Question

我已经使用scrapy编写了一个python脚本来抓取一个网站，我正试图通过jenkins建立一个工作来每晚调用脚本（这样很容易看到输出）。

我正在运行jenkins的机器是google compute中的bitnami VM。

我设置了命令以在jenkins中运行shell命令，并且它失败并出现以下错误：

Building on master in workspace /opt/bitnami/apps/jenkins/jenkins_home/jobs/Scrape and Import myco/workspace [workspace] $ /bin/sh -xe /opt/bitnami/apache-tomcat/temp/hudson4165433582945317339.sh

我很困惑，因为当我运行相同的命令时（因为我的用户和用户jenkins在tomcat下运行）我没有收到此错误，脚本运行正常。

我怀疑这可能与在apache中执行的脚本有关，但我在我的智慧结束并且谷歌搜索没有找到任何明显的解决方案。

如何解决这个问题？

Answer 1

符号EC_GFp_nistp521_method，版本OPENSSL_1.0.1未在文件libcrypto.so.1.0.0中定义

看起来你正在运行一个用OpenSSL 1.0.1编译的python和一个来自OpenSSL 1.0.0的libcrypto。这可能是因为你使用不同的python运行（至少针对不同的OpenSSL版本编译），但是包含来自本地python安装的文件，这些文件需要更新的OpenSSL。

在Jenkins中执行作业时出现OPENSSL_1.0.1错误
