如何告诉 R 或 Docker 或 Heroku 在部署 Shiny/golem 应用时不要将警告视为错误？

我想上周我已经找到了答案 - 在我的 Dockerfile 中类似于 ENV WARNINGS_ARE_ERRORS=false 的内容 - 但我似乎无法“重新找到”它，因为我的 Google 游戏今天完全失败了； -)

一些关键资源：

• https://cran.r-project.org/web/packages/golem/vignettes/c_deploy.html
• https://github.com/virtualstaticvoid/heroku-buildpack-r

这就是我的 Dockerfile 在结构上的样子

FROM rocker/r-ver:4.0.4
ENV WARNINGS_ARE_ERRORS=false
RUN apt-get update && apt-get install -y  git-core libcurl4-openssl-dev libgit2-dev libicu-dev libpq-dev libssl-dev libxml2-dev make pandoc pandoc-citeproc && rm -rf /var/lib/apt/lists/*
RUN echo "options(repos = c(CRAN = 'https://cran.rstudio.com/'),download.file.method = 'libcurl')" >> /usr/local/lib/R/etc/Rprofile.site
RUN R -e 'install.packages("remotes")'
RUN R -e 'remotes::install_github("r-lib/remotes",ref = "97bbf81")'
RUN Rscript -e 'remotes::install_version("shiny",upgrade="never",version = "1.5.0")'
RUN Rscript -e 'remotes::install_version("golem",version = "0.2.1")'

[...]

RUN Rscript -e 'remotes::install_github("rappster/confx")'
RUN mkdir /build_zone
ADD . /build_zone
WORKDIR /build_zone
RUN R -e 'remotes::install_local(upgrade="never")'
CMD R -e "options('shiny.port'=$PORT,shiny.host='0.0.0.0');mypkg::run_app()"

这是我遇到的错误的警告：
