用其他命令行文件编辑器）。现在，在文件底部，添加：

This will edit the bash profile using nano (if installed, else use another command line file editor). Now at the bottom of the file, add:

export PATH="$PATH:/usr/lib/dart/bin"

完成后，您可以输入 cat〜/ .profile来检查它是否已保存。现在，通过输入以下内容来强制重新加载bash配置文件：

When finished, you can check it has saved afterwards by entering ‘cat ~/.profile’. Now force the bash profile to reload by entering:

. ~/.profile

再次输入'pub –help'进行检查，并希望显示Pub帮助信息。谢谢GünterZöchbauer的提示;）

Enter ‘pub –help’ again to check and hopefully the Pub help information is shown. Thank you Günter Zöchbauer for the hint ;)
