arc lint 命令失败并出现错误 #1答案

【问题标题】：arc lint command fails with error #1arc lint 命令失败并出现错误 #1

【问题描述】：

我已通过在 .arclint 文件中定义 linter 将 arc lint 配置为使用 pylint：

{
  "linters": {
    "pylint": {
      "type": "pylint",
      "include": "(\\.py$)"
    }
  }
}

在任何*.py 上执行arc lint 命令后，我得到下一个异常：

[2016-07-12 14:18:10] EXCEPTION: (PhutilAggregateException) Some linters failed:

我的arc --version 输出：

libphutil 32c56dc20b39cffd0cfef931f6f4ab9c99f12677（2016 年 7 月 7 日）

我的pylint --version 输出：

我在 PHP 5.5.34 遇到异常，升级到 PHP 5.6.23 后问题仍然存在。我也尝试安装其他版本的奥术师但没有成功 - arcanist 57f6fb59d73994d90cd94143787424ce0fdbf73b (25 Jan 2016)，libphutil f43291e99d36045bc459e5133454c0d8fd8768ea (21 Jan 2016)。

操作系统：El Capitan 10.11.5

【问题讨论】：

您是否尝试在控制台中手动运行 pylint 命令？我已经尝试了 arc lint --everything 与您提供的 .arclint 文件，它工作得很好。我有 Pylint 1.6.1 版
@KostyaShkryob 是的，我试过了，效果很好。另外，我试过 pylint 1.6.1 没有成功。

【解决方案1】：

就我而言，问题与ValueError: unknown locale: UTF-8 有关。

如果您在 MacOS 上遇到同样的错误，这里是快速修复（在 bash 中导出）：

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

如何解决：

请使用“test.php”脚本重现问题（提供文件路径而不是“path-to-file/file”）：

<?php
$descriptorspec = array(
    0 => array("pipe", "r"),
    1 => array("pipe", "w"),
    2 => array("file", "error_output.txt", "a")
);
$process = proc_open('"pylint" "--reports=no" "--msg-template={line}|{column}|{msg_id}|{symbol}|{msg}"   "path-to-file/file"', $descriptorspec, $pipes);
if (is_resource($process)) {
    fclose($pipes[0]);
    echo stream_get_contents($pipes[1]);
    fclose($pipes[1]);
    $return_value = proc_close($process);
    echo "command returned $return_value\n";
}
?>

您可以检查“error_output.txt”文件中是否存在错误。

祝你好运！ :)
