从 PHP 文件调用 "npm run generate" 导致 "npm ERR! code ELIFECYCLE"

Question

我正在从 PHP 调用 npm run generate 以从 NuxtJS 生成静态站点。运行下面的代码导致 Return 代码：254 - npm ERR！代码 ELIFECYCLE.

<?php
exec("export PATH=/www/htdocs/w01234567/nodejs/bin && npm run generate 2>&1", $out, $result);
echo "ReturnCode: " .$result ."<br>";
echo "Output: " ."<br>";
echo "<pre>"; print_r($out);
?>

generate.php 文件与所有 NuxtJS 文件位于同一文件夹中。 (https://example.com/12345/generate.php)

如果我通过 SSH（通过 PuTTY）调用 npm run generate，它仍然有效。

到目前为止我尝试过的：

Update/reinstall全部node_modules
Update/reinstall nodejs/npm

如何解决这个错误？

-export PATH=/www/htdocs/w01234567/nodejs/bin
+export PATH=/www/htdocs/w01234567/nodejs/bin:$PATH

您正在完全覆盖 PATH 而不是在其前面添加，因此 npm 脚本无法运行，因为 npm 会退出。

编辑：

在聊天中，我们发现PHP脚本中根本不存在PATH，于是手动重新构建：export PATH=/www/htdocs/w123456/nodejs/bin:/usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin && npm run generate 2>&1"。为什么 PATH 在我们不知道的 PHP 脚本中不可访问，但是从通用路径手动构建它是可行的。

从 PHP 文件调用 "npm run generate" 导致 "npm ERR! code ELIFECYCLE"

Calling "npm run generate" from PHP file results in "npm ERR! code ELIFECYCLE"
