# Make sure we don't accidentally restore a cache that contains the Metro
|
|
|
|
|
# filename issue that was fixed in Metro 0.25, originally introduced in
|
|
|
|
|
# D6752278. Once fixed, this was causing sporadic failures in the iOS
|
|
|
|
|
# and tvOS workflows as the issue persisted in the cached node_modules
|
|
|
|
|
#
|
|
|
|
|
# The filename issue can be summarized as follows:
|
|
|
|
|
# A version of Metro was published to npm with HmrClient.js and
|
|
|
|
|
# HmrClient.js.flow files, while the repo contains HMRClient.js and
|
|
|
|
|
# HMRClient.js.flow. This was due to a case issue in the publisher's
|
|
|
|
|
# host machine.
|
|
|
|
|
# The issue this is checking for is manifested by the presence of all
|
|
|
|
|
# of the following files: HmrClient.js, HMRClient.js, HmrClient.js.flow,
|
|
|
|
|
# HMRClient.js.flow.
