从 Bitbucket 包创建 conda 配方时出错

Question

我在 Bitbucket 上有一个包，其中包含 Python、R 和 bash 中的代码文件。 我正在使用一台运行 Linux CentOS 7 的笔记本电脑。

我想为它创建一个conda package。我已经开始创建一个 conda 配方，但我可能犯了一些错误。我正在使用 conda 4.3.18。 我尝试使用以下命令构建我的 conda 配方，但它产生了几个我无法解释的错误：

$ conda build behst_conda_recipe/

有谁知道这些错误是什么意思？

编辑：这是 meta.yaml 文件：

package:

  name: behst

source:

  hg_url: https://bitbucket.org/PROJECT_ADDRESS

about:

  home: https://bitbucket.org/PROJECT_ADDRESS
  license: BSD
  license_file: LICENSE

虽然此时的 build.sh 只是一个 echo 命令：

#!/bin/bash
#
#$ -cwd
#$ -S /bin/bash
#
set -o nounset -o pipefail -o errexit
set -o xtrace

echo "Running build.sh"

Answer 1

您的主目录是否已加密？这是github上的relatedissues。 解决方案是使用--croot 指向您家外某处的参数，例如/tmp/_conda_build_。

Answer 2

您的主目录似乎已加密。处理加密文件夹时的字符长度从正常的 255 个字符长度减少。

因此，即使根据 conda 的贡献者，唯一的解决方案是将 --croot 与 /tmp/whateverfolder 等非加密位置一起使用

conda config --prepend pkgs_dirs /tmp/temp_conda_recipe 

然后

conda build behst_conda_recipe/ --croot /tmp/temp_conda_recipe
