如何解决 libgomp.spec 在尝试使用 ruby 2.3.8 安装 rmagick gem 时丢失的问题 | Rails 3.2.22.5 |亚马逊 Linux 2018.03

Question

尝试在 Amazon Linux 版本 2018.03

上安装 rmagick 时出错

yum install ImageMagick

之后

尝试gem install rmagick 会导致以下错误。任何 rmagic gem 版本都会发生这种情况。

Answer 1

libgomp.spec 文件在预期位置不可用。为了解决这个问题，我们必须将 libgomp.spec 从 gcc 6.4.1 符号链接到 /usr/lib64/ 目录

ln -s /usr/lib/gcc/x86_64-amazon-linux/6.4.1/libgomp.spec /usr/lib64/libgomp.spec
ln -s /usr/lib/gcc/x86_64-amazon-linux/6.4.1/libgomp.a /usr/lib64/libgomp.a
ln -s /usr/lib64/libgomp.so.1.0.0 /usr/lib64/libgomp.so
