如何配置`travis.yaml` `jobs.include`和`before_install`以安装适用于macOS的堆栈？

Question

尽管我已经实现了步骤described in the instructions

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'

在my travis.yaml这些fail中，当我尝试在macOS上使用

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travis.yaml jobs.include和before_install以安装适用于macOS的堆栈？

Answer 1

有几件事。

1. 我不会在这里使用travis_retry，因为curl有更好的--retry flag，
2. macOS使用的是BSD tar，而不是tar。您可以选择：
   1. 找到一个在两个
   2. Install gnu-tar上都有效的通用标志，然后使用它。(如果您希望以correctly.)

的身份执行此公式，则它需要的不仅仅是brew install gnu-tar，因此请确保将其设置为tar
