如何配置我的`travis.yaml``jobs.include`和`before_install`安装macOS堆栈? [英] How do configure my `travis.yaml` `jobs.include` and `before_install` to install stack for macOS?

问题描述

尽管我已经执行了中所述的步骤说明

before_install:
# Download and unpack the stack executable
- mkdir -p ~/.local/bin
- export PATH=$HOME/.local/bin:$PATH
- travis_retry curl -L https://get.haskellstack.org/stable/linux-x86_64.tar.gz | tar xz --wildcards --strip-components=1 -C ~/.local/bin '*/stack'

我的 travis.yaml 这些失败使用

jobs:
  include:
  ...
  - name: "LTS 9.6 (Haskell for macOS)"
    os: osx
    osx_image: xcode10
    env: ...
    ...

使用

tar: Option --wildcards is not supported
Usage:
  List:    tar -tf <archive-filename>
  Extract: tar -xf <archive-filename>
  Create:  tar -cf <archive-filename> [filenames...]
  Help:    tar --help
curl: (23) Failed writing body (0 != 597)
The command "curl -L https://www.stackage.org/stack/linux-x86_64" failed. Retrying, 2 of 3.

如何修改我的 travis.yaml jobs.include 和 before_install 以便为macOS安装堆栈?

How do I modify my travis.yaml jobs.include and before_install to install stack for macOS?

推荐答案

几件事.

1. 我不会在这里使用 travis_retry ，因为 curl 具有

1. I wouldn't use travis_retry here, since curl has the --retry flag that works better.
2. macOS uses BSD tar, not GNU tar. You can either:

1. 找到可同时在两者上使用的通用标志
2. 安装 gnu-tar 并使用反而.(如果要以 tar 的身份执行此公式，则不仅需要 brew install gnu-tar ，还请务必正确设置.)

1. Find a common flag that works on both
2. Install gnu-tar, and use that instead. (This formula requires more than just brew install gnu-tar, if you want to execute it as tar, so be sure to set it up correctly.)
