安装unf_ext时，Bundle安装失败。 “安装unf_ext时无法分配内存错误”

Question

I have this bug that happens on my remote server.

Though this isn't replicable in my local environment.

Installing unf_ext 0.0.7.2 with native extensions

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

/home/ubuntu/.rbenv/versions/2.1.2/bin/ruby extconf.rb

Cannot allocate memory - /home/ubuntu/.rbenv/versions/2.1.2/bin/ruby extconf.rb 2>&1

Gem files will remain installed in /home/ubuntu/switch-web/shared/bundle/ruby/2.1.0/gems/unf_ext-0.0.7.2 for inspection.
Results logged to /home/ubuntu/switch-web/shared/bundle/ruby/2.1.0/extensions/x86_64-linux/2.1.0-static/unf_ext-0.0.7.2/gem_make.out
An error occurred while installing unf_ext (0.0.7.2), and Bundler cannot
continue.
Make sure that `gem install unf_ext -v '0.0.7.2'` succeeds before bundling.

I've checked the ram space for my server and it's still pretty decent (2gb free).

Answer 1

我通过升级服务器来修复此问题，增加了内存。

Answer 2

Pretty old question, but I can suggest an alternative answer. Instead of upgrading the server resources (and possibly costs), if the server does not have a swap partition you could temporarily create and enable a swap file:

Run as root:

# create a 512 Mb file
dd if=/dev/zero of=/swapfile1 bs=1024 count=524288

# assign the correct permissions
chown root:root /swapfile1
chmod 0600 /swapfile1

# initialize the file as a swap file
mkswap /swapfile1

# enable swap
swapon /swapfile1

Once the build is complete, you can disable the swap file and delete it:

swapoff /swapfile1
rm /swapfile1
