无法找到语言包 language-pack-en。

Question

我的NodeJS服务器在运行 Docker 镜像中...

Dockerfile

FROM node:4.8-slim
RUN apt-get update -y && \
    apt-get install -yqq locales git

...没有安装英语本地化:

RUN locale -a

给我

C
C.UTF-8
POSIX

在我的Dockerfile中，我尝试添加缺失的语言

RUN apt-get install -y language-pack-en

但是这让我感到

Reading package lists...
Building dependency tree...
Reading state information...
E: Unable to locate package language-pack-en

那么我该如何添加缺失的语言包？

更新

使用

sudo locale-gen en_US
sudo locale-gen en_US.UTF-8
sudo update-locale 

给我返回这个错误：

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = "en_US:en",
    LC_ALL = "en_US.UTF-8",
    LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to 

默认语言环境：没有这样的文件或目录

Answer 1

如果它是Debian镜像，你可以在Dockerfile中添加以下内容：

RUN apt-get install -y locales locales-all
ENV LC_ALL en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US.UTF-8

Answer 2

尝试:

export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_TYPE=en_US.UTF-8
sudo locale-gen
sudo dpkg-reconfigure locales

Answer 3

通常情况下，您可以使用以下方式安装其他语言环境：

sudo locale-gen en_US
sudo locale-gen en_US.UTF-8
sudo update-locale 

然后您可以更改 /etc/default/locale 中的值。
